Overview
The Aqara Smart Lock U100 (model SDL-D01) is a fingerprint and Apple Home Key deadbolt that lets an iPhone or Apple Watch unlock the door with a tap, even when that device is out of power, built around a zinc alloy body rated IP65 for weather exposure.
Several of the U100's headline features depend on hardware sold separately: sharing Apple Home Keys needs an Apple Home Hub, and remote passcodes plus Alexa, Google Home, and IFTTT integration all require an Aqara Zigbee 3.0 hub. Used standalone, the lock still works by fingerprint, local one-time codes, and the mechanical key. Fingerprint data is stored and AES encrypted on the lock itself rather than in the cloud.
- Apple Home Key tap unlock, works even with a dead iPhone battery
- Fingerprint reader stores up to 50 prints, AES encrypted locally
- IP65 weatherproof zinc alloy body, BHMA Level 3 equivalent
- USB-C emergency charging plus 4 AA batteries rated up to 8 months
Who it's for
Fits households already on Apple HomeKit or building out an Aqara Zigbee hub setup, where the tap-to-unlock Home Key and cross-device automations pay off. Anyone wanting Alexa or Google voice control out of the box without buying a separate hub should factor that extra purchase in first.
Pros and cons
- Apple Home Key unlocks by tap, even at low iPhone battery
- Fingerprint data stored locally with AES encryption, not in the cloud
- USB-C port for emergency charging if batteries die
- Do-not-disturb mode mutes lock sounds at night
- Alexa, Google Home, and IFTTT integration require a separate Aqara Zigbee 3.0 hub
- Sharing Apple Home Keys requires an Apple Home Hub
- NFC card entry is sold separately, not included
Performance notes
A built-in gyroscope triggers auto-lock once the door swings shut, and a do-not-disturb window can mute the lock's sounds overnight. If the 4 AA batteries run down, a USB-C port on the lock allows emergency charging rather than leaving the door unusable. The fingerprint reader stores up to 50 prints locally with AES encryption.
