In the case of distributed systems, some of the components and / or information are located in a control center, from where the connection to the vehicle is established via wireless communication.

This protection against theft can be increased by the control unit 1 and the base part 3 are coordinated so that each Base part 3 can only work with a very specific operator 1 1. This can result from appropriate coding.
