Abstract: 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.

Abstract: Disclosed is a rotary lock cylinder including a blocking element that engages into the rotor in a closed position while releasing the rotor in an open position. An actuator can be controlled in accordance with data located on the key. In order to displace the blocking element from the closed position into the open position, a latch element is provided which can be moved along with the key. The blocking element can be attached by means of the actuator. The energy required for moving the blocking element is supplied by the user when introducing the key into the key duct such that the load on the power source used for actuating the actuator is minimal.

Abstract: Disclosed is a rotary lock cylinder comprising a blocking element (25, 64) that engages into the rotor (10) in a closed position while releasing the rotor (10) in an open position. An actuator (17, 78) can be controlled in accordance with data located on the key (2). In order to displace the blocking element (25, 64) from the closed position into the open position, a latch element (33, 63) is provided which can be moved along with the key (2). The blocking element (25, 64) can be attached by means of the actuator (17). The energy required for moving the blocking element (25) is supplied by the user when introducing the key (2) into the key duct (11) such that the load on the power source used for actuating the actuator (17, 78) is minimal.
