The best smart locks with backup power keep an entry option available when batteries run low or a preferred access method is unavailable. My best overall pick is the Wyze Auto-Lock Bolt v2, which pairs fingerprint and Wi-Fi access with backup keys; the eufy Security Smart Lock C220 is a standout for fingerprint entry, while the TEEHO TE001 suits buyers who want a simpler keypad and keyed fallback. The main tradeoff is between connected features and simpler, less app-dependent access, with fit, backup method, and handle style also shaping the choice. Check your door and preferred entry methods before choosing. Read on for the full comparison and practical guidance.
Complete the kit
Key Takeaways
- Wyze Auto-Lock Bolt v2 leads this lineup for access variety: it combines fingerprint and Wi-Fi features with backup keys, making it a strong all-round choice for buyers who want more than one way in.
- Backup methods differ across the shortlist: several models explicitly include a physical key, while keypad-only designs such as the Tapo DL100 put more weight on having working batteries and remembering a code.
- The TEEHO TE001 appears in three finishes: bronze, satin nickel, and matte black offer a way to match hardware, but the finish variants do not provide three distinct feature sets.
- Two Philips keypad-with-handle listings target a different installation need: they combine a lock and handle, unlike deadbolt-only choices, so buyers should check their existing door hardware before comparing features.
- Fingerprint entry is a recurring strength, not a substitute for every backup: Wyze, Tapo DL110, eufy C220, and Philips models offer fingerprint access, but buyers should still confirm the exact key, power-loss, and connectivity fallback for the selected model.

More Details on Our Top Picks
Wyze Auto-Lock Bolt v2 Fingerprint Smart Lock with Wi-Fi, Keyless Entry, Auto-Lock, and Backup Keys
The Wyze Bolt v2 is my strongest all-around pick for backup access because it pairs eight AA batteries with physical backup keys and emergency USB-C power. That gives buyers more than one fallback if the batteries run down, while its fingerprint reader offers a quick everyday entry method without a key or code. Wi-Fi adds remote management, though those app features depend on a working connection. Compared with the Tapo DL110, Wyze lists a clearer set of emergency entry options, while Tapo offers a rechargeable battery and broader stated smart-home compatibility. Wyze’s tradeoffs are its battery life of up to eight months and IP53 weather resistance, which calls for more sheltered placement than a more weather-resistant lock. Choose it for layered access, not maximum battery endurance.
Pros:- Backup keys and emergency USB-C power provide alternatives if the batteries are depleted.
- Fingerprint unlocking is specified at under half a second.
- Wi-Fi and app control support remote management.
- Adaptive fingerprint recognition is designed to improve with use.
Cons:- Battery life is listed as up to eight months and can vary with use.
- IP53 weather resistance is not a fully weatherproof rating.
- Remote features require Wi-Fi.
Best for: Households that want fingerprint entry plus physical keys and emergency USB-C power as separate ways back in.
Not ideal for: Buyers prioritizing a longer stated battery interval or a lock exposed to heavy weather; its battery estimate is up to eight months and its rating is IP53.
- Brand:WYZE
- Model:WLCKB2
- Connectivity:Wi-Fi
- Power:8 AA batteries
- Stated battery life:Up to 8 months
- Weather resistance:IP53
- Access methods:Fingerprint, keypad, app control, backup keys
- Emergency power:USB-C
Our verdict“Choose the Wyze Bolt v2 if you want several distinct backup entry methods alongside fast fingerprint access.”
Yale WiFi Smart Lock Deadbolt with Keypad, Keyless Entry, Black Suede
The Yale Assure Lock 2 suits homes where reliable access for many people matters more than fingerprint entry. Its keypad, unlimited user codes, schedules, and real-time alerts make it easier to give guests or household members individual access and manage when codes work. DoorSense and automatic locking add a check on whether the door is shut and locked. Compared with the Wyze Bolt v2, Yale emphasizes code administration rather than multiple biometric and emergency-power methods; the supplied product details do not specify a battery type, battery life, or external backup-power option. That makes it harder to judge against a roundup focused on backup power. Its Wi-Fi module supports remote app control, but the product data does not identify smart-home integrations. I’d choose it for code-heavy households, not buyers who want a clearly documented power fallback.
