Immobilizer Indicator
The immobilizer system turns on the indicator light after the ignition system enters the vehicle ON mode and then starts the authentication process. The indicator light comes off after the control unit confirms the chip code is correct. The indicator light in this step tells an abnormality in the system, or success/failure of the key authentication.
Ignition Key
Vehicles equipped with the immobilizer system have an identification marking on the mechanical key. Consider this identification marking as a proof of the vehicle having the immobilizer system.
