Embodiments of the invention are directed to merchandise security devices, systems, and methods for protecting an item of merchandise from theft. For example, a merchandise security device may include a lock configured to be secured to a movable structure and a strike plate configured to be secured to a fixed support structure. The movable structure is configured to move along a path into engagement with the fixed support structure to secure the item of merchandise therein in a locked state and to move out of engagement with the fixed support structure for removal of the item of merchandise in an unlocked state. The lock is configured to engage the strike plate in the locked state and to disengage the strike plate in the unlocked state, and the lock is configured to engage the strike plate along the same path as the movable structure.

An electromechanical locking device for a closure element includes a stator, with a rotor, a locking element and a blocking element, wherein the rotor is mounted in the stator, wherein the locking element is movable between two positions, wherein a starting position and a release position can be assumed by the blocking element. In the starting position, the blocking element prevents a movement of the locking element into the second position and in the release position the blocking element enables a movement of the locking element into the second position. The locking device includes a spring element, wherein the spring element interacts with the blocking element such that when the blocking element moves from the starting position into the release position, the spring element is at least temporarily tensioned in such a way that the spring element pushes the blocking element back in the direction of the starting position.

A key for an electromechanical locking device includes a key bow, and with the key bow includes a housing and an, in particular single, button. The housing includes an actuating section for actuating the button and a support section for supporting the actuating section, with the actuating section and the support section being configured in one piece with one another.

A wirelessly charging electronic lock device includes an electronic key and a electronic lock, a key code and a pre-stored matching code are pre-stored in the electronic key, an electronic lock code is pre-stored in the electronic lock, the electronic key includes a wireless charging device and a first wireless signal device, the wireless charging device charges the electronic device by wireless transmission, the electronic lock includes a wireless charging receiving device, a second wireless signal device, and a processing unit, the processing unit is configured to figure out a current matching code, the current matching code is compared with the pre-stored matching code, which is validated as to whether the electronic key matches with the electronic lock.

A key for an electromechanical locking device, wherein a longitudinal axis, a width axis and a thickness axis are defined perpendicular to each other, with a key bow and with a key shank projecting from the key bow along the longitudinal axis for insertion into the locking device, wherein the key bow includes an electrical energy storage device and/or electronics, wherein the key bow includes a frame in which the energy storage device (85) and/or the electronics is received, wherein the frame is rigidly connected to the key shank, and wherein the frame has at least one grip region which forms a top surface of the key bow for a user to grasp.