Pros:- Unlimited user codes support access for a large household or rotating visitors.
- Schedules help limit when keypad codes can be used.
- DoorSense and auto-lock add door-status and locking functions.
- Includes a Wi-Fi smart module for app-based remote control.
Cons:- The provided specifications do not state battery life, battery type, or a backup-power method.
- Full remote features require Wi-Fi.
- The supplied product information does not list compatibility with other smart-home systems.
Best for: Families, hosts, or shared homes that need many individually managed keypad codes, schedules, and access alerts.
Not ideal for: Buyers who require a specified battery runtime or documented emergency power source; those details are absent from the supplied product information.
- Brand:Yale Security
- Model:YRD410-WF1-BSP
- Included connectivity component:Wi-Fi smart module
- Entry method:Keypad and smartphone app
- User codes:Unlimited
- Access management:Schedules and real-time alerts
- Door features:Auto-Unlock and DoorSense
- Warranty:Lifetime limited warranty on finish and mechanical components; one year on electronics
Our verdict“Pick the Yale if flexible code management is your priority, but choose a model with documented emergency power if battery fallback is the deciding factor.”
Philips WiFi Keypad Door Lock with Handle, Built-in WiFi, APP Remote Control, Voice & Fingerprint Unlock, Satin Nickel
This Philips pick stands out for buyers who want a handle-style lock with fingerprint, keypad, and app access in one package. Its listed battery setup is eight AA alkaline batteries, but the batteries are not included, so buyers need to provide them before installation. The product data does not specify battery life or a separate emergency-power input, making its backup-power story less complete than the Wyze Bolt v2, which lists backup keys and USB-C emergency power. Compared with the Yale Assure Lock 2, Philips adds fingerprint access and a handle, while Yale’s supplied details are stronger on user-code scheduling. Door fit also needs a check: it supports thicknesses from 1-3/8 to 1-3/4 inches. I’d favor it when the lever format and varied entry methods fit the door, but not when documented battery endurance is the main criterion.
Pros:- Combines fingerprint, keypad, app, and voice-command access.
- Built-in Wi-Fi supports remote app management.
- Lever-style hardware may suit doors where a handle is preferred over a standalone deadbolt.
- Fits doors 1-3/8 to 1-3/4 inches thick.
Cons:- Eight AA alkaline batteries are required and not included.
- The supplied specifications do not state battery life or an emergency-power method.
- Door thickness must be checked for compatibility before purchase.
Best for: Homeowners replacing a lever-style entry set who want fingerprint and keypad access with app-based remote management.
Not ideal for: Buyers who want included batteries, a stated battery runtime, or clearly documented emergency power; those details are missing or require separate purchase.
- Brand:PHILIPS
- Model:DDL242X-1HW
- Connectivity:Built-in Wi-Fi
- Access methods:Fingerprint, keypad, app, voice commands
- Battery requirement:8 AA alkaline batteries
- Batteries included:No
- Compatible door thickness:1-3/8 to 1-3/4 inches (38 to 50 mm)
- Included hardware:Door levers, latch assembly, mounting hardware, and user manual
Our verdict“Choose this Philips model for a lever-style setup and several access methods, not for a well-documented battery backup plan.”
Teeho TE001 Keyless Entry Deadbolt with Keypad for Front Door, Bronze
The Teeho TE001 takes a simpler route to backup readiness: it runs on four AA batteries and lists battery life of up to 365 days, so routine battery changes may be less frequent than with the Wyze Bolt v2’s stated eight-month maximum. It is a keypad deadbolt rather than a connected lock, with capacity for 20 access codes and a one-time guest code. That keeps access straightforward, but there is no app, fingerprint reader, or documented emergency USB power in the supplied details. Compared with the Tapo DL110, Teeho gives up rechargeable power and connected activity tools in exchange for a simpler, longer stated battery interval. It also has an IP54 rating and low-battery alerts, though its 2-1/8-inch door-hole requirement and reset step make fit and setup worth checking before installation.
