A smart lock for a metal door needs to match the door’s thickness, cutouts, frame, and locking hardware—not just offer fingerprint or app access. My best overall pick is the Philips 4200 Series Wi-Fi Smart Deadbolt with Keypad, Fingerprint Unlock, and Handle Set, which combines several entry methods with a coordinated handle set. The Wyze Lock Bolt v2 is a more focused fingerprint-and-keypad option, while the Eseesmart Sliding Glass Door Lock suits a different door style altogether. The main tradeoffs are fit and installation compatibility versus convenience features, connectivity, and the type of lock your door can accept. Read on for the full breakdown, buying advice, and answers to common fit questions.

Key Takeaways
- The Philips 4200 Series Wi-Fi deadbolt with handle set stands out as the broadest all-around choice here because it pairs fingerprint and keypad entry with Wi-Fi features and a matching handle; check the door prep before choosing it.
- Several Philips listings offer overlapping keypad, fingerprint, Wi-Fi, and handle features, so compare the exact included hardware and lock configuration rather than relying on the series name alone.
- The Wyze Lock Bolt v2 and eufy Security Smart Lock C220 put fingerprint access at the center of the experience, while the TEEHO TE001 is a simpler keypad-only alternative for buyers who do not need biometrics.
- Gate locks and the Eseesmart sliding-glass lock address different hardware and door types from standard deadbolts; they should not be treated as direct substitutes for a deadbolt on a metal entry door.
- Face recognition, camera, and doorbell features make the TianfuSpanda the most feature-heavy concept in this lineup, but added functions do not replace checking physical fit, power needs, and installation requirements.

More Details on Our Top Picks
Eseesmart Smart Sliding Glass Door Lock with Fingerprint, Keypad, RFID, Bluetooth App, and Handle
For a metal-framed sliding door, the Eseesmart YL-D208F is the most purpose-matched pick here: its sliding-door format and 22–120 mm thickness range give it a broader fit than the Philips 4200 Series deadbolts, which are designed for conventional hinged doors. Five entry methods—fingerprint, passcode, Bluetooth app, RFID card, and mechanical key—make it practical for households or shared spaces where users prefer different credentials. Its 300-user capacity also exceeds the Wyze Lock Bolt v2’s listed capacity of 50 fingerprints and 50 codes. The tradeoff is that Bluetooth is not the same as built-in Wi-Fi remote access, so app control is more limited when away from the door. It also runs on batteries, with life stated at up to eight months, and fit still depends on the sliding door’s lock preparation.
Pros:- Designed for sliding doors and supports door thicknesses from 22 to 120 mm
- Offers fingerprint, passcode, Bluetooth app, RFID card, and mechanical-key access
- Supports up to 300 users and has a reversible handle
- Includes low-battery alerts, emergency power-bank support, and an IP65 rating
Cons:- Bluetooth connectivity does not provide the same away-from-home access as the built-in Wi-Fi Philips and Wyze options
- Battery life is stated at up to eight months, so batteries need periodic replacement
- Sliding-door hardware and lock preparation may limit fit despite the wide thickness range
Best for: Owners of metal-framed sliding doors who need several entry methods and access for a large household, staff, or other shared users.
Not ideal for: Buyers who need remote unlocking over Wi-Fi from outside Bluetooth range, or whose door is a standard hinged deadbolt rather than a compatible sliding-door setup.
- Unlock methods:Fingerprint, passcode, Bluetooth app, RFID card, mechanical key
- User capacity:Up to 300 users
- Compatible door thickness:22–120 mm
- Connectivity:Bluetooth
- Handle:Reversible for left- or right-opening doors
- Battery life:Up to 8 months
- Dimensions:1.37 × 2.16 × 12.6 inches
Our verdict“Choose the Eseesmart if your metal door is a compatible sliding door and broad access options matter more than built-in Wi-Fi remote control.”
Philips 4200 Series Wi-Fi Smart Deadbolt with Keypad, Fingerprint Unlock, and Handle Set
The Philips 4200 Series suits buyers replacing a conventional deadbolt and handle on a metal door, provided the door is 38–50 mm thick and has compatible standard hardware. Unlike the Eseesmart sliding-door lock, this Philips set pairs a deadbolt with two levers and connects directly to 2.4 GHz Wi-Fi, so app control does not depend on being near the lock. Fingerprint, PIN, app, and Alexa or Google Assistant access give it a useful mix for everyday entry and remote management. The Philips DDL242X-1HW-L offers more detailed PIN types and an explicitly listed auto-lock range, while this model’s listing highlights app access history. The main compromises are eight AA batteries that are not included and limited Wi-Fi band support; it is not a fit for every metal door just because the material is metal.
Pros:- Built-in 2.4 GHz Wi-Fi enables app control without a separate hub
- Combines fingerprint, PIN, app, and Alexa or Google Assistant access
- Includes two matching door levers, latch assembly, and mounting hardware
- App features include remote control and access history
Cons:- Fits only doors 38–50 mm thick with compatible deadbolt preparation
- Requires eight AA alkaline batteries, which are not included
- Connects only to 2.4 GHz Wi-Fi
Best for: Homeowners with a standard-prepped, 38–50 mm metal entry door who want a matched lever set, fingerprint entry, and remote app access over Wi-Fi.
