The invention has set itself the task of the assembled with the reader The lock is so small and easy to design that it hardly exceeds the dimensions of a conventional cylinder lock and is inexpensive.

There is known a _r magnetic lock, which is embodied by a relay. This essentially consists of a permanent magnet or electromagnet, which is "assembled" with pole pieces forming magnetic circles and a relay armature or the like to be actuated by them.

To operate this lock, a 3 key is required, which only has soft magnetic inserts in the appropriate places.

Quite apart from the fact that this approach is not suitable, the castle? " simple and inexpensive to design, security against unauthorized opening of the lock can also not be achieved with it.

In order to avoid an external brain G sharp on the nature of the key information and to ensure that it cannot be read without authorization, a further feature of the invention is proposed that the.
