I just received my cluster box unit and I cannot find the tenant keys, mounting hardware or installation instructions…what should I do?

All of the keys, mounting hardware, and installation instructions ship inside the mailbox cabinet. Once you have the mailbox module out of the carton and on a workbench, open up the outgoing mailbox door which will not have a lock on it (directly below the outgoing mail slot on the right-hand side) (the local USPS installs this lock – see above),  and push up on the latch located on the left side of the interior of this compartment. BE CAREFUL. THE UNIT IS FRONT HEAVY. This will release the right side of the cabinet like a French door. Subsequently, the left side of the cabinet can be opened by releasing the latch. All of the keys, mounting hardware and installation instructions will be appropriately marked in the lower left hand compartment.