Not ideal for: Owners of sliding doors, unusually thick or thin metal doors, or homes that rely on 5 GHz-only Wi-Fi or do not want to supply eight AA batteries.
- Model:DDL242X-1HW
- Connectivity:2.4 GHz Wi-Fi; no hub required
- Unlock methods:Fingerprint, PIN code, app, voice assistant
- Door thickness:1⅜–1¾ inches (38–50 mm)
- Auto-lock:Adjustable from 0 to 180 seconds
- Power:Eight AA alkaline batteries; not included
- Voice compatibility:Alexa and Google Assistant
- Finish:Satin nickel
Our verdict“Pick this Philips set for a compatible hinged metal entry door when Wi-Fi app access and a coordinated handle set matter more than flexible door fit.”
EIYSIE WiFi Smart Gate Lock with Dual-Sided Fingerprint Access
The EIYSIE is the clearest choice here for a metal gate or outdoor door where people need to enter from either side: it places fingerprint readers and keypads on both faces, unlike the single-sided access setup described for the Philips 4200 Series. Its IP65 rating, support for 20–80 mm doors, and five access methods make it more gate-oriented than the indoor-focused deadbolt sets. Tuya Wi-Fi features add remote unlocking, temporary passwords, user management, and access logs without a hub. That outdoor flexibility comes with more demanding installation: drilling is required, so the door’s construction and lock layout must be checked before purchase. It also lacks Alexa and Google support. Compared with the Eseesmart, this is the better fit for a gate with two-sided access needs, but not for a sliding-door replacement.
Pros:- Fingerprint readers and keypads provide access from both sides
- Supports wood or metal doors from 20 to 80 mm thick
- IP65 rating and Wi-Fi Tuya app access suit outdoor gate use
- Offers fingerprint, PIN, IC card, app, and physical-key entry
Cons:- Installation requires drilling and may be difficult on an existing metal gate
- Does not support Alexa or Google Assistant
- App language can only be changed before a password is set
Best for: Property owners fitting a compatible wood or metal gate who need fingerprint and keypad access from both sides, plus remote user management.
Not ideal for: Renters or DIY buyers unwilling to drill, anyone seeking a sliding-door lock, or smart-home users who require Alexa or Google voice control.
- Unlock methods:Fingerprint, PIN, IC card, mobile app, physical key
- Fingerprint capacity:Up to 100 fingerprints
- User profiles:Up to 200
- Connectivity:Wi-Fi through the Tuya app; no hub required
- Door thickness:20–80 mm
- Compatible materials:Wood or metal
- Installation:Requires drilling
- Voice assistant compatibility:Not compatible with Alexa or Google
Our verdict“Choose the EIYSIE for a drill-compatible outdoor metal gate when two-sided biometric access matters more than voice-assistant support or easy installation.”
Philips 4200 Series Wi-Fi Keypad Deadbolt with Handle and Fingerprint Access
For a standard metal entry door shared with visitors, tenants, or office users, this Philips 4200 Series stands out for its permanent, one-time, periodic, and recurring PIN codes. Those code choices make access scheduling clearer than the less-detailed PIN options listed for the Philips DDL242X-1HW, while its app also handles fingerprints, lock status, and history. Built-in 2.4 GHz Wi-Fi, Alexa and Google Assistant support, and a matching handle set cover the connected-entry basics without a hub. Fit is narrower than the EIYSIE gate lock: this model is for 38–50 mm hinged doors, not a drilled gate or sliding panel. Buyers must also enable auto-lock themselves, supply alkaline batteries, and keep the lock within a recommended 33 feet of the router with limited obstacles.
Pros:- Supports permanent, one-time, periodic, and recurring PIN codes
- App provides access-code management, fingerprint management, lock status, and history
- Connects to 2.4 GHz Wi-Fi without a hub and works with Alexa and Google Assistant
- Includes two door levers and adjustable auto-lock settings
Cons:- Requires standard 1.5V alkaline batteries, which are not included
- Auto-lock is off by default and must be enabled manually
- Recommended Wi-Fi range is within 33 feet of the router with limited obstacles
Best for: Hosts, landlords, and small offices with a standard-prepped metal door who need scheduled PIN access and remote status checks.
Not ideal for: Owners of gates or sliding doors, doors outside the 38–50 mm range, or installations far from the Wi-Fi router.
- Model:DDL242X-1HW-L
- Connectivity:2.4 GHz Wi-Fi; no hub required
- Unlock methods:Keypad PIN, fingerprint, app, voice assistant
- PIN code types:Permanent, one-time, periodic, recurring
- Fingerprint unlock time:0.3 seconds
- Auto-lock delay:0–180 seconds; off by default
- Door thickness:1⅜–1¾ inches (38–50 mm)
- Door orientation:Right-opening by default; can be reset for left-opening
Our verdict“Choose this Philips model over the other 4200 Series option when varied guest-code schedules are your priority and your metal door matches its standard deadbolt fit.”
