REGISTRATION OF ADDITIONAL KEY(S)
WITHOUT USING THE SCAN TOOL

If the 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 vehi-
cle.
NOTE: The registered key is the key that allows you to start the
engine.
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 will

start blinking, and then additional registration mode is
entered.

5. Check the immobilizer indicator starts blinking, 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 a new ignition key is registered further, repeat steps 1 to 7

above.

A maximum of eight ignition keys can be registered to one vehi-
cle (If you attempt to register the ninth key, the immobi-
lizer-ECU rejects the key). If any of the following conditions are
satisfied, the additional key registration mode will terminate:

• The immobilizer indicator starts blinking 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 sys-

tems.

9. After the registration mode has terminated, the additionally

registered key(s) should allow you to start the engine.
