Smart Locks
3D face, fingerprint, keypad and app-enabled smart deadbolts for homes, rentals and small offices.
Smart locks replace the daily key hunt with face, fingerprint, PIN, card or smartphone entry. Our 3D structured-light models reach <0.01% false acceptance for secure residential use, while TTLock-enabled models let property managers issue and revoke timed access remotely. Every lock keeps a mechanical key override, auto-locks on a timer, and fits standard door preparations — so installers can upgrade almost any door without carpentry.

What happens if the battery dies?
A 9V emergency terminal on the outside plus a mechanical key override guarantee access even after a dead battery.
