Programming spare keys
You can program your own coded keys to your vehicle. Please read and
understand the entire procedure before you begin.
Tips:
• A maximum of eight keys can be coded to your vehicle.
• Only use Securilock௢ keys.
• You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
• If no previously programmed coded keys are available, you must take
your vehicle to your dealer to have the spare key(s) programmed.
1. Insert a previously programmed
coded key into the ignition.
2. Turn the ignition from the 1
(OFF/LOCK) 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/LOCK) position, and remove
the coded key from the ignition.
4. 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/LOCK) 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/LOCK) 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/LOCK) 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
