The best smart locks with backup power keep you from being locked out when batteries run low, but backup methods differ: some rely on a physical key, while others offer emergency power contacts or other safeguards. My best overall pick is the eufy Security Smart Lock C220 for its fingerprint entry and connected features, while the Wyze Auto-Lock Bolt v2 stands out for including backup keys and the Tapo DL110 for fingerprint access with Wi-Fi. The key tradeoff is convenience versus resilience: keypad and fingerprint access can simplify daily entry, but they still depend on power and a compatible door. Before choosing, check whether the lock’s backup method is usable from outside and whether its fit suits your existing deadbolt. Read on for the full breakdown of all nine options and the buyer checks that matter most.

Key Takeaways
- Backup entry is not the same across this lineup: the Wyze Auto-Lock Bolt v2 explicitly includes backup keys, while buyers should verify the emergency-entry method for each other model before purchase.
- Fingerprint access is a major point of difference: the eufy C220, Tapo DL110, Philips fingerprint keypad model, and Wyze Bolt v2 offer biometric entry, while keypad-focused options suit households that prefer codes.
- Philips offers several distinct configurations: keypad-and-handle sets, a Wi-Fi deadbolt, and a weather-rated model are not interchangeable; choose by hardware format and entry needs, not brand name alone.
- Connectivity can add convenience but also reliance: Wi-Fi app and remote-control features may be useful away from home, while local keypad or key access matters if the network or phone is unavailable.
- Door compatibility can outweigh smart features: deadbolt dimensions, existing bore holes, handle configuration, and installation requirements should be checked before selecting any lock in this group.

More Details on Our Top Picks
Tapo Smart Wi-Fi Door Lock, Deadbolt, Fingerprint Recognition, DL110
The Tapo DL110 is the clearest fit here if avoiding routine battery swaps matters most: its rechargeable battery is rated for up to one year, longer than the Philips models’ six-month estimates and the eufy C220’s eight months. That advantage is paired with a physical backup key, keypad access, and fingerprint recognition, so a depleted battery is not the only fallback plan. The fingerprint reader’s stated 0.42-second response and capacity for 100 prints suit busy households sharing entry. Unlike the eufy Security Smart Lock C220, which includes AA batteries, the Tapo’s rechargeable setup means you need to plan for recharging rather than simply keeping replacement cells on hand. Its main limitation is that the supplied information specifies external installation only, and recognition can be affected by environmental conditions.
Pros:- Rechargeable battery rated for up to one year of use
- Fingerprint, keypad, app-connected Wi-Fi, Bluetooth, and backup-key access
- Stores up to 100 fingerprints for residents and regular guests
- Auto-lock, activity logs, and real-time alerts support access monitoring
Cons:- Rechargeable power requires advance planning to recharge rather than swapping in fresh AA batteries
- Fingerprint recognition may be less dependable in some environmental conditions
- Product information specifies external installation only
Best for: Households that want fingerprint entry and fewer scheduled battery replacements, and are comfortable recharging the lock when needed.
Not ideal for: Buyers who prefer replaceable AA batteries as their backup plan, or need a lock specified for installation beyond an exterior door.
- Access methods:Fingerprint, keypad passcodes, Wi-Fi, Bluetooth, voice assistants, backup keys
- Battery:Rechargeable; up to 1 year
- Fingerprint response:0.42 seconds
- Fingerprint capacity:Up to 100 fingerprints
- Connectivity:Wi-Fi and Bluetooth
- Smart-home compatibility:Amazon Alexa, Google Home, Samsung SmartThings
- Security features:Auto-lock, activity logs, real-time alerts
- Installation:Tools included; external installation
Our verdict“Choose the Tapo DL110 if a long-rated rechargeable battery and several entry backups matter more than the convenience of replaceable cells.”
Philips WiFi Keypad Door Lock with Handle, App Control Smart Deadbolt Lock
This Philips lock makes the most sense when weather resistance and a handle set are part of the buying decision, not just remote access. Its IP54 rating and stated operating range from -31°F to 150°F give it a more specific environmental case than the Philips DDL242X-15HW deadbolt, whose supplied details do not include a handle set. For backup power, it uses eight AA batteries and is rated for up to six months, while a physical key offers another way in if electronic access is unavailable. That schedule is shorter than the Tapo DL110’s stated rechargeable interval and the eufy C220’s eight-month estimate. The AA cells are not included, and Wi-Fi-dependent remote functions may be less useful where the connection is unreliable.
