A magnetic lock has a barrel and keyway, the barrel when rotated unlocking the lock. Locking element cavities each contain a moveable locking element such as a ball, movable in response to a magnetic field applied by a magnetic key. A locking bar is movable between a locked position and an unlocked position. The locking bar has coded projections which extend into the respective locking element cavities when the locking bar moves from the locked position to the unlocked position. A code plate is shaped in registration with the coded projections. When the locking bar is in the locked position the code plate and the coded projections form a substantially uninterrupted surface. The locking elements prevent movement of the locking bar from the locked position to the unlocked position except when magnetically moved to a coded position.

The invention relates to a key (1) for an electromechanical locking device (101), having a key bow (2), with the key bow (2) comprising a light device (75), and with the key bow (2) comprising electronics (70) which are designed to actuate the light device (75) to reproduce at least one item of information in a luminous manner.

A method for mutually controlling and unlocking a dual plug in a lock includes: unlocking a code of a first plug first, the first plug restricting unlocking of a second plug, the second plug restricting rotating of the first plug before the code of the first plug is unlocked. after unlocking the code of the first plug, the first plug translating to a second position from a first position using a preset position difference, the first plug being unable to rotate during the translation; after moving the first plug to the second position, the first plug releasing a restriction on the second plug, the second plug still restricting the rotating of the first plug; and unlocking the code of the second plug, the first plug and the second plug being able to rotate synchronously so as to unlock the lock after unlocking the code of the second plug.

A passive radio transmission device is arranged on a front and a back of an electrically conductive carrier plate, wherein the radio transmission device includes, on the front of the carrier plate, a first film having a first antenna and having a microchip coupled to the first antenna and, on the back, a second film having a second antenna, wherein the first film is coupled to the second film via a flexible web, routed around an end face of the carrier plate, that connects the front to the back, so that the second antenna is connected to the first film via at least one connecting line running along the web in order to transmit information from the microchip using both the first antenna and the second antenna, wherein the first film, the second film and the web are combined as one component.

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.

An exemplary system includes a mechanical key and an access control device. The access control device includes a housing defining a keyway that has a fixed position within the housing. The access control device further includes a root depth sensor assembly, an insertion depth sensor assembly, a control assembly in communication with the sensor assemblies, and an electronic lock device. The control assembly is configured to determine the bitting code of the mechanical key based upon information received from the sensor assemblies, to compare the bitting code of the mechanical key to a lock/unlock bitting code; and to transmit a lock/unlock command in response to the bitting code matching the lock/unlock bitting code. The electronic lock device is configured to transition between a locked state and an unlocked state in response to receiving the lock/unlock command and without requiring rotation of the mechanical key.
