What This Service Costs
Mailbox lock replacement is generally a quick job, and cost depends on the lock size and mailbox brand. The tech confirms the price before installing anything.
If your mailbox is part of a USPS cluster box unit, that lock is maintained by the postal service and outside what we're able to replace, we'll point you in the right direction if that's the case.
Individual Boxes vs. Cluster Box Units
If your mailbox stands alone at your property, on a post at the curb or mounted by your door, we can replace its lock like any other residential lock. These are the boxes we work on every week around Evansville and the surrounding towns.
USPS cluster box units, the shared bank of mailboxes common in newer subdivisions, are federal property and serviced only by the postal service. If you're dealing with a locked-out CBU compartment, that call needs to go to USPS rather than to us.

Mailbox locks seem small, but a lock you can't open means mail piling up or sitting exposed. We treat these calls with the same urgency as a door lockout.
We're upfront about what we can and can't touch, which is why we tell every caller with a shared cluster box that it's a USPS matter, instead of taking the job anyway.
Post mounted mailboxes around Evansville see a lot of wear from weather and from being brushed by mowers and snow plows over the years, which loosens the housing even when the lock itself is fine. We check the mounting along with the lock so the replacement actually holds once we're gone.
