Aqara Smart Lock U100.
Aqara Smart Lock U100 — cheaper Aqara sibling: fingerprint + keypad + 8 unlock methods, AAA-powered. Home Key + Matter REQUIRE the Aqara Hub M2 or M3 (unlike the U200 which has the radio built in).
The Verdict.
Gavler Meta-Score
“The hub-paired Home Key value pick. The right Aqara household pick when an Aqara Hub M2 or M3 is already on the network; otherwise the U200 is the better all-in-one $230 value.”
The Gavler Verdict
Precision Engineering
8 Unlock Methods
Apple Home Key (via Aqara Hub), fingerprint, keypad PIN, Bluetooth, physical key, app, one-time guest code, remote unlock. The broadest unlock-method matrix on this list.
AAA-Powered (Long-Life Batteries)
Standard AAA batteries (vs USB-C rechargeable on the U200) — long-life-but-disposable trade-off. Convenient if buyer prefers battery swaps to USB-C charging.
Home Key + Matter Via Aqara Hub
Important: Home Key + Matter compatibility require the Aqara Hub M2 ($60) or M3 ($80). The U100 ships without the NFC secure-element + Thread radio that the U200 has built in.

The Scoreboard
Aqara's value-tier sibling to the U200. Expert consensus reflects the 8-unlock-methods + $40 savings vs the U200; community scores reflect the hub dependency (U200 has Home Key + Matter built in; U100 requires the Aqara Hub M2 / M3 to bridge to either).

Global Critique
“Aqara's U100 is the right value pick for Aqara households that already own an Aqara Hub M2 or M3 on the network.”
“8 unlock methods is the broadest matrix at this price tier — buyers who experiment with entry methods get the most options.”
“If you don't already own an Aqara Hub, the U200 at $40 more is the better all-in-one Home Key pick — the U100 + Hub crosses the U200's price.”
