Bank vault door To change the mechanical code lock, you must know the original code and need a key to change the code.
Before changing the mechanical password lock, use the original password assumption 50-60-70 to open the library door. Then, the original password 50-60-70 is adjusted with the code change mark, and the scale code dial should stop at the last digit 70 of the password.
Insert the code change key into the mechanical password key hole on the back. If the code change key cannot be inserted, it means that the password is not properly aligned. Repeat the above process again.
Turn the key to the right until it stops (approximately 1 / 4 turn), and the key remains in the lock. Select a new set of passwords, such as 20-30-40. Pay attention to the last number of the password, do not select the number of forbidden area
Turn the number mark to the left for the fourth time.
Turn the dial to the right until the number "30" passes the code change mark twice and stops on the code change mark exactly the third time.
Turn the dial to the left until the number "40" passes the code change mark once, and stops on the code change mark exactly the second time.
Turn the code change key to the left to stop, and then take out the code change key.
Remember: after changing the new password (for example: 20-30-40), do not close and lock the vault immediately. You should use the opening mark to repeatedly open the new number according to the new number, and make sure that the password lock can be opened before closing and locking Vault gate