Pros:- IP54 weather-resistance rating and a wide stated temperature range
- Physical keys and passcodes provide alternatives to app access
- Includes two lever handles for a coordinated lock-and-handle installation
- Supports up to 100 passwords, auto-lock, and real-time notifications
Cons:- Eight AA batteries are required but not included
- Battery life is rated for up to six months, shorter than the Tapo DL110 and eufy C220 estimates
- Remote features rely on Wi-Fi, and installation still requires checking door dimensions
Best for: Homeowners replacing a compatible deadbolt and handles at an entry exposed to changing temperatures who want app access and a physical-key fallback.
Not ideal for: Buyers prioritizing long intervals between battery changes or a lock that arrives with its required AA batteries.
- Model:DDL242X-15HW-L
- Battery:8 AA batteries, not included; up to 6 months
- Access methods:App, passcodes, voice commands, physical keys
- Operating temperature:-31°F to 150°F (-35°C to 66°C)
- Door thickness:1-3/8 to 2 inches
- Cross bore compatibility:1-1/2 or 2-1/8 inches
- Included components:Lock and two lever handles
Our verdict“Pick this Philips model for a weather-exposed door where the included handles and physical-key backup outweigh the need for longer battery intervals.”
Philips Smart Lock, WiFi Keyless Deadbolt with App Control, Alexa & Google Support, IP54 Waterproof, Black
This Philips DDL242X-15HW is a straightforward choice for buyers who want app-connected keyless entry but do not need the handle set included with the other Philips model in this group. It accepts eight AA batteries for a stated six-month run and also supports physical keys, giving you a familiar fallback if the batteries run down. That makes the backup plan easy to understand, though it is less convenient than the Tapo DL110’s rechargeable battery and its longer stated interval. The IP54 rating and broad temperature range suit exposed residential doors, while passcodes and voice control add options for daily entry. The tradeoff is a recurring battery-replacement routine, and the supplied product details do not specify door-fit dimensions, so compatibility needs checking before purchase.
Pros:- Physical keys remain an entry backup alongside app, passcode, and voice access
- IP54 rating and stated operation across a wide temperature range
- Auto-lock, customizable passwords, and real-time security notifications
- Deadbolt-only package avoids paying for a handle set that may not be needed
Cons:- Requires eight AA batteries that are not included and are rated for up to six months
- Wi-Fi dependence can limit remote access when the network is unstable
- Supplied specifications do not list door-thickness or cross-bore compatibility
Best for: Buyers who want a weather-rated Wi-Fi deadbolt with AA-battery power and physical-key access, without needing replacement handles.
Not ideal for: Shoppers who want a longer stated battery interval, included batteries, or clearly listed door-fit dimensions before choosing a lock.
- Model:DDL242X-15HW
- Battery:8 AA batteries, not included; up to 6 months
- Access methods:App, voice commands, keys, passcodes
- Connectivity:Wi-Fi
- Operating temperature:-31°F to 150°F (-35°C to 66°C)
- Security features:Auto-lock, customizable passwords, real-time notifications
- Pressure resistance:2200 N
Our verdict“Choose this Philips deadbolt if you want a weather-rated, AA-powered lock with a physical-key fallback and do not need new handles.”
Philips WiFi Keypad Door Lock with Handle, Built-in WiFi, APP Remote Control, Voice & Fingerprint Unlock, Satin Nickel
Among these five, this Philips is the handle-set pick for buyers who want fingerprint entry alongside keypad and app control. Its supplied package includes two levers, a latch, and mounting hardware, while the Philips DDL242X-15HW-L offers a handle set but lists passcodes and keys rather than fingerprint unlocking. The tradeoff is that this model’s product details specify eight AA batteries but give no battery-life estimate or physical-key fallback. That leaves less certainty about backup planning than the Tapo DL110, which lists both a rechargeable battery interval and backup keys, or the eufy C220, which specifies its AA-battery life and includes keys. Check the stated door-thickness range before ordering, and plan to keep replacement batteries available.
Pros:- Combines fingerprint, keypad, voice, and app-based entry
- Built-in Wi-Fi supports remote management without a separate bridge listed
- Package includes two levers, latch assembly, screws, and installation hardware
- Auto-lock and access monitoring support routine door security
Cons:- Requires eight AA alkaline batteries that are not included
- Product details do not specify expected battery life
- No physical-key backup is listed in the supplied product information
Best for: Households replacing a compatible door lock and levers that want fingerprint access with built-in Wi-Fi remote management.