Pros:- Battery life is specified as up to 365 days with four AA batteries.
- Supports 20 access codes plus a one-time guest code.
- Low-battery alerts give notice before the batteries run out.
- IP54 weather resistance and automatic locking suit front-door use.
Cons:- Four AA batteries are not included.
- The supplied details do not list an emergency power input or physical backup key.
- Requires a 2-1/8-inch door hole and a reset for first use.
Best for: Buyers seeking a straightforward keypad deadbolt with a long stated battery interval and guest-code access, without needing app control.
Not ideal for: Smart-home users who want remote control, fingerprint unlocking, or documented emergency power, or anyone with an incompatible 38 mm door hole.
- Model:TE001
- Material:Aluminum alloy
- Battery type:4 AA batteries
- Stated battery life:Up to 365 days
- Weather resistance:IP54
- Access-code capacity:20 codes plus one-time guest code
- Door-hole compatibility:2-1/8 inches (54 mm)
- Warranty:2 years
Our verdict“Choose the Teeho TE001 if you want a simple keypad lock with a long stated battery interval and can do without connected controls.”
Tapo Smart Wi-Fi Door Lock, Deadbolt, Fingerprint Recognition, DL110
The Tapo DL110 is the clearest choice here for buyers who prefer rechargeable power over stocking disposable batteries: its battery is rated for up to a year, and the lock supports fingerprint, keypad, Wi-Fi, and Bluetooth access. A stated 0.42-second fingerprint read makes quick entry the everyday draw, while storage for up to 100 fingerprints can suit a busy household. Compared with the Wyze Bolt v2, Tapo lists broader smart-home compatibility, including Alexa, Google Home, and SmartThings, but Wyze more explicitly names backup keys and USB-C emergency power. The Tapo’s supplied information calls out backup keys but does not detail an external power fallback if its rechargeable battery is depleted. Battery life can vary, and the product is specified for external installation only, so check placement before choosing it.
Pros:- Rechargeable battery is rated for up to one year of use.
- Fingerprint, keypad, Wi-Fi, Bluetooth, and backup keys provide multiple access methods.
- Stores up to 100 fingerprints and reads a fingerprint in a stated 0.42 seconds.
- Lists compatibility with Alexa, Google Home, and Samsung SmartThings.
Cons:- The supplied product details do not specify an external emergency-power input.
- Battery life and fingerprint recognition can vary with use and conditions.
- Specified for external installation only.
Best for: Smart-home households that want rechargeable power, fast fingerprint entry, and access for many residents or guests.
Not ideal for: Buyers who need an explicit external emergency-power method or want to install a lock on an interior-facing door; the listed installation is external only.
- Model:DL110
- Battery type:Rechargeable
- Stated battery life:Up to 1 year
- Access methods:Fingerprint, keypad passcodes, Wi-Fi, Bluetooth, voice assistants, backup keys
- Fingerprint recognition speed:0.42 seconds
- Fingerprint storage:Up to 100 fingerprints
- Smart-home compatibility:Amazon Alexa, Google Home, Samsung SmartThings
- Security features:Auto-lock, activity logs, real-time alerts
Our verdict“Pick the Tapo DL110 if rechargeable power and smart-home integrations matter most, but favor Wyze if USB-C emergency power is a must.”
Tapo Smart Wi-Fi Deadbolt Door Lock, Keyless Tactile Buttons, DL100
The Tapo DL100 is the strongest fit here for buyers who want remote control and smart-home integration alongside a backup way to get in. It runs on four replaceable AA batteries and offers keypad, Bluetooth, and app unlocking, so a Wi-Fi interruption does not remove every electronic access option. Its stated battery life reaches 200 days on Wi-Fi or 300 days on Bluetooth, giving buyers a useful estimate for planning replacements. Compared with the keypad-only TEEHO TE001, the Tapo adds remote access and voice-assistant compatibility, but also brings more setup and power-management complexity. Its emergency power option is a plus, though the supplied details do not specify the method. BHMA Grade 3 is a practical residential rating, not a higher security grade.
