BDI Smart Glass Door Lock Keyless Entry with Fingerprint PIN IC Card and App Control
Upgrade your glass door security with this advanced biometric smart lock, designed for both push-pull and sliding doors. Supporting fingerprint, password, IC card, and Tuya APP (Bluetooth) unlocking, it offers a seamless keyless experience for your home or office.
The lock features a 3mm thick stainless steel double-groove locking tongue, providing exceptional strength and durability. Its innovative left/right interchangeable design allows for tool-free reversal, making installation quick and hassle-free. Even if the circuit fails or the battery dies, the flexible mechanical emergency key directly drives the lock tongue-ensuring you're never locked out.
Equipped with a metal gear stepper motor, this lock prevents motor burnout from stalling. The non-removable rear shell and reserved mounting holes enable fast installation without disassembly. Other smart features include anti-pry alarm, low battery reminder, fake password protection, and time-based always-unlock mode.
With a wide working temperature range (-20°C to 55°C) and ultra-low standby current (<30μA), this lock is reliable in various environments. It supports up to 100 fingerprints, 1,000 passwords/cards, and includes an emergency power port for unexpected battery drainage. Secure, smart, and sturdy-this is the perfect access solution for glass doors.
