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 ( 7 a) 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 ( 8 a, 9 a) 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 ).
