Last Updated: April 2026
A smart lock is one of the most practical home security upgrades you can make. It eliminates the risk of lost keys, lets you grant temporary access to guests or cleaners, and integrates with your security system for automated locking when you arm your alarm.
But not all smart locks work the same way — and compatibility with your security ecosystem matters more than most buyers realize. We compared the top smart locks for 2026 across connectivity, smart home support, security features, and value.
Quick Comparison: Best Smart Locks 2026
| Smart Lock | Price | Connectivity | HomeKit | Z-Wave | Auto-Lock | Best For |
|---|---|---|---|---|---|---|
| Schlage Encode Plus | $330 | WiFi + HomeKit | Yes (Apple Home Key) | No | Yes | Apple households |
| Yale Assure Lock 2 | $250–$300 | WiFi / Z-Wave / Zigbee / Matter | Via module | Yes | Yes | Security system integration |
| August WiFi Smart Lock | $230 | WiFi + BLE | Yes | No | Yes | Renters (retrofit) |
| Level Lock+ | $329 | BLE + Matter | Yes (Home Key) | No | Yes | Invisible smart lock |
| Schlage Encode | $300 | WiFi | No | No | Yes | Budget WiFi option |
| Kwikset Halo | $200 | WiFi | No | No | Yes | Budget WiFi deadbolt |
What Makes a Good Smart Lock for Home Security?
Unlike a regular deadbolt, a smart lock needs to work reliably with your other security devices. Here’s what matters most:
- Protocol compatibility: Z-Wave and Zigbee locks integrate directly with security hubs like Abode. WiFi-only locks work independently but can’t trigger alarm automations.
- Auto-lock: Automatically relocks after a set time — critical because people forget to lock doors 20% of the time.
- Tamper alerts: Good smart locks detect forced entry attempts and send notifications.
- Battery life: Most run 6–12 months on standard batteries. Check if you get low-battery warnings.
- ANSI/BHMA grade: Grade 1 is commercial-strength. Grade 2 is residential standard. Avoid Grade 3.
1. Schlage Encode Plus — Best for Apple Households ($330)
The Schlage Encode Plus is the gold standard for Apple HomeKit users. It’s one of only two locks supporting Apple Home Key, letting you unlock with a tap of your iPhone or Apple Watch — no app needed, works even when your phone is dead.
Pros
- Apple Home Key support (tap to unlock)
- ANSI/BHMA Grade 1 (commercial-grade security)
- Built-in WiFi — no hub required
- Works with Alexa, Google Home, and HomeKit natively
- Snap ‘n Stay technology for easy installation
Cons
- $330 is premium pricing
- No Z-Wave — won’t integrate directly with most alarm panels
- Bulky compared to Level Lock
Best for: Apple ecosystem users who want the fastest, most seamless unlock experience. Pairs perfectly with a HomeKit security system like Abode for complete Apple Home integration.
2. Yale Assure Lock 2 — Best for Security System Integration ($250–$300)
The Yale Assure Lock 2 is the most versatile smart lock available. With swappable modules for WiFi, Z-Wave, Zigbee, and now Matter, it works with virtually every smart home and security ecosystem.
Pros
- Modular design — swap connectivity modules as needed
- Z-Wave module integrates directly with Abode, SmartThings, and other security hubs
- ANSI/BHMA Grade 2 residential security
- Touchscreen and key-free options available
- Works with all major voice assistants
Cons
- Modules sold separately ($25–$50 each)
- No Apple Home Key support
- DoorSense sensor can be finicky
Best for: Users who want their smart lock to integrate with a Z-Wave security system like Abode Smart Security Kit. The Z-Wave module enables automations like auto-locking when you arm your system.
3. August WiFi Smart Lock — Best for Renters ($230)
August’s retrofit design attaches to your existing deadbolt — you keep your original key and exterior hardware. This makes it the top choice for renters who can’t replace their landlord’s lock.
