KAK Keyless Fingerprint Door Lock Bluetooth Front Door

The KAK Keyless Fingerprint Door Lock with Bluetooth is a smart, secure solution for front doors, bedrooms, offices, and gates. This keyless lock blends advanced fingerprint authentication with multiple unlock methods to keep your home safe and conveniently accessible.

Installation is straightforward — no need to punch a new slot. It fits doors with a thickness of 35-50mm and works with doors that open left or right, making it compatible with most standard doors. The lock features a durable aluminum alloy front panel and zinc alloy rear panel in a sleek black finish.

Unlock with ease: a fingerprint unlocks in under 1 second, and you can also open your door via the Tuya App (Bluetooth), keypad, IC cards, or a physical key. For visitors, generate a time-limited temporary password for safe, convenient access. The built-in self-learning AI improves fingerprint recognition over time, so entry stays fast and reliable as the system learns your unique prints.

Designed for real life, this lock supports up to 50 fingerprints and 50 passwords, giving you flexible options for family, roommates, and guests. It operates in a wide temperature range (-30°C to 70°C / -22°F to 158°F) and carries IP53 waterproof protection to handle daily weather and spills. Battery life is strong, up to about 180 days with 4 AA alkaline batteries (not included), with a low-battery alert sent through the app so you’re never unexpectedly locked out.
