A method and system for operating an electronic device are provided. The method may include one or more of the following operations. At least one request related to an electronic device may be transmitted. The at least one request includes a controlling request, a communication protocol determining request, or a firmware upgrade request. Operating data generated based on the at least one request may be obtained. The electronic device may be operated based on the operating data.

An electronic door lock includes a dead bolt moved by a deadbolt transmitting assembly, a spring-loaded latch bolt moved by a latchbolt transmitting assembly, a lock core rotated by a core transmitting assembly, and a spring-loaded prying resisting member. A monitoring unit includes sensors respectively corresponsive to those assemblies and the prying resisting member, and a security controller which performs a security procedure in accordance with position of those assemblies and the prying resisting member sensed by the sensors.

A door security apparatus includes a storage container including a slot, a door-locking member and a sensor assembly. The door-locking member is removably disposed within the slot of the storage container. The sensor assembly is associated with the door-locking member. The sensor assembly is configured to detect removal of the door-locking member from the slot of the storage container.

Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

An electronic bolt seal assembly for locking a hasp of a cargo container, the assembly comprising: a bolt member comprising a head and an elongate shank extending therefrom; a locking body with a housing comprising a cavity for engaging the shank of the bolt member such that during use in a locking configuration the locking body is operable to lock the shank to the locking body in response to axial displacement of the shank within the housing; an electronic module arranged at or adjacent the head in a housing, the electronic module having one or more tracking and communication devices and an electronic circuit to communicate the electronic bolt seal assembly's location to a remote communication center wherein the one or more sensors further comprise an accelerometer for sensing movement and orientation of the bolt member.

An integrated lock body system for securing access points. An electronic door lock has a lock body, at least one electrical component within the lock to be monitored, and at least one output for connection to an external unit located remotely from the electronic door lock for monitoring load resistance between the external unit and the electronic door lock. A circuit is mounted adjacent to or within the electronic lock body. The circuit includes an electrical connection to the at least one electrical component within the electronic door lock and an external electrical output for connection to the external unit. The circuit further includes at least one resistor between the electrical connection to the at least one electrical component within the electronic door lock and the external electrical output, the at least one resistor imparting a desired load resistance capable of being monitored by the external unit.

An electronic door lock includes a dead bolt moved by a deadbolt transmitting assembly, a spring-loaded latch bolt moved by a latchbolt transmitting assembly, a lock core rotated by a core transmitting assembly, and a spring-loaded prying resisting member. A monitoring unit includes sensors respectively corresponsive to those assemblies and the prying resisting member, and a security controller which performs a security procedure in accordance with position of those assemblies and the prying resisting member sensed by the sensors.

A padlock is provided with a transceiver to enable authorisation of an unlocking action by an authority. To control power consumption, a motion detector is used to activate the device from a dormant, low power consumption state.

A first portion of a security device, the first portion configured to have a separate state with respect to a second portion and a combined state with respect to the second portion, such that when in the combined state, the first portion is mated, interlocked, and/or locked with the second portion to collectively form the security device.

An alert system configured to monitor a status of one or more supplemental door locks comprises a switch assembly and an alarm. The switch assembly is configured to detect whether one supplemental door lock is unlocked or locked and includes a switch, an indicator, and a communication element. The switch is to be coupled to a locking component of the supplemental door lock. The switch is configured to sense a position of the locking component and generate an electronic signal or data. The indicator is configured to provide a first indication of a status of the supplemental door lock. The communication element is configured to receive the electronic signal or data from the switch and generate a wireless signal that corresponds to the electronic signal or data. The alarm is configured to generate an audible or visible alarm when the switch assembly detects that the supplemental door lock is locked.
