The whole idea is to have a lock that requires two different keys before it can be unlocked. Traditionally, a single key is used to control one side of all of the safe deposit locks in a bank. This key is maintained by the "vault custodian," and is called the "Guard Key." The guard key is always inserted into the lock plug that is the closest to the hinge on modern locks. once theguard key has been turned and left in the turned position, then the key that the renter of the box controls is inserted into the other plug and turned to unlock the box. Naturally enough, the key that the renter controls is normally referred to as the "Renter's Key." only when both keys are inserted and turned can the box be opened.ProductSafe deposit box lockModel NoM-81KUL listedYesGuardian key1master key per lockRenter key2 pcsColorBrassOpeningRight hand (left hand opening for option)U.
