Centralized mailboxes are a safe option for receiving mail and packages, thanks to their locking compartments and powerful construction. Each customer compartment has its own lock, and though these locks are strong and resistant to tampering, there is always the chance a key will break inside a lock, or wear and tear will require replacement. If you are the property manager, you’ll be responsible for this repair.
The good news is that replacing a mailbox lock is an easy process that should only take a few minutes with the right tools.
To Get Started
Before you begin, contact your local post office to let them know you’ll carry out this repair. To access the inner lock, the postal service will need to open the master door for you. Once the master door is open, follow these steps.
- Undo the latch to the master doors to open them. This will expose all the locks.
- Using a nut driver (1/2 inch) undo the nut that is holding on the lock that needs to be replaced.
- Then, open the door and take off the cam, which is the square piece held down by the nut. This will expose the lock and its clip.
- Close the master door and open the customer compartment door to work on the clip. Remove the clip by pulling downward, and this will allow you to take out the old lock. Use channel lock pliers for best results.
Replace the Old Lock with A New One
Now with the old lock removed, it is time to replace the old lock with the new one.
- Remove the key from the new lock and insert it into the opening.
- Using the channel lock pliers, install the new clip by sliding it upward over the lock.
- Once these two parts are installed, place the cam back over the lock, sliding it on via the opening.
- Using the nut driver, replace the nut to secure the cam to the lock.
Close the mailbox door, and the new lock should be ready for use.
