Abstract
In an immobilizer and a method for initializing the immobilizer, a multiplicity of control devices, all of which must correctly signal back their identification code word before the vehicle can be started, are integrated in the immobilizer. If a control device is exchanged, the new control device must first be initialized. Key code words of two keys are necessary in order to do this. When both keys are accepted by a testing unit and a release signal is delivered to the testing unit through a diagnostics apparatus, the new code words are stored in the exchanged control device.