Pros:- Keypad, Bluetooth, and remote app access provide several entry options.
- Four replaceable AA batteries and an emergency power option address depleted-battery lockouts.
- Works with Alexa, Google Home, and Samsung SmartThings.
- Rated for a broad temperature range of -22°F to 158°F.
Cons:- Wi-Fi use has a shorter stated battery life than Bluetooth use.
- Installation and smart-home setup may require technical effort.
- BHMA Grade 3 is not the highest available grade.
Best for: Households using Alexa, Google Home, or SmartThings that want remote access plus replaceable-battery backup.
Not ideal for: Buyers seeking a simple keypad-only lock, or those who prefer a higher certification grade and minimal app setup.
- Power:4 AA batteries, included
- Battery life:Up to 200 days in Wi-Fi mode; up to 300 days in Bluetooth mode
- Connectivity:Wi-Fi and Bluetooth
- Unlock methods:Keypad, Bluetooth, and remote app control
- Smart-home compatibility:Alexa, Google Home, and Samsung SmartThings
- Certification:BHMA Grade 3
- Outdoor dimensions:5.88 x 2.65 x 2.2 inches
- Temperature range:-22°F to 158°F
Our verdict“Choose the DL100 if remote access and smart-home links matter more than the simpler operation of the keypad-only TEEHO TE001.”
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
The satin-nickel TE001 suits buyers who want basic keypad access with infrequent battery changes, rather than app-based controls. Its four AA batteries are rated for up to 365 days, and low-battery alerts give owners a warning to replace them before power runs out. There is no stated emergency power input, so the included battery-life estimate and alerts matter more here than on the Tapo DL100, which adds app and Bluetooth access. The TEEHO keeps operation straightforward with 20 user codes, a one-time guest code, and automatic locking. That simplicity comes with limits: it lacks remote access, and the batteries are not included. Before buying, check the door bore size; this version is listed for 2-1/8-inch holes and is not compatible with 38 mm holes.
Pros:- Up to 365 days of stated battery life from four AA batteries.
- Supports 20 user codes and a one-time guest code.
- Low-battery alerts provide time to replace cells.
- IP54 weather resistance and a two-year warranty.
Cons:- Four AA batteries are not included.
- No app, Wi-Fi, or Bluetooth access is listed.
- Door-hole compatibility is limited to the specified 2-1/8-inch size.
Best for: Owners who want a weather-resistant keypad deadbolt, multiple household codes, and a long stated battery interval without smart-home features.
Not ideal for: Buyers who need remote unlocking, included batteries, or a lock that fits a 38 mm door hole.
- Power:4 AA batteries, not included
- Battery life:Up to 365 days
- Access codes:20 user codes, including one-time guest code
- Weather resistance:IP54
- Material:Aluminum alloy
- Locking:Automatic locking with manual override
- Door compatibility:Suitable for 2-1/8-inch (54 mm) door holes; not compatible with 38 mm holes
- Warranty:2 years
Our verdict“Pick this TE001 over the Tapo DL100 if long battery intervals and keypad simplicity matter more than remote access.”
Philips Wi-Fi Smart Deadbolt Lock, Keyless Entry Door Lock for Front Door
This Philips lock is the pick for buyers who want fingerprint entry plus remote access in one deadbolt. Its listed methods include fingerprint, passcode, physical key, voice commands, and app control; the claimed 0.3-second fingerprint recognition could make routine entry quicker than typing a code. Against the eufy Security Smart Lock C220, it offers a similar biometric-and-app approach, but eufy provides more concrete backup-power details, including eight AA batteries and an eight-month estimate. Philips lists no battery type, battery-life figure, or emergency power method, leaving a meaningful gap for a roundup centered on backup power. Wi-Fi is also needed for remote features, and setup may take more effort than the keypad-only TEEHO TE001.
