Ultraloq U-Bolt (Z-Wave)

Quick verdict

A Z-Wave lock built for the US market with fingerprint, keypad, and mechanical key backup. Z-Wave means it is fully local with Home Assistant via Z-Wave JS, with no cloud involved at all. The built-in fingerprint reader is a nice touch that many Z-Wave locks lack. If you are committed to Z-Wave, this is a strong option. If you are building a new setup, consider whether Matter locks might be a better long-term bet.

Standout: Z-Wave smart lock with built-in fingerprint reader and keypad. Fully local, zero cloud.
