Yale Assure Lock 2 Review (2026)
The smallest, sleekest smart lock on the market.
Smart locks used to be bulky and ugly. The Yale Assure Lock 2 changed that. It is significantly smaller than its competitors and comes in a variety of finishes to match your door. It’s the "Best Design" winner in our roundup of Top Subscription-Free Smart Locks.
✅ The Pros
- Design: 30% smaller than the original Assure lock.
- Modular: You can swap the internal module (Wi-Fi, Z-Wave, Matter).
- DoorSense: Alerts you if the door is left ajar.
- Key-Free Option: Available without a keyhole for a minimal look.
❌ The Cons
- Battery Life: The Wi-Fi module drains batteries quickly (3-4 months).
- No Fingerprint: Relies on codes, app, or auto-unlock.
🤔 Verdict: Buy or Skip?
BUY IT IF: You care about aesthetics. It looks amazing on modern doors. The modularity also makes it future-proof.
SKIP IT IF: You hate changing batteries. The Wi-Fi version is power-hungry compared to Aqara or SwitchBot.
❔ Frequently Asked Questions
Can I upgrade it to Matter later?
Yes! That's the best part. You can buy the "Matter Smart Module" separately and plug it into the back of the lock.
Does Auto-Unlock work reliably?
Generally, yes. It uses a combination of GPS and Bluetooth to detect when you arrive home and unlocks the door as you approach.
