If you live in an apartment or condo complex that doesn’t have a maintenance contract or a resident maintenance person, then a whole new set of rules apply. You have to take full responsibility for replacing a damaged or lost key for the mailbox. You might even choose to replace the mailbox lock if a previous tenant did not return the key, which we’re going to teach you how to do it in a bit. Read on for step-by-step tips on how to replace your mailbox lock, DIY style.

Step-by-Step Mailbox Lock Replacement Guide

DIY mailbox lock replacement guide

Step One

If you had a key, you’d use it to open the mailbox so that you can get to the back of the lock. However, if you’re reading this article, then we’ll just assume that you’ve lost or damaged your key, in which case you’ll have to hold your fire until the mail delivery guy comes to unlock all of the mailboxes. This will be your chance to get access to the rear end of the lock, which is what you need in order to replace your mailbox lock.

Step Two

Once the rear of the lock has been opened, you’ll see that there’s a clip which is holding the lock together. Take it out using an adjustable wrench, and make sure to turn it until it’s standing straight while touching the rear of the mailbox door.

If you look closely, you’ll notice that the clip itself has an extended lip that should be pulled away with pliers until the clip has been completely detached from the lock. At this point, it’ll be easy for you to remove the lock by pulling or pushing it out through the front of the keyhole.

Step Three

Using a screwdriver, remove the locking cam which is situated on the rear of the lock. If you’re wondering what the cam looks like, look out for a dense ‘S’ shaped metal that acts as the lock’s bolting mechanism when you turn the key.

Step Four

Attach the cam onto the back of your new lock, making sure that the cam’s ‘S’ curve is facing the upper part of the lock to make it easier for the key to turn left or right.

Step Five

Now it’s time to attach your new lock to the mailbox keyhole. Start by looping the nut on top of the lock frame and then use your adjustable wrench to squeeze it firmly in place.

Step Six

Grease the entire locking apparatus with a spray and test the lock by turning the key inside it to make sure that it’s working properly.
