General description of the immobilizer
The described system is a transponder-based immobilizer for an automotive
vehicle.
The immobilizer system consists of :
- up to 4 ignition keys with transponder integrated in the key head
- the antenna for energizing and communication with the transponder
with its integrated electronic modulator/demodulator driver
- the external status indicator (LED) for displaying the immobilizer status
The purpose of the immobilizer system is to provide an additional anti-theft-
system which is installed in the vehicle. Checking of user authorization is
done by use of an ignition key whose head integrates a crypto-transponder.
In case of a blocked immobilizer system (unauthorized key), the ECM control
unit locks the engine control by cutting off the ignition circuit and the injectors
circuit.
The antenna is a coil allowing to create the electromagnetic field ncessary for
transponder operation. The antenna generates an electromagnetic field using
a frequency of 134.2 kHz. This field induces energy into the transponder by
way of its resonant circuit.
The external status indicator (LED) displays the immobilizer status, and has
an additional deterrence function.
