Mailbox Lock Replacement
It depends on the mailbox. For many cluster boxes (CBUs) in newer subdivisions, the Postal Service controls the master lock that opens the front panel, but the lock on your individual compartment belongs to you or your HOA. That compartment lock is the one a locksmith can replace when a key is lost or a new owner moves in.
For apartment wall units and privately owned locking mailboxes, we can replace or rekey the lock directly. Apartment residents should check with their property manager first, since some communities handle mailbox locks themselves or require them to match a building system.
Changing the lock after you move in is sensible for the same reason as rekeying your front door: you don’t know how many copies of the old key are out there, and mail theft often starts with a spare key.
How It Works
Quick, affordable, and your mail stays yours.
Wall unit, cluster box or standalone? Home, apartment or HOA?
We open the door, remove the old lock and fit a new cam lock.
You get fresh keys, and the old key — wherever it is — no longer works.