Not ideal for: Buyers who need a documented battery-life estimate or a listed physical-key backup as part of their power-failure plan.
- Model:DDL242X-1HW
- Battery:8 AA alkaline batteries, not included
- Access methods:Fingerprint, keypad, app, voice
- Connectivity:Built-in Wi-Fi
- Door thickness:1-3/8 to 1-3/4 inches (38 to 50 mm)
- Included components:Two door levers, latch assembly, mounting screws, installation hardware
- Smart features:Auto-lock, remote management, access monitoring
- Finish:Satin nickel
Our verdict“Choose this Philips if fingerprint access and a complete handle set are your priorities, but skip it if you need clearly documented battery endurance and key backup.”
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
The eufy Security Smart Lock C220 is the most ready-to-install AA-powered option in this group: it includes its eight batteries and two physical keys, rather than requiring a separate battery purchase like the Philips locks. Its stated eight-month battery life falls between the Philips models’ six-month estimates and the Tapo DL110’s up-to-one-year rechargeable rating. Built-in Wi-Fi avoids a separate bridge, and fingerprint, keypad, app, voice, and key access give households several ways to enter. The BHMA Grade 3 certification adds a stated security benchmark. Compared with the Tapo, though, the eufy uses replaceable AA cells rather than rechargeable power, and its fingerprint recognition may take time to improve as it learns. Check standard-deadbolt fit before buying.
Pros:- Includes eight AA batteries and two physical keys
- Built-in Wi-Fi provides remote access without a separate bridge
- Fingerprint, keypad, app, voice, and key entry offer several fallback routes
- BHMA Grade 3 certification and stated operating range of -22°F to 158°F
Cons:- Eight-month battery estimate is shorter than the Tapo DL110’s stated rechargeable interval
- Fingerprint recognition may be less consistent before its self-learning system adapts
- Requires a compatible standard deadbolt and specified bore size
Best for: Households seeking a Wi-Fi smart deadbolt that arrives with replacement-ready AA power, physical keys, and multiple entry methods.
Not ideal for: Buyers who want rechargeable power, a longer stated battery interval, or do not have a compatible standard deadbolt.
- Model:T8506
- Battery:8 AA batteries included; up to 8 months
- Unlock methods:Fingerprint, keypad, app, voice, physical key
- Wi-Fi:Built-in; no bridge required
- Fingerprint technology:Self-learning AI recognition
- Certification:BHMA Grade 3
- Operating temperature:-22°F to 158°F (-30°C to 70°C)
- Compatibility:Most standard deadbolts; bore size under 54 mm
Our verdict“Pick the eufy C220 if you want included AA batteries and physical keys with Wi-Fi and fingerprint access, rather than rechargeable power.”
Philips Wi-Fi Smart Deadbolt Lock, Keyless Entry Door Lock for Front Door
The Philips DDL242X-1HW suits households that want several ways in: fingerprint, passcode, physical key, voice command, and app control. Its fingerprint recognition is listed at 0.3 seconds, giving regular users a quick alternative to entering a code. Compared with the Wyze Lock Bolt v2, which pairs fingerprint access with specified backup keys and emergency USB-C power, the Philips description emphasizes a broader set of entry methods but provides less detail about backup power and battery life. Remote access and alerts can help when managing visitors, though remote features require Wi-Fi. Setup may also take more effort than a keypad-focused choice like the Yale Assure Lock 2. I’d rank it for access flexibility, not for buyers whose main priority is clearly documented battery endurance or emergency power.
Pros:- Offers fingerprint, passcode, key, voice, and app unlocking.
- Fingerprint recognition is specified at 0.3 seconds.
- Remote access and real-time alerts support off-site access management.
Cons:- Remote features depend on a Wi-Fi connection.
- Battery-life duration and backup-power details are not specified in the supplied product information.
- Setup may be complex for buyers who want a simple keypad installation.
Best for: Households with multiple users who want fingerprint, code, key, voice, and app entry options in one deadbolt.
Not ideal for: Buyers who need a clearly specified battery runtime or a documented emergency-power method before choosing a lock.
- Model:DDL242X-1HW
- Brand:PHILIPS
- Unlock methods:Fingerprint, passcode, key, voice command, and remote app control
- Fingerprint recognition:0.3 seconds
- Remote features:Remote access and real-time alerts; Wi-Fi required
- Voice assistant compatibility:Alexa and Google Assistant
- Included components:One door lock
Our verdict“Choose this Philips if you value several entry methods more than clearly documented battery runtime and emergency power.”
