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.

The puck lock security hasp system includes a base, curved upright walls extending from the base, flanges extend outwardly from the curved upright walls, and a U-shaped lock. A standard puck lock can be secured on the base within a space between the curved walls. The U-shaped lock can be positioned and secured over the curved walls to block the keyhole of the puck lock. In some embodiments, the U-shaped lock may include: a hollow pipe filled with a dye or paint for marking a thief cutting into the lock; sections of hollow pipe in the straight parts of the shackle for resisting sawing of the shackle; and/or multiple keyholes, with only one being operable to open the lock.

The invention relates to a disassemblable hinge (1) having a latching member (2), adapted to be associated with an openable door (20), and a hinge member (3), adapted to be associated with a corresponding door frame (21). The latching member (2) comprises a main body (4) and a catch (5), wherein said main body (4) comprises a hinge slot (6) adapted to receive said hinge member (3), wherein said catch (5) is rotatably engageable with said hinge member (3) around a first axis (A1). The catch (5) is movable between a closed state and an open state, and into a disengaged state. The catch (5) and said hinge slot (6) defines a space (14) for housing said hinge member, wherein said catch (5), in its closed state, locks said hinge member (3) in said space (14). The space (14) is expanded when said catch (5) is moved from said closed state to said disengaged state. The catch (5) is moved from said disengaged state to said open state by rotating said catch (5) around a second axis (A2), thereby releasing said hinge member (3) from said space (14). Thereby a disassemblable hinge is provided enabling a secure opening operation in a two step maneuver.

The lock of the present invention includes a housing, a fastening element, a stopping element, a first locking mechanism and a second locking mechanism. The fastening element is movable relative to the housing and is selectively located at a securing position and a releasing position; the stopping element has a first state and a second state. The stopping element in the first state restricts the fastening element to be in the securing position while the stopping element in the second state releases the fastening element. The first locking mechanism includes a dynamic element and a sensing device. The dynamic element drives the stopping element to change between the first state and the second state. The sensing device senses a signal and controls the dynamic element.

A dual hasp conventional trailer door lock has a lever arm that is secured between a fixed lower hasp and a swivel upper hasp so as to align an upper hasp hole with a lower hasp hole. The present invention has an elongate body that rests against the door to cover the two hasps. A lockable pin is manually pushed through the holes from a key end to an anchor end of the lock body. An electronic motion sensor is housed in a hollow in the body. Any tampering of the body triggers any one of an alarm sound and/or phone transmission and/or flashing strobe light.
