Registration of additional key(s) without using scan tool

If scan tool is not available, new key(s) can be registered by operating 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. Within 30 seconds, remove the key.
3. Within seven seconds after the ignition switch has been turned to the "LOCK" (OFF), insert the second registered key (key B) 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 has failed to register. Repeat from step  1.
4. Turn on the key B. Within 30 seconds, remove the key.
5. Within seven seconds after the ignition switch has been turned to the "LOCK" (OFF) position, turn on the ignition switch by using a new key.