Yale WiFi Smart Lock Deadbolt with Keypad, Keyless Entry, Black Suede
The Yale Assure Lock 2 focuses on orderly access for busy households: its backlit keypad, unlimited user codes, schedules, and DoorSense make it easier to assign entry and check whether the door is shut. Auto-lock adds convenience when people forget to secure the door. Compared with the Tapo DL100, which gives a stated battery-life range and an emergency power option, the Yale’s supplied details don’t specify battery runtime or a backup-power method. That makes it a less certain choice for shoppers prioritizing power contingencies, despite its practical keypad-first design. Remote control and alerts also rely on Wi-Fi, and the product information does not name other smart-home integrations. I’d choose it for managing many users, but favor the Tapo or Wyze when explicit battery or emergency-power information carries more weight.
Pros:- Backlit keypad provides straightforward code entry.
- Supports unlimited user codes and schedules.
- DoorSense and auto-lock add door-status awareness and automatic locking.
- Includes a Wi-Fi module for app-based remote control.
Cons:- The supplied product details do not state battery life or a backup-power method.
- Full remote features require Wi-Fi.
- The supplied information does not confirm compatibility with other smart-home systems.
Best for: Families, shared homes, or landlords who need many individual entry codes and scheduled access.
Not ideal for: Buyers who want a stated battery runtime, a documented emergency-power option, or confirmed integration with other smart-home platforms.
- Model:YRD410-WF1-BSP
- Finish:Black Suede
- Entry:Keypad and Yale Access app
- User codes:Unlimited, with scheduling
- Door features:Auto-lock and DoorSense
- Included components:Lock, Wi-Fi smart module, deadbolt, latch plates, mounting hardware, DoorSense, and installation manual
- Warranty:Lifetime limited warranty on finish and mechanical parts; one year on electronics
Our verdict“Pick the Yale for flexible code management across a shared household, but look elsewhere if backup-power specifications are your deciding factor.”
Tapo Smart Wi-Fi Deadbolt Door Lock, Keyless Tactile Buttons, DL100
The Tapo DL100 is the clearest choice here for shoppers who want battery expectations spelled out: it runs on four AA batteries, with a stated estimate of up to 200 days in Wi-Fi mode or 300 days in Bluetooth mode. It also lists an emergency power option, a meaningful safeguard absent from the supplied Yale details. Keypad, Bluetooth, and remote app access offer flexibility, while compatibility with Alexa, Google Home, and SmartThings makes it a better fit for mixed smart-home setups than the Yale Assure Lock 2, whose listed integrations are unspecified. The tradeoff is that its certification is BHMA Grade 3, and battery replacement remains part of ownership. Buyers should also allow time for setup. I’d favor it for documented power planning, while the Wyze offers a stated runtime in months and backup keys.
Pros:- Specifies up to 200 days in Wi-Fi mode or 300 days in Bluetooth mode.
- Uses four included AA batteries and lists an emergency power option.
- Supports keypad, Bluetooth, and remote app access.
- Compatible with Alexa, Google Home, and Samsung SmartThings.
Cons:- Requires ongoing battery replacement and power monitoring.
- BHMA Grade 3 certification is not the highest grade available.
- Installation may require technical setup.
Best for: Smart-home owners who want a stated battery-life estimate, replaceable AA cells, and an emergency power option.
Not ideal for: Buyers seeking a higher-than-Grade-3 certification or a lock that avoids periodic battery replacement and setup work.
- Model:DL100
- Power source:Four AA batteries, included
- Battery life:Up to 200 days in Wi-Fi mode; up to 300 days in Bluetooth mode
- Emergency power:Emergency power option listed
- Connectivity:Wi-Fi and Bluetooth
- Smart-home compatibility:Alexa, Google Home, and Samsung SmartThings
- Certification:BHMA Grade 3
- Outdoor dimensions:5.88 x 2.65 x 2.2 inches
Our verdict“Choose the Tapo DL100 if clear battery estimates and an emergency power option matter more than a higher security grade.”
