Confirm the lock brand because the setting modes vary depending on the brand. The following shows common methods for restoring factory settings:

1. FingerCrystal smart door locks: Open the rear cover, press and hold the SET button, and factory reset based on the voice prompt. To factory reset for a new firmware version, the administrator password is required for verification. Note: If you forget the administrator password, first contact customer service personnel to get the required string of digits. Then remove the battery, press and hold the SET button, and power on the smart door lock. After hearing a prompt tone, enter the string of digits obtained from purchasing channels.
