The best smart lock for home security is the one that fits the door, gives every person a separate credential, reports useful access events, and still lets the household enter when the phone, internet, hub, or battery fails. The five models below cover different priorities, but the buying decision should start with the door and access plan—not the app.
Best smart locks for home security: quick picks
| Pick | Best fit | Check before buying |
|---|---|---|
| Schlage Encode Plus | Apple households that want keypad, key, and supported wallet access | Door fit, platform support, remote-access setup, finish availability |
| Yale Assure Lock 2 family | Buyers who want several connectivity and keyway choices | Exact model, module, key/no-key design, hub requirements |
| August Wi-Fi Smart Lock | Renters or owners who want to keep the exterior hardware | Existing deadbolt compatibility, interior clearance, battery plan |
| Level Lock+ | Homes that want low-profile hardware and Apple-focused access | Door alignment, key fallback, platform fit, battery access |
| Abode Lock | Abode households that want lock access beside a sensor-led alarm | Exact Abode setup, door fit, user roles, alarm and automation tests |
Prices, bundles, platform support, and included parts change. Confirm the exact model and current product page before ordering.
How we judge a security-focused smart lock
A lock earns a place here only if its design can support a safe access lifecycle: separate users, revocation, a local entry method, useful event history, battery warnings, and a practical fallback. App polish matters less than a free-moving bolt, a strong strike installation, and a household that knows what to do during a failure.
1. Physical fit and free bolt movement
Measure door thickness, backset, bore diameter, latch, handing, trim clearance, and the distance from the deadbolt to any handle. Close the door slowly and turn the existing deadbolt with one finger. If it binds, fix the hinge, weather seal, frame, or strike before adding a motor. A smart motor should not be used to force a misaligned bolt.
2. More than one local entry method
Keypad, physical key, supported fob or wallet credential, and interior thumb turn give a household options. At least one method should work without the primary phone or home internet. Decide whether a keyway is a benefit or an exposure for the property, then manage spare keys like any other credential.
3. Named users and clean removal
Give each resident, cleaner, dog walker, contractor, or caregiver a separate identity. Avoid one shared household code. A good setup lets the owner remove one person without changing access for everyone else. Temporary schedules are useful only after the household tests start time, expiry, time zone, daylight-saving behavior, and offline behavior.
4. Door state beside lock state
“Locked” does not prove the door is closed or that the bolt entered the strike. Pair the lock with a contact sensor when security depends on knowing whether the opening is actually secure. Test open, closed, locked, unlocked, forced-open, held-open, and low-battery conditions.
5. Account and privacy controls
Use named accounts, MFA where offered, minimum permissions, and current recovery details. Decide who can see access history, receive alerts, issue credentials, change automations, and connect third-party services. Entry logs should solve legitimate safety and troubleshooting needs, not become covert household surveillance.
1. Schlage Encode Plus: best for Apple households
Schlage Encode Plus is a strong fit when the household values familiar keypad and key entry alongside supported Apple access. The visible keypad is straightforward for guests and family members who do not want an app. The tradeoff is a larger exterior presence and the need to verify the exact platform and remote-access setup.
Choose it when: you want several entry methods, a recognizable lock format, and an Apple-friendly access path. Skip it when: you need invisible hardware or the door cannot accept its dimensions without conflict.
2. Yale Assure Lock 2 family: best for configuration choice
The Yale Assure Lock 2 line suits buyers who want to choose between keyway styles and connectivity options. That flexibility also creates a buying risk: two locks with similar names may have different modules, platform support, or included parts. Buy by exact model number, not a family name in a search result.
Choose it when: you can match the precise model to the household’s platform and fallback plan. Skip it when: nobody is willing to document the module, hub, and recovery path.
3. August Wi-Fi Smart Lock: best retrofit for renters
August replaces the interior side of many compatible deadbolts while leaving the exterior appearance and keyway in place. That can reduce visible change for a rental and preserve familiar key entry. Compatibility, interior clearance, battery demand, landlord permission, and restoration still need to be checked.
Choose it when: preserving exterior hardware matters and the existing deadbolt is compatible. Skip it when: the bolt binds, interior trim conflicts, or a written lease rule prevents the modification.
