Unattended package delivery cross-docking apparatus includes a plurality of storage devices, each having a door with a lock that is locked and unlocked in response to codes. A local lock controller is associated with each of the storage devices and includes an entry device for entering an access code that unlocks the lock when it is locked and a transaction code that locks the lock when it is unlocked. A central operations controller in communication with the local lock controllers is programmed to receive the access and transaction codes entered to each local lock controller, to create an access code for the lock of each storage device upon receiving a transaction code that locks the lock, and to output a notice of the access code to be used to unlock the lock of each storage device when it is locked.
