A smart lock paired with your security system does something no camera can: it stops people from getting in. Cameras record break-ins. Locks prevent them. But not every smart lock works with every alarm system, and the wrong protocol means your $300 lock won’t talk to your $200 hub.
We tested 6 smart locks with the major DIY security systems. Here’s which ones work, which ones don’t, and which combination gives you the best security per dollar.
Quick Comparison
| Lock | Price | Protocol | Apple Home Key | Works with Abode | Works with Ring | Works with SimpliSafe |
|---|---|---|---|---|---|---|
| Schlage Encode Plus | $300 | WiFi, HomeKit | ✅ | ✅ (HomeKit) | ❌ | ❌ |
| Yale Assure Lock 2 | $180-250 | Z-Wave/WiFi/Matter | ❌ | ✅ (Z-Wave) | ✅ (Z-Wave) | ❌ |
| August WiFi Smart Lock | $230 | WiFi, BLE | ❌ | ❌ (no direct) | ❌ | ❌ |
| Level Lock+ | $330 | Matter, HomeKit, BLE | ✅ | ✅ (HomeKit/Matter) | ❌ | ❌ |
| Kwikset Halo | $200 | WiFi | ❌ | ❌ | ❌ | ❌ |
| Abode Lock | $180 | Z-Wave | ❌ | ✅ (native) | ❌ | ❌ |
Best Overall: Schlage Encode Plus
The Encode Plus is the only lock with Apple Home Key — tap your iPhone or Apple Watch to unlock. No app needed, no fumbling. It connects via WiFi (no hub required) and works natively with HomeKit, which means it pairs with Abode through Apple’s ecosystem.
Why it’s #1: Home Key is the fastest, most convenient unlock method. Battery lasts 6-8 months. Build quality is commercial-grade (Schlage has been making locks since 1920). Auto-lock and auto-unlock based on phone GPS work reliably.
Downsides: $300 is steep. No Z-Wave, so it won’t pair directly with non-HomeKit alarm hubs. WiFi drains battery faster than Z-Wave alternatives.
Best for Alarm Integration: Yale Assure Lock 2
Yale’s modular design is the reason it wins for alarm system users. Buy the Z-Wave module and it pairs directly with Abode, Ring, or SmartThings. Later, swap to a Matter module without replacing the lock. No other lock offers this flexibility.
Why it’s great: Direct Z-Wave pairing means your alarm system can auto-lock doors when you arm “away mode.” CUE automations on Abode can trigger lock/unlock based on sensor events. The slim design fits standard doors without the chunky look of most smart locks.
Downsides: Each radio module costs $30-50 extra. No Apple Home Key. The touchscreen keypad collects fingerprint smudges.
Best Invisible Option: Level Lock+
Level hides inside your existing deadbolt. From outside, no one knows you have a smart lock — same key, same thumb turn, same appearance. It supports Matter and HomeKit, pairing with Abode through Apple Home.
Why it’s unique: Keeps your existing keys working. No exterior hardware to signal “smart home inside.” Apple Home Key support (with the + model). Compact CR2 battery lasts 6-8 months.
Downsides: $330 for a lock that looks like nothing is a hard sell. No keypad option. No Z-Wave for direct alarm pairing.
Best Value: Abode Lock
If you already have an Abode system, their native Z-Wave lock is the path of least resistance. It pairs directly with the hub, shows lock/unlock status in the app timeline, and works with CUE automations. At $180, it’s the cheapest lock that integrates natively with a security system.
Downsides: Only works with Abode. No HomeKit or Matter. Basic design — functional, not stylish.
Which Security Systems Support Smart Locks?
| System | Z-Wave locks | HomeKit locks | Matter locks | Auto-lock on arm |
|---|---|---|---|---|
| Abode | ✅ | ✅ | ✅ | ✅ (CUE automation) |
| Ring | ✅ (limited models) | ❌ | Partial | ✅ (Alexa routine) |
| SimpliSafe | ❌ | ❌ | ❌ | ✅ (SimpliSafe lock only) |
| Vivint | ✅ | ❌ | Partial | ✅ (Vivint app) |
| ADT | ✅ (Alarm.com) | ❌ | Partial | ✅ (Alarm.com) |
SimpliSafe only works with its own branded lock — a dealbreaker if you want the best hardware. Abode supports the most lock protocols, including HomeKit and Matter, which gives you the widest selection.
Best Lock + Alarm Combos
- Apple household: Schlage Encode Plus + Abode (via HomeKit). Tap to unlock with Home Key, auto-lock when system arms.
- Budget setup: Yale Assure Lock 2 (Z-Wave) + Abode. Direct hub integration, CUE automations, $180 lock + $199 alarm kit.
- Invisible lock: Level Lock+ + Abode (via Matter/HomeKit). No one knows you have a smart lock.
- All-in-one: Abode Lock + Abode system. Cheapest and simplest native pairing.
Bottom Line
The Schlage Encode Plus is the best smart lock you can buy right now — Apple Home Key changes how you interact with your front door. Yale Assure Lock 2 wins for direct alarm integration with its swappable Z-Wave module. And Abode supports more lock protocols than any other DIY security system, making it the best hub to build around regardless of which lock you choose.

2026 smart-lock fit checklist (security-first setup)
- Choose lock ecosystems that support reliable auto-lock rules and verified entry events, not just app unlock convenience.
- Prioritize backup access paths (keypad/PIN/physical key) so lock failures do not become lockout events.
- Compare 36-month ownership: lock hardware, bridge/hub requirements, battery replacement cadence, and app subscription dependencies.

2026 smart-lock security integration checklist
- Start with door security: a smart lock is most useful when paired with entry sensors, alerts, and a clear backup key/code plan.
- Check platform fit: confirm Apple Home, Alexa, Google, Z-Wave, Zigbee, or Matter support before buying the lock and alarm hub separately.
- Plan for guests and cleaners: unique codes, temporary access windows, and lock-history alerts matter more than voice control for most homes.
- Test failure modes: verify battery warnings, manual key access, auto-lock behavior, and what happens during internet outages.
