Aqara U500 Smart Glass Lock

The Aqara Smart Glass Door Lock U500 brings smart access to frameless glass doors with a clamp-on design — no drilling, no damage, just strong, seamless security. It fits both single-swing and double-swing frameless glass doors and installs with only a PH1 screwdriver. Despite the fuss-free fit, it's seriously built: a full metal frame, reinforced dual-hook bolts and a genuine through-lock cylinder stand up to prying and forced entry, while an IP65-rated outer panel shrugs off dust, splashes and heavy rain.

Open the door your way. Add a home key to Apple Wallet and tap to unlock with your iPhone or Apple Watch — it even works when the iPhone is out of battery or offline, and access can be shared remotely through the Apple Home app. The high-resolution 160 × 160 fingerprint sensor reads instantly and stores up to 50 fingerprints, with all access data kept locally and AES-encrypted. You can also enter via the keypad password, an NFC card, the Aqara Home app, or the supplied mechanical keys. Built on Matter over Thread and the new Aliro standard, the U500 works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant.

Power is fuss-free: 4 AA batteries last up to 7 months and are easily replaced, with a low-battery warning and a USB-C emergency charging port for power-bank top-ups. A built-in gyro sensor enables Auto-Lock on Close with no extra contact sensor, while Night Latch and Do Not Disturb modes add control and peace of mind. A dedicated doorbell button saves buying a separate chime, and integration with the Aqara Doorbell Camera Hub G410 lets you see and unlock from Apple Home — plus When-if-then automations to trigger lights and other devices when the door opens. Rated IP65 (outer panel) and IP54 (inner panel).
