Read on to learn the step-by-step procedure to open a mailbox lock when the key is lost.

Contact the Postal Service

Just to reiterate our previous suggestions, before attempting any lock-opening techniques, it's wise to reach out to your local postal service or the relevant mailbox provider. Inform them about your situation, and inquire if they can provide assistance or authorize you to proceed with unlocking the mailbox. Depending on their policies, they may help you or guide you in the right direction.

Assess the Lock Type

Mailbox locks come in various types, including wafer locks, disc-detainer locks, or pin-tumbler locks. Before adopting any method of lock opening, you have to identify the lock type. If you're unsure, take a clear picture of the lock and consult with a professional locksmith for mailbox key replacement.

Gather the Necessary Tools

To open a mailbox lock, you'll need a set of lock-picking tools. These commonly include a tension wrench and a lock pick. You can purchase a basic lock-picking set online or from a local store. Ensure you have the appropriate tools for the lock type you're dealing with.

Apply Tension

Insert the tension wrench into the bottom part of the keyhole and apply slight tension in the direction the key would turn. Keep the tension consistent throughout the process. This will create a binding force within the lock that you can work with.

Pick the Lock

Insert the lock pick above the tension wrench, into the top part of the keyhole. Start gently manipulating the lock pins or wafers one at a time. Apply upward pressure to each pin or wafer while simultaneously releasing tension with the wrench. As you work through the pins, you should feel some give or movement within the lock.

Continue Manipulating Pins/Wafers

This may take some time, but you have to keep trying. Repeat the picking process, focusing on each pin or wafer individually, until all the pins are set. It may take several attempts and adjustments to get the feel for the lock and successfully open it. Patience and practice are key here.

Rotate the Lock

Once all the pins are set, you should feel the lock cylinder rotate slightly. Maintain tension with the wrench and turn the lock in the appropriate direction to unlock the mailbox.