Pros:- Offers fingerprint, passcode, physical-key, voice, and app access.
- Fingerprint recognition is listed at 0.3 seconds.
- Real-time alerts and remote access support off-site monitoring.
- Works with Alexa and Google Assistant.
Cons:- Battery type and expected battery life are not specified in the supplied product data.
- No emergency power method is specified.
- Remote app features depend on Wi-Fi, and setup may be complex.
Best for: Households prioritizing quick fingerprint entry and remote app access that can verify power details with the seller before purchase.
Not ideal for: Buyers who need a clearly stated battery life, battery type, or emergency power procedure before choosing a lock.
- Model:DDL242X-1HW
- Unlock methods:Fingerprint, passcode, physical key, voice commands, and app control
- Fingerprint recognition:0.3 seconds, as listed
- Connectivity:Wi-Fi
- Remote features:Remote access and real-time alerts
- Voice compatibility:Alexa and Google Assistant
- Battery information:Battery type and battery life not specified in supplied data
Our verdict“Choose this Philips for biometric convenience only if its battery and emergency-entry details meet your backup-power needs.”
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
The eufy C220 earns this spot by pairing several ways to enter with unusually clear battery information: eight AA batteries are included, with a stated life of up to eight months. A physical key provides a separate backup if the batteries run down, while built-in Wi-Fi avoids the need for a bridge for remote access. That makes its backup story more concrete than the Philips DDL242X-1HW, whose supplied details omit battery life and battery type. The tradeoff is a larger battery set to maintain, and actual life can vary with use. Its fingerprint reader may also take time to recognize a household’s prints consistently. For buyers who prefer keypad-only simplicity, the TEEHO TE001 has a much longer stated battery interval, though it lacks the C220’s remote and biometric access.
Pros:- Includes eight AA batteries and lists up to eight months of battery life.
- Physical key gives an independent entry option if battery power is exhausted.
- Built-in Wi-Fi enables remote access without a separate bridge.
- Fingerprint, keypad, app, and voice controls provide varied entry choices.
Cons:- Uses eight AA batteries, and battery life varies with usage.
- Requires compatibility with a standard deadbolt and specified bore size.
- Fingerprint recognition may be less consistent at first.
Best for: Households wanting fingerprint, keypad, app, and physical-key access with included batteries and a stated replacement interval.
Not ideal for: Buyers who want the fewest batteries to manage, a longer stated interval between changes, or a lock for a nonstandard deadbolt.
- Power:8 AA batteries, included
- Battery life:Up to 8 months
- Unlock methods:Fingerprint, keypad, app, voice, and physical key
- Connectivity:Built-in Wi-Fi; no bridge required
- Certification:BHMA Grade 3
- Compatibility:Most standard deadbolts; bore size under 54 mm
- Operating temperature:-22°F to 158°F
- Included backup hardware:2 physical keys
Our verdict“Choose the C220 for the clearest mix of included battery backup, physical-key access, and connected entry in this group.”
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Matte Black
The matte-black TE001 is a practical choice for buyers who need keypad access for household members and occasional guests, without the added battery demands of Wi-Fi or fingerprint features. It supports 20 user codes and a one-time guest code, plus automatic locking with an adjustable delay. Its stated battery life of up to 365 days is longer than the eufy C220’s eight-month estimate, but the TEEHO needs four AA batteries that are not included and has no listed emergency power input. The C220 is the better match for remote access and multiple unlocking methods; this TE001 keeps the routine simpler and less connected. Check door fit before ordering, since it does not suit 38 mm holes, and note its ANSI Grade 3 security level.
Pros:- Provides 20 user codes and a one-time guest code.
- Up to 365 days of stated battery life, with low-battery indication.
- Adjustable automatic locking can reduce the chance of leaving the door unlocked.
- IP54 water resistance and aluminum-alloy construction.
Cons:- Four AA batteries are not included.
