1. Insert a previously programmed
coded key into the ignition.
2. Turn the ignition from the 1 (off)
position to the 3 (on) position. Keep
the ignition in the 3 (on) position
for at least one second, but no more
than 10 seconds.
3. Turn the ignition to the 1 (off)
position, and remove the coded key
from the ignition.
4. After three seconds but within ten seconds of removing the previously
programmed coded key, insert the other previously programmed coded
key into the ignition.
5. Turn the ignition from the 1 (off) position to the 3 (on) position. Keep
the ignition in the 3 (on) position for at least one second but not more
than 10 seconds.
6. Turn the ignition to the 1 (off) position, and remove the second key
from the ignition.
7. Within twenty seconds of removing the previously programmed coded
key, insert the unprogrammed key (new/valet key) into the ignition.
8. Turn the ignition from the 1 (off) position to the 3 (on) position. Keep
the ignition in the 3 (on) position for at least one second.
9. Your new unprogrammed key is now programmed.
If the key has been successfully programmed it will start the vehicle’s
engine and the theft indicator light will illuminate for three seconds and
then go out. If the key was not successfully programmed, it will not start
your vehicle’s engine and the theft indicator light will flash on and off
rapidly. If failure repeats, bring your vehicle to your authorized dealer to
have the new key(s) programmed.
To program additional new unprogrammed key(s), repeat this procedure
from Step 1 for each additional key.
