Half-second entry.
Bluetooth control via the Tuya Smart app — requires the Blusafe Tuya Wi-Fi Bridge for remote access.
The Synthara is a keyless smart door lock with a 3D semiconductor fingerprint sensor that reads in half a second. Unlock by fingerprint, digital code, IC card, the Tuya Smart app, or the included mechanical keys — and hand out temporary codes whenever you need to.
Anti-peeping code entry lets you pad your PIN with random digits so nobody can shoulder-surf it, and passage mode keeps the door free-moving during busy periods. For remote management, add the Blusafe Tuya Wi-Fi Bridge.

Frequently asked questions
Do I need a bridge?
Only for remote access. Within Bluetooth range the Tuya Smart app manages everything. Add the Blusafe Tuya Wi-Fi Bridge to control the lock from anywhere.
What is anti-peeping entry?
You can type random digits before or after your real code — as long as the correct sequence appears somewhere, the door opens. Anyone watching learns nothing.
What if the batteries die?
You'll get low-battery alerts; if they run flat, connect a USB-C power source or use a mechanical key. Batteries are not included — you'll need 4 × AAA.
Is it suitable for rentals?
Yes — temporary codes and revocable cards suit tenants, cleaners and guests, with no key handovers.
