Key ID Registration (Without Scan Tool)

NOTE: The registered key is the key that allows you to start the engine.

If the scan tool is not available, new keys can be registered by operating 2 keys which have been registered to the vehicle.

  1. Turn the ignition switch by using the first registered key, and wait for 5 seconds.
  2. Within 30 seconds, remove the key.
  3. Within 7 seconds after the ignition switch has been turned to the LOCK position, insert the second key and turn on the ignition switch again. Now the theft-alarm indicator light should blink twice for one second. If it does not blink, you have failed to register. Repeat step  1.
  4. Turn on the second key within 30 seconds, remove the key.
  5. Within 7 seconds after the ignition switch has been turned to the LOCK position, turn on the ignition switch by using a new key.
  6. The immobilizer ECU identifies the new key to accept or reject it and operates the theft-alarm indicator.
  7. Repeat steps  2- 6 until a maximum of 8 keys are reached.
  8. If any of the following conditions are satisfied, the additional key registration mode will terminate:
    • The ignition switch has been on for more than 30 seconds.
    • After the ignition key has been turned to the LOCK, the engine control relay is turned off.
    • The scan tool has started communication with vehicle systems.
  9. After the registration mode has terminated, the additionally registered keys should allow you to start the engine.
