Removing a mailbox lock yourself will save you money from having to hire an expensive locksmith to remove it for you. A mailbox lock is usually found near condominiums or an apartment complex. Many mailboxes will be connected together in a large metal box, for easy postal worker access. Mailbox locks are privately owned. The most common reason to remove a mailbox lock is when a new resident moves in and does not have access to the old key. Removal of the lock will only take a few minutes of your time.

If you have lost your mailbox key, show proof of residency to the mail carrier, and she will let you write down the key code for the lock. This can be viewed using a mirror and flashlight pointed at the back of the lock. Give the code to a locksmith to make a new key. This is cheaper than removing and replacing the entire lock.
