It depends on what type of mailbox you have.
Personal Mailbox at Your House
Yes, this one is yours, and a locksmith can open it, rekey it, or replace the entire lock in minutes, no USPS involvement needed.
Cluster Boxes (Apartments, Condos, Gated Communities)
These are USPS property. Only the postal service or a USPS-authorized locksmith can legally open or rekey them. If yours is stuck or the key is lost, start with your property manager or local post office.
Broken Key in a Mailbox Lock
