Are you the proud new owner of a cluster mailbox unit, but can't seem to find the keys? Don't worry, the keys are actually located inside the mailbox unit itself. To help you locate them, we've put together this guide with a step-by-step video tutorial.

If you've just received your cluster mailbox, you'll find the keys inside the unit itself. Here's how to locate them:

Step 1: Open the Master Door

Start by accessing the outgoing tenant box labelled "US Mail". Open the tenant door by using the small, round opening intended for the USPS Arrow Lock. Then, pull up on the hinge inside the outgoing tenant box you just opened. This will release the master door, allowing you access to all tenant boxes. On double column units, you will open the right column door first followed by the left column door.

Step 2: Retrieve your keys from the Parcel Locker

After you've opened the master door, check the parcel locker for the keys. The keys are usually sealed in a plastic bag and taped to the back of the locker. If the unit you purchased has more than one parcel locker, please check all of them. The keys could also be in one of the smaller tenant boxes, so be sure to check the entire unit if your keys are not located in one of the parcel lockers.

Retrieving Keys from Private Use Units
If you have a private use unit, your Master Lock should arrive installed on the unit. The key to your master lock is usually located in an envelope taped to the side of the unit. Your Master Lock key will be located in the top right corner of the envelope.

If you've lost your keys or they were not included in your shipment, don't worry, you can easily get replacement keys. Contact US Post Company, to get a new set of keys.