Wyze Lock Bolt v2 Fingerprint Smart Deadbolt with Wi-Fi
The Wyze Lock Bolt v2 keeps the entry choices familiar: fingerprint, keypad code, app, or backup key, with built-in Wi-Fi for remote lock control. That makes it a simpler alternative to the Eseesmart, which adds RFID and a reversible handle for sliding-door use, and to the EIYSIE, which is built for two-sided gate access. Wyze is a deadbolt rather than a gate or sliding-door lock, so the metal door needs compatible deadbolt preparation; the supplied data does not state a door-thickness range. USB-C emergency power, auto-lock, and tamper alarms add useful backup and security functions. Its IP53 rating is lower than the EIYSIE’s IP65, making it a less convincing fit for exposed outdoor locations. Eight AA batteries are included, but remote features still depend on Wi-Fi.
Pros:- Offers fingerprint, keypad, app, and backup-key access
- Built-in Wi-Fi supports remote lock control
- Includes auto-lock, tamper alarms, and USB-C emergency power
- Includes eight AA batteries and supports up to eight months of battery life
Cons:- IP53 weather resistance is lower than the EIYSIE gate lock’s IP65 rating
- Capacity is limited to 50 keypad codes and 50 fingerprints
- Remote access depends on a working Wi-Fi connection, and door-thickness compatibility is not specified in the supplied data
Best for: Buyers with a compatible standard metal deadbolt door who want fingerprint and keypad entry, built-in Wi-Fi, and emergency USB-C power.
Not ideal for: Owners of sliding doors or exposed gates needing a higher stated weather rating, or buyers who need more than 50 stored codes or fingerprints.
- Model:WLCKB2
- Lock type:Biometric deadbolt with keypad
- Unlock methods:Fingerprint, keypad code, app, backup key
- Connectivity:Wi-Fi
- Keypad capacity:Up to 50 codes
- Fingerprint capacity:Up to 50 fingerprints
- Weather resistance:IP53
- Emergency power:USB-C
- Batteries:Eight AA batteries included
Our verdict“Choose the Wyze for a compatible metal deadbolt door when familiar keyless access and USB-C backup matter more than gate-specific fit or stronger weather protection.”
YUVEAI Smart Gate Lock with Fingerprint, PIN, IC Card, App, and Key Access
For a metal gate exposed to the weather, the IP65-rated body and five entry methods give this YUVEAI a clearer fit than the indoor-oriented Philips Wi-Fi Front Lock Set. Fingerprint, IC card, PIN, app, and key access let household members choose what works, while TUYA app control over 2.4 GHz Wi-Fi supports remote management and access codes. Auto-lock and a low-battery alert address common gate-use concerns, and USB-C emergency power offers a fallback if the four AA batteries run down.
The fit is not universal: the gate must be 1.38–2.9 inches thick, and reliable auto-lock requires a frame gap under 6 mm. I would skip it if the frame cannot meet that clearance or the site only has 5 GHz Wi-Fi. Batteries are also not included.
Pros:- Five access methods, including fingerprint, IC card, PIN, app, and mechanical key
- IP65 weather protection for outdoor gate use
- TUYA app supports remote control and access-code management
- USB-C emergency power and automatic locking
Cons:- App setup requires 2.4 GHz Wi-Fi and does not support 5 GHz
- Four AA batteries are not included
- Reliable auto-lock depends on a frame gap under 6 mm
Best for: Homeowners fitting an exposed metal gate who want fingerprint entry, shared access options, and remote code management.
Not ideal for: Buyers whose gate has more than a 6 mm frame gap, falls outside the supported thickness range, or lacks 2.4 GHz Wi-Fi for app setup.
- Unlock methods:Fingerprint, IC card, PIN, mobile app, mechanical key
- App:TUYA
- Wi-Fi:2.4 GHz; does not support 5 GHz
- Door thickness:1.38–2.9 inches (35–74 mm)
- Weather protection:IP65
- Power:4 AA batteries, not included
- Battery life:Up to 6 months
- Emergency power:USB-C power bank
- Auto-lock:Yes
Our verdict“Choose this for a weather-exposed metal gate that meets its thickness and frame-clearance requirements; skip it if your installation cannot.”
Philips Wi‑Fi Front Lock Set – Smart Keypad Deadbolt with Two Handles
This Philips set makes the most sense when replacing a deadbolt and handles together on a metal entry door. The included handle pair gives the installation a coordinated finish, while fingerprint, PIN, app, key, and voice-assistant access cover different household routines. Remote app control and real-time notifications are useful when you want to check access without being at the door. Compared with the YUVEAI gate lock, this is aimed at a conventional front door, not an exposed gate; its listed fit is also narrower at 35–50 mm.
The adjustable 30–180-second auto-lock timer lets you choose how quickly the door secures itself. That convenience does not overcome the thickness limit, though, and the product data does not give a weather-resistance rating for outdoor gate exposure. I would confirm the door dimensions before choosing it for a metal door.
Pros:- Includes a matching handle set with the smart deadbolt
- Fingerprint, PIN, app, key, and voice-assistant access
- Remote app management with real-time notifications
- Adjustable auto-lock timer from 30 to 180 seconds
Cons:- Fits only doors 35–50 mm thick
- No weather-resistance rating is provided in the product details
Best for: Owners of standard-thickness metal entry doors who are replacing both a keypad deadbolt and matching handles.
