Aqara Smart Lock U100, Fingerprint Keyless Entry Door Lock with Apple Home Key, Touchscreen Keypad, Bluetooth Electronic Deadbolt, IP65 Weatherproof, Supports Apple HomeKit, Alexa, Google, IFTTT, Gray

Main Highlights

【Apple Home and Home Key Support】The U100 is a smart door lock that is fully integrated into Apple Home. It can be unlocked with the Apple home keys by simply tapping an iPhone or Apple Watch, even when the iPhone or Apple Watch is out of power. Moreover, you can manage and share door access for your guests in Apple Home.

【Fingerprint and More Ways to Unlock】The Smart Lock U100 offers multiple ways to unlock, including a high-precision fingerprint reader for up to 50 fingerprints, remotely configurable passwords via the Aqara Home app (For short range use, only Bluetooth connection is required; For remote control, an Aqara Zigbee 3.0 hub is required), one-time local passwords for visitors, and a mechanical key for emergency use. *The NFC card is not included and is sold separately.

【Installation Requirements】Backset of 2 3/8-inch or 2 3/4-inch (60 or 70mm); Wooden door with a thickness between 1 3/8-inch to 2 11/64-inch (35-55mm); Diameter of door hole should be 2 1/8-inch (54mm). Note: More details can be found in the installation requirements image and installation video. * Note: Please use the included strike plate kit; If you find that the screw is too tight to turn the door lock knob normally, please loosen the screw properly.

【Automations with Aqara and Third-Party Devices】With an Aqara Zigbee 3.0 hub, the Smart Door Lock U100 is compatible with third-party ecosystems like Google Home, Alexa, IFTTT as well as the Aqara Home app, allowing it to be easily integrated into a wide range of smart home setups and used in smart home automations. For example, when someone presses the Aqara Video Doorbell G4, you will be able to view who is at your door and easily unlock the U100.

【Auto Lock & Do Not Disturb Mode】Thanks to the built-in gyroscope inside the lock, the auto-lock feature locks the door for you after you close it. Alternatively, you can disable this feature and leave the door always open. Also, the Do Not Disturb mode can mute the door lock sounds within a certain period of time, to avoid affecting your family’s sleep when you get back home late.

【Durable and Secure Biometric Door Lock with Long Battery Life & Operating Temperature】U100 is powered by 4 AA 1.5V batteries (included) and has a long battery life of up to 8 months. A USB-C port for emergency charging is available. The lock body made of zinc alloy has an IP65 rating and complies with the same safety standard as BHMA Level 3. It’s capable of withstanding temperatures ranging from -31°F to 151°F. Your sensitive data (e.g. fingerprints) is stored locally and fully AES encrypted.
