Registration Of Additional Key(S) Without Using The Scan Tool

If the scan tool is not available, new key(s) can be registered by using two keys which have been registered to the vehicle (A maximum of eight keys can be registered to one vehicle). Follow the procedure below to register new key(s) to the vehicle.

1. Turn "ON" the ignition switch by using the first registered key (key A), and wait for five seconds.
2. Remove the first registered key (key A).
3. Insert the second registered ignition key (key B), and turn it to the ON position.
4. After approximately 10 seconds the immobilizer indicator light should flash, and then additional registration mode is entered.
5. Check the immobilizer indicator light flashes, and then remove the second registered key (key B).
6. Insert the third ignition key, and turn it to the ON position.
7. The immobilizer-ECU identifies the new key to accept or reject it, and operates the immobilizer indicator (See the table below).

8. If more new ignition keys are to be registered, repeat steps  1 to  7 above.

   A maximum of eight ignition keys can be registered to one vehicle (If you attempt to register the ninth key, the immobilizer-ECU rejects the key). 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" (OFF), the engine control relay is turned off.
   • The scan tool has started communicating with vehicle systems.
9. After the registration mode has terminated, the additionally registered key(s) should allow you to start the engine.
