Overview
Swapping out a standard deadbolt with a screwdriver, owners get a lock that opens by fingerprint, code, key fob, phone or key. A TTLock Bluetooth app manages scheduled and temporary codes when the phone is near the door.
Many entry options and a long stored fingerprint list suit busy households and short-term rental guests. Out of the box the app works only at close range, so remote unlocking and voice control wait on a separate gateway.
Who it's for
Families with older members or kids, and hosts who hand out temporary codes, get many ways in and a backup power port. Owners who expect Wi-Fi control from anywhere straight out of the box will need the add-on gateway.
Pros and cons
- Many entry methods including key fob
- Self-learning fingerprint recognition
- USB-C port for dead batteries
- Weather-rated for exterior doors
- Batteries not included
- Gateway needed for remote control
- Bluetooth app works only nearby
Performance notes
Fingerprint reliability improves when the same finger is enrolled from several angles and the sensor stays clean, since the recognition learns over use. Battery life depends on how often the lock runs, and the USB-C port powers it long enough to get in if the cells die.
