The vehicle is equipped with type II immobilizer system that will disable the vehicle unless the proper ignition key is used. This system consists of a transponder located in the ignition key, an immobilizer receiver unit, an indicator, and the ECM.

The vehicle has two kinds of keys.

• The black master key for:
  • Ignition switch.
  • Door locks.
  • Trunk lock.
  • Center console lock
• The gray valet key for:
  • Ignition switch.
  • Door locks.

When the key is inserted in the ignition switch and turned to the (II) position, the immobilizer receiver unit sends power to the transponder in the ignition key. The transponder then sends a coded signal back through the immobilizer receiver unit to the ECM.

• The immobilizer system can store up to six key codes.
• If it is necessary to rewrite the ECM, the dealer needs the customer's vehicle, all its master keys and valet keys, and the HDS equipped with an immobilizer program card with the latest version of HDS software. Any key that is not learned during rewriting will no longer start the engine, except keys duplicated with the lock Code Key Duplicator.
• It is possible to add ONE new key without reprogramming all of the keys (follow the prompts in the HDS IMMOBI menu).

• If the proper key has been used, the immobilizer indicator will come on for about 2 seconds, then go off. When the ignition switch is turned OFF, the indicator will blink for about 5 seconds to signal that the immobilizer system has been set correctly, then the indicator will go off.
• If the wrong key has been used or the code was not received or recognized by the ECM, the indicator will come on for about 2 seconds, then it will blink until the ignition switch is turned OFF. For accurate immobilizer system diagnosis, get as much information from the customer as possible. A blinking indicator light means the key was not recognized.
  NOTE: Large metal objects, key fobs, other immobilizer keys, and other transponders can interfere with the immobilizer signal. If an intermittent problem is suspected, remove the ignition key from the key ring.
