ZKTeco AL40B Fingerprint and Keypad Smart Deadbolt with Bluetooth

The ZKTeco AL40B is a smart deadbolt for front doors and apartments. It adds fingerprint, keypad, card, and phone access to a door that uses an American-style deadbolt. It holds 100 users.

The semiconductor fingerprint sensor reads dry and rough fingers quickly. That matters on a busy door and in harmattan season. A random-password feature hides your code from anyone watching. The Mifare reader accepts cards and tags. Over Bluetooth 4.0 you can unlock and manage the lock with the ZK SmartKey app. A lock-out mode can block all normal users so that only admins can enter, for example while the house is empty.

Voice guidance is available in English, Spanish, or Portuguese, with high, low, or silent volume. The body is zinc alloy. It runs on four AA batteries, not included, rated for about 5,300 openings. It fits doors 35–53mm thick and works from -20 to 55°C.
