If you do not have a door scope, etc., create a pseudo card as a special unlocking method. This is a dimple-shaped card that uses 85 micron thin aluminum tape and does not have holes. This improves production efficiency, eliminates the aluminum tape dust that was created using the conventional method, and eliminates the cause of operational defects after unlocking and recovery.
