Power Door Locks/Keyless

  1. If the door lock system works properly, but the vehicle does not start, refer to the immobilizer-keyless control unit symptom troubleshooting information (see SYMPTOM TROUBLESHOOTING INFORMATION ).
    NOTE: All functions work with the key out of the ignition switch. Only the panic function will work with the key in the ignition switch and in the LOCK (0) position. There is no keyless function with the ignition turned ON (II).
