How do I open the USPS parcel locker on my cluster mailboxes?
The parcel lockers on cluster mailboxes come with what is called a “captive lock.” A captive lock is designed so that once a tenant inserts the parcel locker key; the tenant cannot remove the key. The key can only be removed by the USPS mail carrier on their next visit. If a tenant has a parcel delivery, the USPS carrier will place the parcel locker key and instructions inside the tenant mailbox. The tenant then uses the parcel locker key to retrieve their parcel and the key remains in the parcel locker lock until the postal carrier retrieves it.
