Infiniti Vehicle Immobilizer System The Infiniti Vehicle Immobilizer System is a sophisticated theft deterrent system that immobilizes the G20 if someone tries to start the vehicle without the authorized Infiniti ignition key. Separate from the G20's standard vehicle security system, the Immobilzer uses a computer microchip transponder mounted in the key, which sends its ID code to the unit's engine control unit (ECU). Once the proper code is verified, the ECU sends another code to the car's engine control module (ECM).
