Mailbox lock replacement

Mailbox locks are tiny, exposed to the weather, and used hundreds of times a year. Most fail by wearing the key down to where it stops working, getting jammed by debris, or having a key snap off in the cylinder.

What we work on

• Curbside residential mailboxes — locking lid mailboxes, locking insert kits, and security-style boxes.
• Cluster box units (CBUs) — the multi-tenant mailbox banks at the end of streets in many newer Richmond Hill neighborhoods. Note: CBU compartment locks owned by the USPS can only be serviced by the Postal Service. We do not pick or replace USPS-controlled locks. We can help with parcel-locker doors and tenant-owned compartments.
• Apartment / community mailroom locks for owner- or HOA-controlled mailboxes.
• Parcel lockers not under USPS control.
• Locking insert kits for retrofit on standard non-locking mailboxes.

Common situations

• Lost the only mailbox key.
• Key snapped in the lock — see broken key extraction.
• Key turns but the cam doesn't release the door — internal mechanism worn.
• Just bought the house and the mailbox key wasn't included at closing.
• Vandalism or break-in damage to the mailbox door.

What we do

1. Verify the mailbox is yours (address ID).
2. Open the lock — extraction or pick where possible, drill where necessary.
3. Replace the cylinder with a fresh standard or upgraded mailbox lock.
4. Cut at least two new keys on site.

What about USPS cluster boxes?

The compartment locks in USPS-controlled cluster mailboxes (the ones with the eagle logo and Postal Service ownership) are USPS property. By regulation, only the Postal Service can change those locks. If you've lost a cluster mailbox key, your first step is contacting your local post office. We can help with the parcel-locker side, the master access door if you're a property manager with rights to it, or any tenant-owned mailbox setup.
