Immobilizer System Description

The vehicle is equipped with an 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 control unit-receiver, an indicator, and the ECM/PCM.

This vehicle has two kind of keys:

  • The black master key for:
    • ignition switch
    • door locks
    • tailgate locks
  • 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 control unit-receiver sends power to the transponder in the ignition key. The transponder then sends a coded signal back through the immobilizer control unit-receiver which then sends a coded signal to the ECM/PCM.

 

  • If the proper key has been used, the immobilizer indicator light will come on for about 2 seconds, then go off.
  • If the wrong key has been used whose code was not received or recognized by the unit, the indicator light will come on for about 2 seconds, then it will blink until the ignition switch is turned OFF.
  • If the ignition switch is turned OFF, the indicator will blink for about 5 seconds to signal that the unit has been set correctly, then the indicator will go off.
  • If the customer has lost his key, and cannot start the engine, contact Honda Customer Relations.