Pros
- Retrofit install — keeps existing deadbolt and keys
- Built-in WiFi, no hub needed
- HomeKit, Alexa, and Google Home compatible
- Auto-lock and auto-unlock (geofencing)
- Compact, modern design
Cons
- No Z-Wave/Zigbee — limited security system integration
- Battery life shorter than competitors (3–6 months)
- DoorSense sensor included but not always reliable
Best for: Renters and apartment dwellers who need a reversible smart lock solution. Pairs well with a no-drill apartment security system like Abode.
4. Level Lock+ — Best Invisible Smart Lock ($329)
Level Lock+ looks like a regular deadbolt from the outside. All the smart technology is hidden inside the lock body — no external keypads, no bulky mechanisms. It’s the only smart lock that’s truly invisible.
Pros
- Invisible design — looks like a normal lock
- Apple Home Key support (tap to unlock)
- Matter support for broad compatibility
- Compact CR2 battery lasts 6+ months
- Physical key backup
Cons
- No keypad option
- No WiFi — needs Bluetooth range or Matter hub
- No Z-Wave integration with alarm systems
- Expensive at $329
Best for: Design-conscious homeowners who don’t want a visible smart lock. Great for front doors where aesthetics matter.
How Smart Locks Work With Home Security Systems
The real value of a smart lock shows up when it’s connected to your security system:
- Auto-lock on arm: When you arm your system (or leave home), the door automatically locks
- Unlock on disarm: Disarming your alarm can auto-unlock the front door for trusted arrivals
- Activity logging: See who locked/unlocked and when — all in one security app
- Forced entry alerts: If someone tampers with the lock, your alarm system triggers
These integrations require a security hub with Z-Wave or Zigbee support. Abode’s Smart Security Hub supports Z-Wave locks (like Yale Assure Lock 2) out of the box, plus CUE automations that trigger lock/unlock based on system state.
Bottom Line: Which Smart Lock Should You Buy?
| If You Want… | Get This | Why |
|---|---|---|
| Best Apple Home Key experience | Schlage Encode Plus | Grade 1 + Home Key + WiFi |
| Best security system integration | Yale Assure Lock 2 (Z-Wave) | Z-Wave module works with Abode, SmartThings |
| Best for renters | August WiFi Smart Lock | Retrofit, no drilling, keeps landlord’s key |
| Best looking (invisible) | Level Lock+ | No visible smart tech |
| Best budget option | Kwikset Halo | WiFi deadbolt at $200 |
For the best overall experience, pair your smart lock with a complete DIY security system that supports Z-Wave. This gives you automated locking, centralized alerts, and one app for everything — no monthly fees required.
Frequently Asked Questions
Which smart lock works with Abode?
Abode supports Z-Wave smart locks including the Schlage Encode Plus, Schlage Connect, Yale Assure Lock 2, and Kwikset SmartCode series. These integrate directly with the alarm — auto-lock when you arm, auto-unlock when you disarm. The Schlage Encode Plus also supports Apple Home Key for tap-to-unlock with your iPhone or Apple Watch.
Do smart locks work with SimpliSafe?
SimpliSafe has its own branded smart lock ($99) that integrates with the system. But it doesn’t support Z-Wave or third-party locks. If you already own a Schlage or Yale, it won’t connect to SimpliSafe.
Can I use a smart lock without a security system?
Yes. Every lock reviewed here works standalone with its own app, plus voice assistants (Alexa, Google, Siri depending on the model). Pairing with a security system adds automation — auto-lock on arm, alerts if the door is left unlocked — but it’s not required.
Which smart lock has the best Apple HomeKit support?
The Schlage Encode Plus is the only major smart lock with Apple Home Key (tap iPhone/Apple Watch to unlock). The Yale Assure Lock 2 and August Wi-Fi Smart Lock also support HomeKit. Level Lock+ supports HomeKit via Thread. All four pair well with Abode for a full HomeKit security setup.
Are smart locks safe from hacking?
Modern smart locks use AES-128 or AES-256 encryption. The biggest risk isn’t hacking — it’s weak user passwords and shared codes that aren’t rotated. Use unique codes, enable auto-lock, and pair with a security system that alerts you when the lock is tampered with.
