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.