Not ideal for: Buyers with a door outside the 35–50 mm range or anyone seeking a lock specifically rated for exposed outdoor gate conditions.
- Model:DDL240X-1HW-H2
- Door thickness:35–50 mm
- Unlock methods:App, fingerprint, PIN code, key, Alexa or Google voice assistant
- Connectivity:Wi-Fi
- Auto-lock timer:30–180 seconds, adjustable
- Batteries:4 included
- Included components:Door lock, handle set, 4 batteries
Our verdict“Pick this Philips set when coordinated handles and remote access matter on a compatible metal front door, not an exposed gate.”
Philips Wi-Fi Smart Lock with Handle and Fingerprint Keyless Entry
Among these picks, this Philips is the stronger fit for a busy household that needs lots of distinct credentials: it stores up to 50 fingerprints and 100 passcodes, with permanent, scheduled, and temporary code options. Built-in 2.4 GHz Wi-Fi means remote control and activity logs do not require a separate hub. Compared with the simpler TEEHO TE001 keypad deadbolt, it adds biometrics, app access, and passage and privacy modes, but also asks more of the door and uses twice as many batteries as the TEEHO.
Check the installation dimensions carefully on a metal door: it needs a 2-1/8-inch hole, a specified backset, and at least 4.53 inches of clearance between the deadbolt and handle set. The eight AA batteries are not included, so ongoing battery replacement is part of the ownership tradeoff.
Pros:- Stores up to 50 fingerprints and 100 passcodes
- Built-in 2.4 GHz Wi-Fi enables remote access without a hub
- Supports activity logs, passage mode, and privacy mode
- Auto-lock timer is adjustable from 5 to 180 seconds
Cons:- Requires eight AA alkaline batteries, which are not included
- Specific hole, backset, thickness, and handle-clearance requirements may rule out some doors
- More features and credentials may be unnecessary for buyers who only need keypad entry
Best for: Households, landlords, or hosts who need many fingerprint profiles and flexible codes for regular guests.
Not ideal for: Buyers with limited clearance, incompatible door preparation, or a preference for a basic keypad lock with fewer batteries.
- Model:DDL220X-1HW-MB
- Unlock methods:Fingerprint, app, password, voice control, physical key
- Fingerprint capacity:Up to 50
- Passcode capacity:Up to 100
- Wi-Fi:Built-in 2.4 GHz; no hub required
- Door thickness:1-3/8 to 2 inches
- Required door hole:2-1/8 inches (54 mm)
- Required clearance:At least 4.53 inches (115 mm) between deadbolt and handle set
- Batteries:8 AA LR6 alkaline batteries, not included
Our verdict“Choose this for a compatible metal door with frequent guest turnover and a need for many credentials; choose the TEEHO for simpler keypad access.”
TEEHO TE001 Keyless Entry Deadbolt with Keypad, Satin Nickel
The TEEHO TE001 is the straightforward choice here for a metal door when the priority is code entry rather than app control or fingerprints. It supports 20 user codes plus a single-use code, so a family can have individual access while a guest gets a temporary credential. One-touch locking and a configurable auto-lock delay add convenience without the added setup of the YUVEAI or Philips smart locks. Its stated battery life of up to 365 days also means fewer planned battery changes than the YUVEAI’s stated six months, though actual results depend on use.
This is not a connected lock: the supplied details do not list app or remote management. It also requires a 2-1/8-inch door hole and is not compatible with 38 mm holes. IP54 weather resistance offers some protection, but the YUVEAI’s IP65 rating is the stronger match for more exposed gate locations.
Pros:- Provides 20 user codes and a temporary single-use code
- One-touch locking and adjustable automatic locking
- Includes two backup keys and a low-battery indicator
- IP54 weather resistance
Cons:- No app, Wi-Fi, or remote-access features are listed
- Requires a 2-1/8-inch (54 mm) door hole and is incompatible with 38 mm holes
- Four AA batteries are not included
Best for: Families with a prepared metal entry door who want shared and temporary keypad codes without app or biometric features.
Not ideal for: Buyers who need remote access, fingerprint entry, stronger listed weather protection, or a door with a 38 mm hole.
- Model:TE001
- Finish:Satin Nickel
- Access codes:20 user codes plus a temporary single-use code
- Auto-lock delay:10–99 seconds; off by default
- Power:4 AA batteries, not included
- Battery life:Up to 365 days
- Weather resistance:IP54
- Door hole size:2-1/8 inches (54 mm)
- Warranty:2 years
Our verdict“Choose the TEEHO for dependable code-based access on a compatible metal door; choose a connected model if you need remote control or fingerprints.”
Veise VE017 Fingerprint Smart Door Lock with App Control, Matte Black
The Veise VE017 earns this spot for buyers who want several ways to enter without making every user rely on a fingerprint. It combines fingerprint, PIN, fob, app, shared code, and mechanical-key access, with one-time, scheduled, recurring, and permanent password modes. The KK Home app also supports permissions, alerts, and activity logs, while encrypted local data storage keeps access information on the lock. Compared with the Philips DDL220X, it offers fob access and a stated IP55 rating, but Philips lists higher capacities for fingerprints and passcodes and includes Wi-Fi without a separate gateway.
