Abstract: The disclosure generally relates to a system and method for randomly generating unlock codes and identifiers for locks, and creating unlock code and identifier pairs. In an exemplary embodiment, the invention is integrated with, or part of, a distributed management system that controls access to various locations, such as, for example, self-storage units, hotel rooms, apartment buildings, storage containers, short-term housing rentals, lockers, equipment rooms, vaults, hospitals, airports, government facilities, nuclear power facilities, water treatment facilities, weapon storage facilities, aircraft cockpits, and any other setting that requires restricted, selective, or monitored access that can be remotely controlled, whereby users can receive unlock codes electronically on their mobile device.

Abstract: The disclosure generally relates to a system and method for managing distributed encrypted combination over-locks from a remote location, where unlock codes for over-locks are transmitted via electronic messaging. In an exemplary embodiment, the invention is a distributed management system that controls access to various locations, such as, for example, self-storage units, hotel rooms, apartment buildings, storage containers, short-term housing rentals, lockers, equipment rooms, vaults, hospitals, airports, government facilities, nuclear power facilities, water treatment facilities, weapon storage facilities, aircraft cockpits, and any other setting that requires restricted, selective, or monitored access that can be remotely controlled, whereby users can request an unlock code via text messaging using a mobile device.