4. Level Lock+: best low-profile design
Level Lock+ puts much of the mechanism inside the door, which keeps the exterior understated. It is attractive for Apple-focused households that dislike bulky smart-lock hardware. Installation tolerances matter: an elegant lock is a poor choice if the door or strike makes the bolt work hard.
Choose it when: low-profile appearance and supported Apple entry are priorities. Skip it when: the door alignment is marginal or the household needs a large, obvious keypad.
5. Abode Lock: best alongside an Abode alarm
The Abode Lock is the most relevant choice for a household already comparing the Abode Smart Security Kit and current Abode plans. Its value is not that a lock replaces an alarm. It is that door access can sit beside entry sensors, sirens, user roles, and supported routines in the same security plan.
Choose it when: the home wants lock access and sensor-led security under the Abode setup. Skip it when: the exact door fit, access methods, or required Abode components do not match the property.
Smart lock versus home-security system
| Job | Smart lock | Sensor-led alarm |
|---|---|---|
| Control authorized entry | Primary job | May manage users or routines |
| Know whether door is open | Not guaranteed | Door contact can report state |
| Detect motion or broken glass | No | With the right sensors |
| Sound a whole-home alarm | Usually not the core role | Core role |
| Professional monitoring or dispatch | No | Only under the selected service and event rules |
| Smoke/CO or water safety | No | Only with compatible listed devices and services |
Security setup checklist
- Photograph the existing hardware and measure every required door dimension.
- Correct binding, loose hinges, weak screws, or strike misalignment.
- Confirm landlord, HOA, fire-door, or master-key restrictions.
- Choose the exact lock model, keyway, finish, keypad, hub, and platform.
- Create named administrators and users; enable MFA where supported.
- Give temporary users individual credentials with tested schedules.
- Pair a contact sensor if door state matters.
- Document the local fallback, battery type, recovery owner, and support route.
Failure tests every buyer should run
| Test | Pass condition |
|---|---|
| Internet disconnected | Local entry and exit still work; remote limits are understood; restoration is reported |
| Hub or bridge offline | Local credentials remain safe; the household gets a useful warning |
| Primary phone lost | A second authorized path works; account recovery does not depend on that phone |
| Low or dead battery | Warnings arrive early; replacement and supported emergency entry are proven |
| Removed user | Old code, app share, wallet key, voice link, and alarm role all fail |
| Door pushed or pulled | Bolt still moves freely and the contact sensor reports the right state |
| Power outage | Lock entry works; router, hub, alarm, cameras, and monitoring limits are known |
Automations worth using—and ones to avoid
Good routines turn on an entry light, warn when a door remains open, or prompt the owner to check an unlocked door at night. High-impact actions need more caution. Do not make unlocking or disarming depend on a broad geofence, an unauthenticated voice command, or one phone joining Wi-Fi. Test every routine with guests, pets, shared devices, internet loss, and daylight-saving changes.
Three-year cost worksheet
Add the lock, keypad, bridge or hub, contact sensor, alarm equipment, batteries, subscription, monitoring, locksmith work, replacement parts, spare keys, network backup, lockout risk, and restoration at move-out. A cheaper lock can cost more if it needs frequent batteries, a separate bridge, or service work on a poorly aligned door.

Verdict
Schlage Encode Plus is the best broad pick for an Apple household that wants several familiar entry methods. Yale Assure Lock 2 is the configuration pick, August is the renter-friendly retrofit, Level Lock+ is the low-profile option, and Abode Lock is the natural candidate beside an Abode sensor system. Whichever lock wins, door fit, named access, clean removal, a contact sensor, and tested offline entry do more for security than an impressive feature list.
Frequently asked questions
Can a smart lock make a door physically stronger?
Not by itself. Door, frame, strike, fasteners, hinges, glazing, and installation all affect resistance.
Should a smart lock have a physical key?
It depends on the property’s threat and fallback plan. If there is no keyway, prove another local emergency method.
Does a smart lock work when Wi-Fi is down?
Many locks retain some local methods, but remote access and automations may change. Test the exact model offline.
Can a smart lock replace a security system?
No. Access control is different from intrusion detection, whole-home sirens, monitoring, dispatch, cameras, and life safety.