For a metal door, its zinc-alloy construction and DIY installation are appealing, and automatic handing detection avoids a left-versus-right setup guess. App features are not all included in the lock itself: remote access and voice-assistant control require the separately sold G1 Gateway. Batteries are also not included, and stated battery life varies with usage.
Pros:- Offers fingerprint, app, PIN, fob, shared-code, and mechanical-key entry
- Supports one-time, duration, permanent, and recurring password modes
- Stores access data locally with AES-128 encryption
- DIY installation with automatic detection of door handing
Cons:- G1 Gateway is sold separately for remote access and voice-assistant features
- Four AA batteries are not included, and battery life varies with usage
- Includes a one-year limited warranty, with an extension requiring registration
Best for: Households or small property managers who want fingerprint, fob, PIN, and app-based access permissions on a metal door.
Not ideal for: Buyers who need remote or voice control without extra hardware, want a longer stated warranty, or prefer batteries included.
- Model:VE017
- Construction:All-metal zinc alloy
- Unlock methods:Fingerprint, app, authorized access, fob card, PIN, shared code, mechanical key; voice assistant with G1 Gateway
- Fingerprint recognition:Under 0.2 seconds; stated 99.99% accuracy
- Auto-lock timer:0–180 seconds
- Data security:AES-128 encrypted; stored on the lock
- Battery:4 AA/LR6 alkaline batteries, not included
- Water resistance:IP55
- Warranty:1-year limited; one-year extension with registration
Our verdict“Pick the VE017 for varied access credentials and local encrypted storage, but budget for the gateway if remote control is part of your plan.”
eufy Security Smart Lock C220 – Fingerprint Keyless Entry Door Lock
For a metal door that already uses a compatible standard deadbolt, the eufy Security Smart Lock C220 offers the most balanced mix of everyday access and remote control in this group. Fingerprint, keypad, key, app, Apple Watch, and voice options give household members alternatives, while built-in Wi-Fi avoids the separate gateway required by the Evanshow Smart Fingerprint Door Lock with Knob. Its eight-AA power supply is easy to replace, though keeping eight batteries on hand is less convenient than a rechargeable pack. The C220’s Grade 3 rating and IP53 resistance also make it a more plausible exterior-door candidate than the non-waterproof TianfuSpanda, but fit matters more than the metal label: it is designed for standard deadbolts and bores under 54 mm. Skip it if your door needs a nonstandard lock body or you want the simplest setup.
Pros:- Six access methods give residents flexibility, including fingerprint, physical key, and voice control.
- Built-in Wi-Fi enables remote access without a separate bridge.
- Eight replaceable AA batteries are rated for up to eight months of use.
- IP53 resistance and BHMA Grade 3 certification offer useful durability details for an exterior-door candidate.
Cons:- Compatibility is limited to standard deadbolts and bores under 54 mm, so a metal door’s existing hardware must be checked.
- It uses eight AA batteries, which may be more upkeep than a rechargeable lock.
- The initial setup may challenge buyers who want a straightforward installation and configuration.
Best for: Households with a compatible standard deadbolt on a metal door that want fingerprint access and remote control without buying a gateway.
Not ideal for: Owners of metal doors with mortise or other nonstandard lock bodies, or buyers who want a very simple setup and fewer batteries to manage.
- Lock type:Deadbolt
- Unlock methods:Fingerprint, app, keypad, physical key, Apple Watch, Alexa or Google Assistant voice control
- Connectivity:Built-in Wi-Fi; no bridge required
- Battery:Eight AA batteries; up to 8 months
- Certification:BHMA Grade 3
- Water resistance:IP53
- Compatibility:Standard deadbolts; bores under 54 mm
- Operating temperature:-22°F to 158°F (-30°C to 70°C)
Our verdict“Choose the C220 if your metal door has a compatible standard deadbolt and you want built-in remote access plus several keyless entry options.”
Evanshow Smart Fingerprint Door Lock with Knob and App Control
The Evanshow 190BT is the most installation-focused choice here: its no-drill, no-wiring design is aimed at compatible doors, and the product data specifies 1.18–1.97-inch-thick wooden doors. That caveat matters for this roundup: although the listed material is metal, the stated door compatibility is wooden, so I would not assume it fits a metal door without checking the manufacturer’s fit requirements. Compared with the eufy C220, it adds NFC card access and app-managed codes and entry logs, but Wi-Fi and voice features require a separate gateway that is not included. Auto-lock helps close the gap for users who worry about forgetting to secure the door. This pick makes sense only when the door construction and dimensions match; skip it for an exposed exterior location or when direct remote access is a must.
Pros:- Fingerprint, keypad, NFC card, and mechanical-key entry provide several ways to get inside.
- App controls support access codes and entry logs.
- Auto-lock can secure the door after a preset interval.
- The stated installation method avoids drilling and wiring on compatible doors.
