A Smarter Way to Secure Your Home
The Aqara Smart Lock U300 is designed for simplicity, convenience, and everyday ease. Unlock your door your way with multiple access options, including fingerprint, NFC, passcode, and Apple Home Key.
Installation is quick and hassle-free. If your door uses a standard single-latch (one-hole) design, you can easily replace your existing lock with minimal effort.
With Matter-over-Thread support, the U300 works seamlessly with Apple Home, Google Home, and Amazon Alexa. You can also control and manage it anytime through the Aqara Home app.
Built to last, the U300 runs on 4 AA batteries with up to 10 months of battery life. Its IPX4 rating ensures reliable performance for both indoor and outdoor use.
Note: Some features may require compatible hubs or Matter controllers for full functionality.
