Overview
Ultraloq built Wi-Fi straight into the U-Bolt Pro, so this fingerprint deadbolt connects to home internet without a hub for remote unlocking, access logs and shared eKeys. A door sensor tells it when the door has closed so it can lock itself.
Homeowners and short-term rental hosts get remote control, a large fingerprint capacity and commercial-grade ANSI certification in one lock. It connects only on the lower Wi-Fi band, and it is not recommended for metal doors.
Who it's for
Rentals, family homes and small offices that share access often suit the eKeys, logs and fingerprint capacity. Metal doors are not recommended for this lock.
Pros and cons
- Wi-Fi built in, no hub
- Large fingerprint capacity
- Access logs and eKey sharing
- Auto unlock on approach
- Lower Wi-Fi band only
- Not recommended for metal doors
- Electronics warranty shorter than mechanical
Performance notes
Remote features run through the built-in Wi-Fi, while the door sensor confirms the door is shut so auto-lock can engage. Auto unlock senses your phone as you approach and opens the bolt on arrival.