Cons:- Door compatibility is specified for wooden doors, so fit on a metal door is not established by the provided data.
- Wi-Fi and voice control require a separate gateway that is not included.
- An administrator fingerprint must be registered before first use; until then, any fingerprint can unlock it.
Best for: Renters or homeowners with a compatible, 1.18–1.97-inch-thick door who want fingerprint, code, and NFC access without drilling or wiring.
Not ideal for: Buyers who need confirmed compatibility with a metal door, built-in Wi-Fi, or remote voice control without purchasing a separate gateway.
- Model:190BT
- Entry methods:Fingerprint, keypad passcode, NFC card, mechanical key
- Compatible door thickness:1.18–1.97 inches
- Door handing:Reversible for left- or right-swing doors
- Connectivity:App control; separate gateway required for Wi-Fi or voice control
- App features:Access codes, entry logs, temporary and permanent codes
- Auto-lock:Supported
- Emergency power:USB port for an external power bank; does not charge internal batteries
Our verdict“Pick the Evanshow 190BT only if your door matches its stated fit requirements and you value easy installation over built-in remote connectivity.”
TianfuSpanda Smart Door Lock with 3D Face Recognition, Camera, and Doorbell
The TianfuSpanda takes a different route from the deadbolt-focused eufy C220 and Philips DDL242X-1HW: it combines face recognition, a camera, doorbell, and indoor display in one unit. That can suit a sheltered entry where viewing visitors matters as much as granting access, and its 1080p screen lets someone inside see the door area. The rechargeable 4200 mAh battery and low-battery alert avoid the C220’s eight-AA replacement routine, but the device is explicitly not waterproof, which rules it out for exposed exterior installation. Its installation may also be difficult and can require cutting screws, so this is not the easy retrofit choice in the lineup. I’d shortlist it only for a protected location and a buyer prepared to check the door’s hardware fit and handle a more involved install.
Pros:- Combines a camera, doorbell, and lock, reducing the need for separate visitor-viewing devices.
- Face, fingerprint, card, password, app, and physical-key access offer varied entry options.
- The 1080p indoor display allows occupants to view activity outside the door.
- Rechargeable 4200 mAh battery includes a low-battery alert.
Cons:- It is not waterproof and is unsuitable for exposed outdoor installation.
- Installation may be difficult and may require cutting screws.
- The provided product data does not specify door-thickness or metal-door compatibility.
Best for: Residents with a covered, protected entry who want visitor video, a doorbell, and multiple biometric access methods in one device.
Not ideal for: Buyers installing on an exposed metal exterior door, or anyone seeking a straightforward standard-deadbolt replacement.
- Unlock methods:Face, fingerprint, IC card, password, temporary password, app, WeChat mini program, physical key
- Camera:HD camera with infrared night vision
- Indoor display:1080p color screen
- Battery:Rechargeable 4200 mAh lithium battery
- Connectivity:Wi-Fi; Tuya app control
- Water resistance:Not waterproof
- Included components:Combination lock and installation screw kit
Our verdict“Choose the TianfuSpanda for a sheltered entrance where video and visitor viewing outweigh weather resistance and easy installation.”
Philips Wi-Fi Smart Deadbolt Lock with Fingerprint and Keyless Entry
The Philips DDL242X-1HW stands out for managing many different visitors or household members: it supports up to 100 custom passcodes, plus unlimited one-time or scheduled codes. That is a more practical fit for recurring guests and service access than the Evanshow biometric-only lock, while its built-in 2.4 GHz Wi-Fi provides remote access without a gateway. Fingerprint, app, passcode, physical key, and voice control cover daily entry, and adjustable auto-lock and Away Mode add useful security controls. For a metal door, the deciding factor is the stated 1-3/8 to 2-inch door-thickness range and whether the existing deadbolt layout matches; the product data does not claim universal metal-door fit. Batteries are not included, and there is no door sensor, so it cannot report whether the door itself is open or closed.
Pros:- Stores up to 100 custom passcodes and supports unlimited one-time or scheduled codes.
- Built-in 2.4 GHz Wi-Fi enables remote access without a separate hub.
- Fingerprint, passcode, app, key, and voice control provide multiple entry routes.
- Adjustable auto-lock, Away Mode, alerts, and access history support remote household management.
Cons:- Supports 2.4 GHz Wi-Fi only.
- AA alkaline batteries are required but not included.
- No door sensor is included, so the lock cannot report the door’s open or closed state.
Best for: Households, landlords, or small offices with a compatible deadbolt that need scheduled, temporary, and individual access codes.
Not ideal for: Buyers whose metal door falls outside the stated thickness range, uses a nonstandard lock body, or needs a door-open sensor.
- Model:DDL242X-1HW
- Unlock methods:App, passcode, fingerprint, physical key, Alexa or Google Assistant voice control
- Wi-Fi:Built-in 2.4 GHz; no hub required
- Passcodes:Up to 100 custom codes; unlimited one-time or scheduled codes
- Auto-lock delay:10–180 seconds
- Compatible door thickness:1-3/8 to 2 inches (38–50 mm)
- Battery:AA alkaline (LR6); not included
- Door sensor:Not included
Our verdict“Choose the Philips DDL242X-1HW if your metal door fits its deadbolt dimensions and you need flexible access-code management with built-in Wi-Fi.”
