Without HDS

  1. Start the engine.
    • If the engine does not start, go to the immobilizer system troubleshooting (see SYMPTOM TROUBLESHOOTING INDEX ).
    • If the engine starts, go to step 2.
  2. Press the transmitter lock or unlock button at least 10 times to reset the transmitter.
    • If the locks work, the transmitter is OK.
    • If the locks do not work, go to step 3.
  3. Open the transmitter, and check for water damage.
    • If you find any water damage, replace the transmitter and register the new transmitter (see IMMOBILIZER KEY REGISTRATION ).
    • If there is no water damage, go to step 4.

  5. Reprogram and register the transmitter (see IMMOBILIZER KEY REGISTRATION ), then try to lock and unlock the doors.
    • If the doors lock and unlock, the transmitter is OK.
    • If the doors do not lock and unlock, substitute a known-good transmitter, register it and recheck (see IMMOBILIZER KEY REGISTRATION ). If still not operating, replace the immobilizer-keyless control unit (see IMMOBILIZER-KEYLESS CONTROL UNIT REGISTRATION ).
      NOTE: As the keyless transmitter is combined with the immobilizer transponder, so when the transponder is registered by the HDS, the keyless transmitter is also registered automatically.
