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. The immobilizer-ECU identifies the new key to
accept or reject it, and operates the immobilizer
indicator (See the table below).
5. 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 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
