Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
You can program your own Integrated Keyhead Transmitters or standard
SecuriLock™ coded keys to your vehicle. This procedure will program
both the engine immobilizer keycode and the remote entry transmitter
portion of the IKT to your vehicle.Note: A maximum of eight coded
keys can be programmed to your vehicle; only four of these eight can be
IKTs with remote entry functionality.
Tips:
•Only use Integrated Keyhead Transmitters (IKTs) or standard
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 two previously programmed coded keys are not available, you must
take your vehicle to your authorized dealer to have the spare key(s)
programmed.
Please read and understand the
entire procedure before you begin.

keyfrom the ignition.
