The Replacement Lock and Key set should be purchased if your lock needs to be replaced due to accidental or deliberate damage. This high security anti-pick anti-drill lock will fit any Mail Boss mailbox model.

Please indicate your model upon ordering — this will determine whether you need a 7-pin tube lock (older models) or a 12-disc wafer lock. Indicating the model and manufacture year of your mailbox will ensure we send you the appropriate lock and cam for your mailbox model. Includes 1 laser cut flat key or round key and instructions for installation. Additional keys can be purchased.


  • 12-Disc Wafer Lock with hardened steel face or 7-pin tube lock
  • High security – anti-pick, anti-drill
  • Includes 1 laser cut key (wafer lock) or 1 round key (tube lock)
  • Installation instructions included

If your lock is defective please contact us as you may qualify for a free replacement.

NOTE: You must indicate your correct model and manufacturing year through your selection, so that we can ensure you receive the correct replacement lock and matching cam.

If you are locked out of your Mail Boss, you may elect to provide an alternative USPS shipping address that you also have access to (i.e. not your locked mailbox); though you will receive a tracking number and then will have to drill through the lock to replace it and open your box anyways. If you would prefer we FedEx it, contact us at (800) 589-7990 to provide additional payment.
