CompX National Mailbox Keys

Replacement keys for CompX National mailbox locks. They fit cluster box units, parcel lockers and apartment mailboxes. Every key is cut to code to match your original.

Your key code is stamped on the front of the lock. On some mailboxes it is on the metal tab at the back instead. Mailbox codes often end in letters as well as numbers, so write the whole code down.

CompX National builds the compartment locks used in cluster box units, gang mailboxes, horizontal apartment boxes and parcel lockers. If your CBU key is long gone, the code on the lock is all we need to cut a new one. Where no code is left, replacing the lock is the way back in, and new keys come with it.