Evanshow Biometric Fingerprint Door Lock with Keypad, Black
This Evanshow model is the stripped-back alternative to the app-connected Evanshow 190BT: it focuses on fingerprint, password, IC card, and mechanical-key access, with room for 100 fingerprints and 50 passwords. That capacity suits a busy household where several people need their own credentials, but the provided specs do not list app control or Wi-Fi, so it cannot match the remote management offered by the Philips DDL242X-1HW or the eufy C220. It is specified for 1.18–1.97-inch-thick wooden doors, making compatibility with a metal door uncertain despite the listed material being metal. The no-drill installation and reversible handing may simplify fitting on a compatible door. Before use, an administrator fingerprint must be registered; USB emergency power can help if power runs low, but it does not recharge the internal batteries.
Pros:- Stores up to 100 fingerprints and 50 passwords for multiple users.
- Offers fingerprint, password, IC card, and mechanical-key entry.
- Reversible design accommodates left- or right-swing doors.
- Stated installation method requires no drilling or wiring on compatible doors.
Cons:- The stated door-thickness compatibility is for wooden doors, so fit on a metal door is not established.
- No app or Wi-Fi control is listed, limiting remote access and management.
- USB emergency power does not recharge the internal batteries, and administrator setup is required before use.
Best for: Families or shared households with a compatible door who want multiple stored fingerprints and codes without relying on app-based access.
Not ideal for: Metal-door owners who need verified hardware compatibility, remote access, or app-managed entry logs and codes.
- Access methods:Fingerprint, password, two mechanical keys, IC card
- Fingerprint capacity:Up to 100
- Password capacity:Up to 50
- Fingerprint recognition:About 0.5 seconds
- Compatible door thickness:1.18–1.97 inches
- Door orientation:Reversible for left- or right-swing doors
- Installation:No drilling or wiring
- Emergency power:USB port for an external power bank; does not charge internal batteries
Our verdict“Choose this Evanshow if your door matches its stated fit and you want local fingerprint and code access without smart-home connectivity.”

How We Picked
I ranked these options by how clearly their listed lock style and access methods suit a metal-door installation, then weighed usability, hardware scope, connectivity, and the chance that a buyer may need door modifications. A fingerprint reader or app connection can add convenience, but neither helps if the lock’s bolt, mounting pattern, or included handles do not match the door. I gave more weight to products with clearly described deadbolt or door-specific hardware than to a long feature list that leaves the intended installation less clear.
The order also reflects different buyer needs rather than treating every model as interchangeable. The Philips 4200 Series set leads for its combination of access methods and coordinated hardware; the Wyze and eufy options are more focused biometric picks, while the TEEHO keypad lock prioritizes simplicity. Gate and sliding-glass products appear lower for a standard metal entry door because their stated use cases are narrower. Product names and feature descriptions alone cannot confirm compatibility: buyers should verify dimensions, door preparation, and handing with the seller or manufacturer before ordering.
Factors to Consider When Choosing Smart Lock For Metal Door
For a metal door, I would start with the lock body and door preparation, then compare convenience features. Metal doors may have different thicknesses, reinforcement, existing cutouts, and frame clearances, so a lock that works on one door can be unsuitable for another. These checks help separate a genuinely compatible choice from a feature-rich model that may require extra work.
Match the Lock Type to the Door
First identify whether your door uses a standard deadbolt, a mortise lock, a narrow-stile mechanism, a sliding panel, or a gate latch. These designs are not interchangeable, even when product listings use similar smart-lock language. A deadbolt model is only a plausible match when the door already has compatible bolt and mounting locations. Measure the lock area and note the door’s edge profile before shopping. A common mistake is assuming that a product described as a door lock will replace any existing lock body. If the door uses a proprietary or multipoint system, ask the manufacturer or a locksmith about supported hardware before buying.
Check Door Thickness, Backset, and Cutouts
Measure door thickness, backset, hole diameter, and the distance between existing mounting holes, then compare each measurement with the lock’s installation specifications. Metal doors can be costly or awkward to drill, and a small mismatch may prevent the inside and outside assemblies from joining correctly. Existing holes do not guarantee a match: older doors may have nonstandard spacing or a different latch shape. Avoid enlarging or drilling openings until you know the door’s reinforcement and construction. If the product page does not list the measurements you need, request them before committing. A model with fewer features but matching hardware can be a better choice than a more elaborate lock that demands door alterations.
Decide Which Entry Methods You Will Actually Use
Fingerprint, keypad, app, RFID card, and physical-key access solve different daily problems. A keypad can serve visitors without requiring them to install an app, while fingerprints can make routine entry quicker for household members. RFID cards and gate access may suit shared or controlled entrances, but they add credential management that some households will not need. Keep a physical backup method in mind, especially if batteries run down or a phone is unavailable. More access methods can mean more setup and more credentials to manage, not automatically a better fit. Choose the smallest set of methods that covers your household’s real use cases.