- No Wi-Fi, app, or fingerprint unlocking is listed.
- Limited to ANSI Grade 3 and incompatible with 38 mm door holes.
Best for: Renters, households, or garage users who need multiple keypad codes and a temporary guest code without app-based control.
Not ideal for: Buyers seeking remote unlocking, fingerprint entry, included batteries, or compatibility with a 38 mm door hole.
- Model:TE001
- Power:4 AA batteries, not included
- Battery life:Up to 365 days
- Access codes:20 user codes, including one-time guest code
- Water resistance:IP54
- Material:Aluminum alloy
- Locking features:Automatic lock and one-touch auto-lock
- Security grade:ANSI Grade 3
Our verdict“Choose the matte-black TE001 over the eufy C220 if guest codes and long stated battery life matter more than remote or fingerprint access.”
Philips WiFi Keypad Door Lock with Handle, App Control Smart Deadbolt Lock
The Philips WiFi Keypad Door Lock with Handle suits buyers who want to replace a handle and deadbolt together while keeping several ways to get inside. Its key backup matters if the eight AA batteries run down, and passcodes provide key-free entry for household members or guests. Remote app control and voice-command support add convenience, though those connected features depend on a reliable WiFi connection. Compared with the Philips Smart Lock B0FC6RBHJ5, this version includes two lever handles, making it the more suitable choice when the existing handle also needs replacement; the other model is a simpler deadbolt-only package. The tradeoff is battery upkeep: the stated life is up to six months, and batteries are not included. Its broad door-thickness range helps with fit, but installation may still challenge some buyers.
Pros:- Physical key provides an entry option if battery power is depleted.
- Includes two lever handles as well as the lock, unlike the deadbolt-only Philips Smart Lock B0FC6RBHJ5.
- Supports passcodes, app control, and Alexa or Google Assistant voice commands.
- Accepts up to 100 passwords and offers auto-lock and real-time notifications.
Cons:- Requires eight AA batteries, which are not included, with stated battery life of up to six months.
- Remote app features depend on a stable WiFi connection.
- Replacing a handle and deadbolt can make installation more involved than fitting a deadbolt-only lock.
Best for: Homeowners replacing both a standard deadbolt and lever handles who want app access, keypad codes, and a physical key backup.
Not ideal for: Buyers seeking a lock with rechargeable or included backup power, or those whose entry has unreliable WiFi and who depend on remote access.
- Battery type:8 AA batteries, not included
- Stated battery life:Up to 6 months
- Unlocking methods:App, passcodes, voice commands, and physical keys
- Password capacity:Up to 100 passwords
- Door thickness:1-3/8 to 2 inches
- Cross bore compatibility:1-1/2 or 2-1/8 inches
- Weather protection:IP54
- Included components:Door lock and 2 lever handles
- Warranty:2 years
Our verdict“Choose this Philips if you need a handle-and-deadbolt set with a physical key fallback, but skip it if you want battery backup beyond replaceable AA cells.”
Philips Smart Lock, WiFi Keyless Deadbolt with App Control, Alexa & Google Support, IP54 Waterproof, Black
This Philips deadbolt is a straightforward fit for buyers who want connected entry without replacing the door handle. Its physical key backup gives it a useful fallback if the eight AA batteries are exhausted, while passcodes offer everyday keyless access. App control, notifications, and Alexa or Google Assistant support add remote convenience, but they rely on WiFi; the lock’s stated six-month battery life also means regular battery changes are part of ownership. Compared with the Philips WiFi Keypad Door Lock with Handle, this model has a simpler deadbolt-only scope, so it makes more sense when the existing handle is staying in place. The tradeoff is that the supplied information lists no lever handles, and buyers who need to replace both pieces should choose the handle-set version instead. IP54 protection supports outdoor use, though it does not remove the need for battery maintenance.
Pros:- Physical key offers a fallback when the AA batteries are depleted.
- Keypad, app, and voice-control options support different household access preferences.
- Auto-lock and real-time notifications add entry oversight without replacing the handle.