Wyze Auto-Lock Bolt v2 Fingerprint Smart Lock with Wi-Fi, Keyless Entry, Auto-Lock, and Backup Keys
The Wyze Lock Bolt v2 makes backup access unusually explicit: alongside up to eight months of battery life, it includes backup keys and emergency USB-C power. That combination gives buyers more than one fallback if the batteries run low, a stronger power-focused case than the Philips DDL242X-1HW, whose supplied details omit both runtime and emergency-power information. Fingerprint unlocking takes under half a second, with keypad codes and Wi-Fi app control as alternatives. Its IP53 weather resistance is a practical limit, though: it is not described as fully weatherproof, so exposed installations deserve extra care. Battery life can vary with use, and remote features depend on Wi-Fi. I’d pick Wyze for layered contingency access; choose the Tapo DL100 instead if its stated Wi-Fi-versus-Bluetooth battery estimates and named smart-home integrations suit your priorities better.
Pros:- Lists up to eight months of battery life.
- Includes backup keys and emergency USB-C power.
- Fingerprint recognition unlocks in under 0.5 seconds.
- Adds keypad codes, Wi-Fi app control, and auto-lock.
Cons:- IP53 weather resistance is not full weatherproofing.
- Battery life varies with use.
- Remote app features require Wi-Fi.
Best for: Homeowners who want fingerprint entry plus several fallbacks, including backup keys and emergency USB-C power.
Not ideal for: People installing a lock in a highly exposed location or those who need battery life to remain consistent regardless of usage.
- Model:WLCKB2
- Power source:Eight AA batteries included
- Battery life:Up to eight months
- Emergency power:USB-C emergency power
- Backup entry:Backup keys
- Unlock methods:Fingerprint, keypad, and app control
- Fingerprint unlocking:Under 0.5 seconds
- Weather resistance:IP53
Our verdict“Choose the Wyze if you want multiple ways to regain entry when battery power runs low, and your installation is not highly exposed to weather.”
How We Picked
I compared these nine locks around the central promise of this roundup: keeping a usable path into the home when normal electronic operation is interrupted. I looked at the backup method disclosed for each model, including whether a physical key is included or whether buyers need to confirm another emergency-power or mechanical-entry procedure. I also weighed daily entry options such as fingerprints, keypads, app control, and voice-assistant support, since a backup plan is only useful if the lock fits how a household actually enters.
The ranking favors locks with clear, practical entry options and a strong balance of everyday convenience and fallback access. Models with richer features do not automatically rank higher: installation format, weather protection, connectivity dependence, and uncertainty around the backup procedure affect who should choose them. Since exact emergency-power details can vary by product version and setup, I treat backup claims cautiously and recommend checking the current manufacturer instructions before buying.
Factors to Consider When Choosing Best Smart Locks With Backup Power
Backup power is only one part of a reliable entry plan. I would match the lock to the door, the people who use it, and the failure modes you want to guard against before comparing app features.
Separate Battery Backup From Backup Entry
A lock may have replaceable batteries without giving you a way to operate it after those batteries are fully depleted. Check whether the product provides a physical key, external emergency-power contacts, or another stated recovery procedure. A key is useful only if you keep it somewhere accessible outside the locked home, while an emergency battery contact requires you to know what battery and terminals the manufacturer specifies. Do not assume that an app, keypad, or fingerprint reader will work during a power failure; those are electronic functions. Read the exact instructions for the model and version you plan to buy, since similar-looking locks can use different fallback methods.
Plan for More Than a Power Outage
Households can lose access for reasons beyond depleted batteries: a phone may be dead, Wi-Fi may be down, a fingerprint may not register, or a code may be forgotten. A reliable setup pairs the lock’s built-in fallback with a separate household plan, such as a securely stored spare key or a second authorized code. Think through who needs access, including children, guests, caregivers, and anyone who may struggle with small buttons or app setup. A lock with several electronic entry methods can still leave a gap if they all depend on the same battery. Choose a backup path that remains available during the specific failures you are most concerned about.
Check Door Fit Before Comparing Features
Smart deadbolts can differ in required door thickness, backset, bore-hole dimensions, and compatibility with an existing handle or latch. A handle-and-lock set may call for a different replacement approach than a deadbolt-only model. Measure the door and inspect the current hardware before ordering, then compare those measurements with the manufacturer’s installation requirements. Also check whether the lock supports the door’s handing and whether the bolt moves freely; a tight or misaligned deadbolt can drain batteries faster and interfere with operation. If the door needs modifications, installation effort may matter more than an extra app feature.
