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 an electronic locking device comprising at least one lock unit and a safety key (1) that is provided with at least one control circuit and a transmit and receive circuit which transmits the data signals to the control circuit of the other respective unit. At least one data carrier module (7) comprising an antenna (7a) is provided. The safety key (1) encompasses a mechanical part (3) that is provided with a head (12) and a shaft (4) comprising control areas (5). The data carrier module (7) is inserted into a recess (13, 14, 15) of the mechanical part (3). The safety key (1) is embodied in such a way that it can be or is fitted with at least one second data carrier module (8, 9) which is provided with an independent antenna (8a, 9a) and a frequency that is different from that of the data carrier module. The second data carrier module (8, 9) is or can be inserted into a pocket of a cap (2) which is placed upon the mechanical part (3).
