Smart external door lock

[5-in-1 Electronic Lock] The smart lock can be opened by fingerprints, password, app, RFID card, and physical key. You can remotely provide a temporary password to open the lock via the Tuya or Tongtong app, and the app will have open records. [High Recognition Performance] The security lock uses a highly sensitive 3D semiconductor sensor, which can identify fingerprints faster and smarter. At the same time, the electronic lock can store fingerprints of up to 20 people. The material is made of a metal alloy of steel and titanium, resistant to high and low temperatures, falls, and aging. The foldable design helps protect the lock from rain and sun. [Privacy and Security Guarantee] You can set a privacy opening password (random number + correct number + random number). When five incorrect passwords are entered, the smart lock will be locked for 120 seconds. If someone forcibly breaks it, the door lock will emit an audible alarm. [Two Emergency Unlocking Methods] The external smart lock operates on AAA batteries (not included) and circuit connection. If the mounted lock runs out of power, you can use a mechanical key or a USB port as an emergency power source to open the door. [Installation and After-Sales] 12-month quality warranty.
