BDI Smart Glass Door Lock Keyless Entry with Fingerprint PIN IC Card and App Control

Product Description

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.
