A security device for an item of merchandise is provided. The security device includes a non-programmable locking mechanism comprising a mechanical lock and a programmable locking mechanism comprising a monitoring circuit operatively coupled to an alarm. The security device is configured to secure an item of merchandise from theft or removal when the mechanical lock is locked and to be separated from the item of merchandise when the mechanical lock is unlocked. The alarm is configured to provide an alarm signal if the security device is separated from the item of merchandise while the monitoring circuit is armed.

A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

An electronic lock, such as a deadbolt, with a locking device movable between a locked position and an unlocked position. The lock includes a key fob including a RFID circuit indicative of a valid access code for the locking device. A circuit is provided that is configured to control movement of the locking device between the locked position and the unlocked position. The circuit includes a sensor, such as a contract sensor or a proximity sensor, which detects when a user is within range of a RFID device. When this happens, the sensor is configured to generate an electrical signal, which is used to activate the RFID device for a predetermined period of time. If the RFID device reads a valid access code, the device is unlocked.

Access control electronics tor wireless locks comprise one or more battery operated radios that receive access control codes. The wireless accessed locks locate the electronic components, circuits, sensors and antennas and many of the lock components away from the container being secured and closer to the operator/user. The disclosed access control electronics combine a proximity detection circuit comprising sensor pads and a capacitive sensing circuit and one or more short-range radio frequency antennas for reading RFID devices. The proximity sensor pads are in close proximity with the antennas, without the antennas interfering with the proximity sensing process, and the sensor pads to not attenuate the signals between the RFID devices and the antennas after the RFID devices are detected.

A lock includes a housing assembly, an actuatable lock assembly and a latching assembly. The actuatable lock assembly is positionable in at least a closed orientation and an open orientation. The latching assembly further includes a latch, a cam and a motor. The latch, having a cam profile, is movable between a locked position and an unlocked position. In the locked position, the actuatable lock assembly is maintained in the closed orientation. In the unlocked position, the actuatable lock assembly is positionable into an open orientation. The cam is rotatably mounted and has a first follower configured to intermittently coact with the cam profile of the latch, to, in turn, move the latch between the locked position and the unlocked position. The motor is coupled to the cam. Actuation of the motor causes rotation of the cam, resulting in movement of the latch between the locked and unlocked positions.

A hinged object, such as a door, window, gate, lid, etc., comprises a first hinge, a second hinge, and an electromechanical locking device mounted on or in the hinged object. A first electrical wire is embedded in the hinged object that couples the electromechanical locking device to the first hinge, the first hinge to couple to a low-voltage power source to supply low-voltage electrical current to the electromechanical locking device via the first electrical wire. A second wire is embedded in the hinged object that couples the electromechanical locking device to the second hinge, the second hinge to couple to the low-voltage power supply to return low-voltage electrical current from the electromechanical locking device to the low-voltage power supply via the second electrical wire.

A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.
