Immobilizer System

NOTE: Not all models are equipped with immobilizer system. Models equipped with immobilizer system can be identified by ignition key having a solid urethane head.
NOTE: A valid key must be available when replacing PCM or immobilizer unit, or both components must be replaced. When replacing an immobilizer system component, all working keys need to be reprogrammed into system. Replacing PCM or immobilizer unit will erase previously programmed keys.
