Everyday locks, such as those found in office mailboxes and cabinets, have a lot of use. The more you use a lock, the more important it is that it is working properly. Changing the locks of a mailbox or cabinet is similar to changing the lock of a door, with some important differences. The biggest difference is usually in the mechanics of the lock. When a door lock normally retracts a bolt to open, the key guide in most mailboxes and cabinets is fixed to a bar that rotates with the turn of the key.

The first step to replace the lock is to open the locked mailbox or cabinet. For a standard office mailbox there may be an additional key that the administrator has in his possession. If the key has been broken in the lock, or is missing, the lock can still be opened.

There will be a bolt in the lock, either turned up or to the side. This pin is removed, most of the time by hand (there may be a nut that needs to be disengaged), and the lock can be removed from the hole. The new lock is then inserted into the hole and a new pin is placed to keep the lock secure. If the bar that is bolted to the lock It is too long to be inserted with the lock, it may have to be unfastened. Once the locking cap is secured to the bar and the pin (or secondary nut) is replaced, the lock is ready for use.
