Introducing the unlocking method of the 820 password lock
This lock has two unlocking methods, one is to unlock it with a mechanical key, and the other is to unlock it with a password wheel. The default password of this lock is "0000".
Change password
1. Push the lever on the back of the handle from A to B
2. Then change the password you need
3. The lever on the back handle returns from B to A, and the password has been changed.
Tip: The mechanical key unlocks the lock, and the digital password is invalid regardless of whether it is correct or not. The priority of the mechanical key is higher than the password
