Fingerprint, Home Key, and keypad entry in one weather-sealed deadbolt.

Our verdict

The U100 is the diplomat of this category: fingerprint for the Android carriers, Home Key for the iPhone carriers, codes for the guests, and a key for the traditionalists, all on one BHMA Level 3 deadbolt with real weather sealing. Its one structural catch is the familiar Aqara one: remote and Matter features live behind a hub.

What we like

  • Fingerprint reader stores up to 50 prints for phone-free one-touch entry
  • Apple Home Key tap-to-unlock with iPhone or Apple Watch
  • Touchscreen keypad with one-time and periodic passcodes for guests
  • IP65 weather resistance with BHMA Level 3 rated construction

What to watch out for

  • Remote access and Matter features need an Aqara hub
  • Full deadbolt replacement, so it is not a renter retrofit
  • Battery life of up to 8 months is shorter than keypad-only locks

What owners report: Aqara Smart Lock U100

Synthesized from recurring themes in long-term owner feedback.

Most praised

  • Fingerprint entry plus Home Key on one door means nobody in a mixed phone household is stuck with a single method
  • The weather sealed body holds up on exposed doors where indoor rated locks weather badly
  • One-time passcodes handle deliveries and guests without sharing a permanent code

Common complaints

  • Full remote control waits on adding an Aqara hub to the house
  • Battery changes come more often than on keypad-only locks
  • The touchscreen shows smudges after weeks of code entry and wants regular wiping

Who it is for

Homeowners in mixed-platform households who want every entry method on the front door at once.

Every way in, on one door

The fingerprint reader stores up to 50 prints, so extended family and regular help can be enrolled without rationing slots. Home Key tap-to-unlock serves iPhone and Apple Watch carriers, the touchscreen takes one-time and periodic passcodes, and a physical key still works. Few locks at this tier cover all four methods without an add-on.

Built for exposed doors

An IP65 rating means the exterior half shrugs off driven rain that indoor rated locks dislike, and the zinc alloy body carries a BHMA Level 3 rating. The gyroscope based auto-lock secures the bolt when the door closes, and a Do Not Disturb mode quiets the lock overnight. Four AA batteries run up to 8 months, with USB-C emergency power if they fade at the wrong moment.

The hub question

Out of the box the U100 works over Bluetooth and HomeKit locally. Remote locking, voice assistants, and Matter arrive when an Aqara hub joins the house, which Aqara households will already own and everyone else must budget for. Households wanting hub-free remote access should compare the built-in Wi-Fi locks in this guide instead.

Questions, answered

Does the U100 work without an Aqara hub?

Yes for local control: fingerprint, codes, key, Bluetooth app access, and HomeKit all work. Remote access, Alexa, Google, and Matter features need an Aqara hub on the network.

How many fingerprints can the U100 store?

Up to 50 fingerprints, enough for a full household plus regular help, with each user manageable in the Aqara app.

Can the U100 handle an exposed front door?

Yes. The exterior unit is IP65 rated against rain and dust, which suits doors without a porch roof better than indoor rated locks.
