The electromagnetic locking apparatus functions on a lock cylinder with a rotor, to whose end is fitted in rotation-restrained manner a driver and a stator surrounding the rotor. It is positioned with respect to the lock cylinder and a control part engageable with the apparatus. The apparatus is characterized in that the locking means (20, 28) have an electromagnet part (20) with a two-part tie rod (401/402) with a return spring (45) acting on one tie rod part and a probe (28) connected to the other tie rod part (402).

A metal flat key with depressions arranged in the key shank for receiving radially displaceably tumbler pins located in the lock rotor for use as a mechanical key outside and as a mechanical/electronic key inside a closing means with additional electronic means arranged in the lock cylinder includes a casing (2B, 2A, 20, 21) for receiving an electronic assembly (5) and which is fixed to the key shank (1), the casing simultaneously being used as the key grip (2). The casing (2A, 2B, 20, 12) on the casing side to the key shank (1) has a connecting part (12) for receiving electric contacts (4) between grip (2) and key shank (1).

A locking cylinder has contact means with a contact support, including one or more contact elements. Each contact element partially surrounds the circumference and is fixed and secured against axial displacement, but while allowing partial radial movement. A concentric contact guidance member with contact guides for the contact elements is rotatable with respect to a common centre but is fixed with respect to the contact support in the axial direction. The contact elements can be brought into operative connection with these contact guides.