Treat Wi-Fi and App Features as a Separate Choice
Wi-Fi can support remote access or status checks, while Bluetooth-focused functions may work only when a phone is nearby. Confirm which capabilities work without a hub, what requires an internet connection, and whether the lock’s app supports the features you expect. A built-in fingerprint reader or keypad may cover everyday entry even if the network is unavailable, but remote controls can depend on connectivity and power. Metal structures and the lock’s position can affect wireless reception, so check signal strength at the door rather than assuming indoor coverage will carry through. Buyers who do not need remote management may prefer a simpler model with fewer connected functions. Review app permissions and account requirements before adding a lock to a shared household.
Plan for Installation and the Door Frame
Fit is not only about the lock’s faceplate: the bolt must extend cleanly into a compatible strike plate, and the door must close without pressure against the frame. A misaligned metal door can make a motorized deadbolt bind, drain batteries faster, or fail to lock reliably. Check whether the package includes the handles, latch, strike plate, and mounting hardware needed for your setup. Some listed products are complete handle sets; others describe a deadbolt or lock body, so package contents matter. If the door needs drilling, welding, or changes to a multipoint system, get a qualified installer’s view before attempting the work. Do not force a bolt that meets resistance; correct alignment first.
Balance Features Against Maintenance and Backup
Smart locks add batteries, electronics, credentials, and sometimes network services to a mechanical door system. Check the power source, low-battery alerts, emergency power or key options, and the procedure for replacing batteries from indoors. Outdoor exposure can matter on metal gates or uncovered entryways, so confirm the product’s environmental limits instead of assuming an indoor-style lock can handle weather. A camera or face-recognition system may require more setup and power than a keypad deadbolt, while a basic keypad may be easier to maintain. Compare the likely upkeep with the convenience you expect to gain. For a door that must remain dependable during network or battery problems, prioritize a clear mechanical backup path.
Frequently Asked Questions
Can I install any smart deadbolt on a metal door?
No. A metal door may use a different thickness, backset, hole pattern, latch, or lock body from the standard deadbolt setup a product expects. Compare the manufacturer’s installation dimensions with your door before ordering. Also check whether the door has a narrow stile, multipoint hardware, or an existing mortise lock, since those can rule out a conventional deadbolt. If drilling or cutting seems necessary, ask the manufacturer or a locksmith whether the door can safely accept the change.
How do I tell whether a listed lock is for my metal entry door or for a gate or sliding door?
Start with the product’s stated hardware type and intended door style, not the word “smart” or its access features. The Eseesmart listing specifies a sliding-glass lock, while the EIYSIE and YUVEAI listings are gate locks; those are not direct substitutes for a standard entry deadbolt. Compare the latch or bolt shape, mounting method, door thickness range, and included components with your existing setup. When the listing leaves these details unclear, ask for installation drawings or dimensions before purchasing.
Should I choose fingerprint access or a keypad for a metal-door lock?
Choose based on who needs access and how the door is used. Fingerprint entry can reduce the need to carry a key or remember a code for regular household members, while a keypad can be easier to share with visitors or people who do not want to enroll a fingerprint. A model with both methods gives more flexibility but can involve extra setup and credential management. Neither option resolves a mechanical fit problem, so confirm the lock matches the door first. Keep a backup method available for low-battery or reader problems.
Is Wi-Fi necessary if my smart lock already has a keypad or fingerprint reader?
No; local keypad or fingerprint entry may cover everyday use without remote connectivity. Wi-Fi matters more if you want to check status or manage access while away, but the exact functions vary by model and app. Confirm whether remote features need a hub, an account, or a reliable signal at the door. Metal doors and nearby structures can weaken wireless reception, so test coverage near the lock location. If remote control is not a priority, a simpler connected setup may be easier to maintain.
What should I check before replacing a metal door’s existing lock?
Record the door thickness, backset, hole and mounting dimensions, lock type, handing, and the shape of the existing latch or bolt. Check whether the door has a mortise or multipoint system and whether the frame strike aligns with the new lock. Confirm that the package includes the parts you need, such as a handle set or strike plate, rather than assuming they are included. Ask the seller or manufacturer to confirm compatibility when dimensions are missing. For nonstandard doors or any job requiring metal cutting, get a locksmith’s assessment before installation.
Conclusion
For most buyers with a compatible standard deadbolt layout, I would start with the Philips 4200 Series Wi-Fi Smart Deadbolt with Keypad, Fingerprint Unlock, and Handle Set as the best overall pick for its mix of entry methods and coordinated hardware. The TEEHO TE001 is my best value-style choice for someone who wants keypad entry without biometric or app complexity, while the Philips Wi-Fi Front Lock Set makes more sense for buyers who want a deadbolt and two handles in one package. For beginners, I would favor a straightforward keypad setup such as TEEHO, provided its measurements match the door. The TianfuSpanda is the feature-heavy option for buyers seeking face recognition, a camera, and a doorbell, but it deserves extra scrutiny for installation and upkeep. Choose the Eseesmart for a compatible sliding-glass door or a listed gate lock for a gate—not as a substitute for a standard metal-door deadbolt. Before ordering any of them, verify the door preparation and lock-body fit; that check matters more than adding another access feature.