- IP54 rating and a stated operating range from -31°F to 150°F support varied weather conditions.
Cons:- Eight AA batteries are not included and have a stated life of about six months.
- App-based remote control and notifications depend on WiFi stability.
- Does not include lever handles, unlike the Philips WiFi Keypad Door Lock with Handle.
Best for: People keeping their existing door handle who want keypad and app access with a physical key available as a battery-failure fallback.
Not ideal for: Buyers replacing a complete handle-and-deadbolt set, or anyone wanting rechargeable backup power or remote operation independent of WiFi.
- Battery type:8 AA batteries, not included
- Stated battery life:6 months
- Unlocking methods:App, passcodes, voice commands, and physical keys
- Connectivity:WiFi
- Weather protection:IP54
- Operating temperature:-31°F to 150°F (-35°C to 66°C)
- Pressure resistance:2200 N
- Included components:1 door lock
Our verdict“Pick this deadbolt if your handle is staying and you want a physical-key fallback, but choose the Philips handle-set model if you need both door components replaced.”
How We Picked
I ranked these locks around the question behind this roundup: what happens when the preferred way of unlocking a door is unavailable? I gave weight to the stated fallback options, including physical keys and keypad entry, and to how those options complement app, Wi-Fi, and fingerprint features. I also considered whether a product is a deadbolt-only replacement or a lock-and-handle set, since that changes installation fit and the scope of the upgrade.
The order favors models with a useful mix of access methods and a clear role for different households, then distinguishes simpler keypad options from connected, feature-rich alternatives. I treated finish-only versions of the same TEEHO model as one underlying design rather than separate winners. Product names alone do not establish every detail of emergency power behavior, so buyers should verify the exact model’s battery type, low-battery warning, external power provision, and keyed fallback before purchase.

Factors to Consider When Choosing Best Smart Locks With Backup Power
Backup power can mean different things: a physical key that bypasses electronics, a way to power the lock temporarily from outside, or simply batteries that can be replaced before they run out. I recommend deciding which failure you most want to guard against before comparing app features. These checks can also prevent buying a lock that works well on paper but does not suit your door or household.
Decide What Backup Means for Your Household
Do not assume every advertised backup feature solves the same problem. A physical key can help if batteries or electronics fail, but it will not help if nobody has the key nearby. A temporary external power connection, when a specific model supports one, can help with a depleted battery but may still depend on the lock’s electronics. A keypad gives you a non-phone entry route, yet it still relies on working batteries. Choose a primary fallback and a second one that addresses a different failure, then confirm both are documented for the exact model.
Check the Door Before Choosing a Lock Style
Start by identifying whether you need a deadbolt replacement or a set that also replaces the handle. Those are not interchangeable shopping choices: handle sets can change the installation work and may not suit a door with separate hardware. Measure the existing door thickness and deadbolt spacing, and review the lock’s compatibility requirements before ordering. A lock with more backup methods is not a useful upgrade if its hardware does not fit. If you rent or share a home, check permission and keep the original hardware where a reversible installation matters.
Treat Wi-Fi as a Convenience, Not a Backup Plan
Remote app access and voice control can be useful when the household needs to manage entry from elsewhere, but they add dependence on the home network and account access. A local keypad, fingerprint reader, or physical key can be more helpful at the door when internet service is down. Before paying for connected features, decide whether you need remote user management or mainly want reliable everyday entry. Check whether the lock needs a separate hub or has built-in Wi-Fi, as that affects setup and network requirements. Keep at least one entry method that does not rely on your phone or internet connection.
Plan for Battery Changes Before the Warning Appears
Battery backup only helps if someone can replace the batteries before the lock stops responding. Check the required battery type, how the lock signals low power, and whether the warning is visible at the keypad or only in an app. A busy household may benefit from a recurring battery check rather than waiting for a notification that could go unseen. Keep spare batteries in an accessible place, but not somewhere that requires the locked door to reach them. Confirm the manufacturer’s guidance on battery replacement and avoid mixing old and new cells.
