Notes:

1.Please carefully confirm the size of the door before purchase.
2. Please install it in strict accordance with the instructions. Please make sure that the positive and negative poles of the battery are installed correctly to avoid short-circuit damage to the circuit board.
3. Our lock’s default status is to unlock with any fingerprint! If you find that you could unlock the door with any finger after setting your fingerprints, that means you have not programmed a fingerprint successfully, or contact our service team.
4. After registering your first fingerprint, please use the unregistered fingerprint to check if it can be unlocked or not, if yes, that means you do not register the fingerprint successfully and need to register it again following the user guide.
