Abstract: A method for controlling access to a storage unit owned by an owner, wherein a renter can obtain and maintain rights to said storage unit by paying a first rental fee and subsequent periodic rental fee payments according to a schedule. In this method, the storage unit is secured by a lock that is, at least in part, controlled by the renter. A remotely controllable lockout assembly, however, is capable of over locking the storage unit so that the renter can no longer gain entry when the lockout assembly is activated. The method includes remotely controlling the lockout assembly to deny the renter access to the unit when the when said renter has failed to pay said periodic rental fee on schedule and a grace period has passed since said renter's rights to said storage unit have elapsed.
