  • immobilizers are used, in which a code signal is transmitted from a portable transmitter to an evaluation device in the motor vehicle, which then releases the start-up, in particular the motor of the motor vehicle, if the code signal is correct.
  • the portable transmitter is often built into the handle of the ignition key.
  • one coil each is arranged in the area of the ignition lock and in the ignition key. These coils are used both for the transmission of the code signal and in the opposite direction for the transmission of energy which is required for transmitting the code signal.