Decide How Much You Depend on Wi-Fi
Wi-Fi can enable remote control, notifications, and integrations, but it adds setup steps and makes some conveniences dependent on the home network. Ask whether you need to lock or check the door while away, or whether local keypad, fingerprint, and key access cover your routine. Remote access features may also depend on an account, app permissions, and a stable connection, so they should not be treated as the emergency plan. If the household wants straightforward entry, prioritize controls that work at the door without a phone. If remote management matters, keep local access methods available as a separate route.
Match the Entry Method to the Household
Fingerprints can reduce code sharing and speed up entry, but recognition may be less convenient for wet, dirty, or injured fingers. Keypads work for multiple people and visitors, though codes need thoughtful management and can be observed if entered in public view. Physical keys are familiar and independent of electronics, but they require careful storage and can be misplaced. App access can help manage users, yet it may add friction for someone who does not carry a charged phone. When several people use the door, favor a lock that offers more than one practical everyday method rather than choosing by a single headline feature.
Treat Weather and Maintenance as Reliability Factors
Outdoor exposure can affect keypad responsiveness, battery life, and the long-term condition of a lock. Check any stated weather-protection rating and compare it with the door’s exposure to rain, snow, and direct sun; a rating does not mean every installation location is equally protected. Build a battery-check routine into seasonal home maintenance instead of waiting for a warning at the door. Keep the manufacturer’s specified battery type on hand and follow its guidance on replacement, since unsuitable batteries can create performance problems. A model with a clear maintenance process may be a better fit than one with more features but less familiar upkeep.
Frequently Asked Questions
Which lock in this roundup clearly includes a physical backup key?
The Wyze Auto-Lock Bolt v2 is identified as including backup keys, making it the clearest choice here for buyers who want a mechanical fallback. A physical key can help when electronic entry is unavailable, but it only helps if a key is accessible from outside the home. Check how many keys are supplied and whether additional copies can be made. For the other models, confirm the exact included backup method in the current product documentation rather than assuming a key or emergency-power feature is present.
Will a smart lock still work if my home Wi-Fi goes down?
Wi-Fi loss does not necessarily mean the door lock itself stops operating, but it can interrupt remote app functions and connected features. Local methods such as a keypad, fingerprint reader, or physical key may remain available, depending on the model and its power state. Check the manufacturer’s description to separate local entry from features that require internet access. If you need access during a network outage, choose a lock with a local method you can use without your phone or router.
Is fingerprint entry a dependable backup method?
Fingerprint entry is another way to access a powered lock, not a substitute for a dead-battery recovery plan. Recognition can also be less convenient when a finger is wet, dirty, injured, or difficult for the sensor to read. A keypad or key gives you a different route if biometrics fail, so having multiple entry methods is more useful than relying on fingerprint access alone. Check how the lock behaves at low battery and what fallback the manufacturer specifies.
Should I choose a handle-and-lock set or a deadbolt-only model?
A handle-and-lock set may suit a door where you plan to replace coordinated hardware, while a deadbolt-only lock can be a simpler match for an existing handle. The two formats may differ in installation requirements, included components, and compatibility with your door. Measure the existing hardware and confirm the required bore holes, backset, and door thickness before buying. Do not select a handle set just for its bundled appearance if the lock’s backup method or fit is less suitable for your needs.
What should I do before relying on a new lock as my only way into the house?
Install the lock, test every entry method, and follow the manufacturer’s procedure for low-battery or emergency operation before removing your old hardware or changing household routines. Confirm whether a physical key, external power source, or another recovery method is actually available on your model. Keep a backup key or required emergency battery somewhere accessible but secure, and make sure other household members know how to use it. Set a battery reminder and verify that the deadbolt moves smoothly with the door closed, not only while the door is open.
Conclusion
For the broadest mix of smart entry options, I would start with the eufy Security Smart Lock C220 as my best overall pick, while remembering to verify its exact emergency-entry procedure. The Wyze Auto-Lock Bolt v2 is my best fit for buyers who specifically want backup keys, and the Tapo DL100 is a value-minded option for households that prefer tactile keypad buttons over fingerprint entry. Beginners who want a familiar keypad-and-handle format can compare the Philips WiFi Keypad Door Lock with Handle models, choosing the configuration that matches their door. For premium-feature seekers, the Philips fingerprint keypad model adds several entry routes, while buyers needing weather protection should look at the Philips model rated IP54. My final choice would come down to door fit and a confirmed fallback plan: choose the lock whose backup method you can actually use when the battery, phone, or network is unavailable.
