Product Description

What is a Safe Deposit Lock?

Most modern safe deposit locks are actually two separate locks inside one housing that work together to control a single locking bolt.  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 the guard 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.

Do you need this class? Test yourself with these questions:

  3. Which characteristics are vital when attempting to identify a safe deposit lock?
  4. How can you tell a left-hand lock from a right-hand lock?
  5. Do all safe deposit locks that use two keys have two separate keyways?