Choose Access Methods for the People Who Will Use the Door
Fingerprint entry can reduce code sharing, while a keypad may be easier for visitors or household members who do not want to enroll a biometric credential. Physical keys remain familiar but can be misplaced, and app access can be awkward for someone without a smartphone. Think about children, guests, older relatives, and anyone who may need entry during a phone or network outage. A lock with several methods can simplify these situations, but extra features are useful only if each person can use them confidently. Set up and test the fallback before relying on the lock for everyday access.
Compare Like With Like, Including Finish Variants
Several listings in this group describe the same TEEHO TE001 in different finishes, so a color choice should not be mistaken for a distinct backup system. The two Philips lock-and-handle listings also need to be compared with each other separately from deadbolt-only models. Build a short checklist of the exact model name, included hardware, backup access, connectivity, and door compatibility. Read the model-specific instructions rather than assuming features carry across a brand’s product family. This keeps a familiar brand name or similar product photo from obscuring a meaningful difference.
Frequently Asked Questions
Will a smart lock still work if my home Wi-Fi goes down?
That depends on the lock and the access method you plan to use. A Wi-Fi outage can interrupt remote app control, but a local keypad, fingerprint reader, or physical key may still work if the lock has power and supports that method. Do not treat remote access as the same thing as backup power. Before buying, check the manual for offline behavior and test local entry during setup. If you need access without internet, prioritize a method operated directly at the door.
Does a physical key protect me if the smart lock’s batteries run out?
A physical key can provide an entry route if the electronic controls stop working, provided the specific model includes a key cylinder and the key is available outside the locked home. It does not recharge the lock or restore app features. Keep a spare with a trusted person or in another secure location rather than inside the house. Also check whether the selected version actually includes a keyed override; similar-looking models can differ. For added resilience, confirm whether the lock supports a separate emergency power method.
Should I choose fingerprint entry or a keypad as my main backup?
A keypad is useful when different people need access without sharing a phone or enrolling a fingerprint, while fingerprint entry can make routine access quick for registered users. Neither method is a complete battery-failure solution because both depend on the lock having power. Fingerprints may also be inconvenient for guests or household members who prefer not to enroll. A keypad code can be forgotten or shared too widely. For a household with varied needs, choose the method people will actually use and pair it with a separate fallback.
Can I replace my deadbolt with a lock that also has a handle?
Sometimes, but a lock-and-handle set is a different installation choice from a deadbolt-only replacement. It may be designed for a door with matching handle placement and hardware, rather than simply replacing the existing deadbolt. Check the product’s measurements and installation requirements against your door before ordering. If the current handle works and you want to avoid changing it, a deadbolt-only option may be the simpler fit. When measurements or door preparation are unclear, confirm compatibility with the manufacturer or an installer.
How should I prepare for a smart lock battery dying while I am away?
First, check how the model reports low battery and whether alerts reach you through the app, at the keypad, or both. Set a recurring check or replacement schedule instead of relying on one notification. Make sure another household member knows the physical-key or emergency-power procedure, if the lock supports one. Store spare batteries where they remain accessible without needing to enter through the locked door. Before a trip, test the backup method and confirm that any trusted person who may help can use it.
Conclusion
For the best overall balance, choose the Wyze Auto-Lock Bolt v2 if you want fingerprint and Wi-Fi access alongside backup keys. For value and straightforward keypad use, the TEEHO TE001 is the simpler fit; pick its finish based on your door hardware, not as a feature upgrade. For beginners, the Tapo DL100 is worth a closer look if tactile keypad entry suits your household better than fingerprint or app-heavy access. For a premium connected setup, compare the Yale WiFi Smart Lock and Philips WiFi keypad models against your need for remote control and your door’s hardware layout. For fingerprint-focused entry, consider the eufy C220 or Tapo DL110, then verify the exact backup provisions before choosing. My final advice: match the lock to your door first, then choose the backup method you can reliably use when the battery, phone, or network lets you down.
