Replacement mailbox locks and keys for Ecco and Salsbury mailboxes, plus where to get a lock or key for other brands. Start with the brand of your mailbox: the right lock depends on the maker and model, and most manufacturers need a key number or model to cut a new key.
Mail Boss cuts replacement keys by the key number, which is found only on the key itself; without it, contact Mail Boss customer service. Round keys are no longer made, so those mailboxes need a new lock and key set.
Salsbury Industries
Salsbury sells replacement locks and extra keys for its aluminum, vertical, 4C and cluster mailboxes. Pick the lock for your mailbox type.
Cluster box units (CBU)
The builder or property owner provides lock and key service for cluster box units; the Postal Service furnishes only the master access lock (USPS PO-632, 3-2). Residents should ask their HOA or property manager.
Mailbox lock questions
I lost every key. What now?
Mail Boss cannot cut a key without the key number. A replacement lock comes with new keys: 2 with our Ecco locks, 3 with our Salsbury 4C locks.
