Replacement of integrated keyhead transmitters (IKT) and coded
keys
Note:Your vehicle comes equipped with two integrated keyhead
transmitters (IKTs). The IKT functions as both a programmed ignition
key that operates all the locks and starts the vehicle, as well as a remote
keyless entry transmitter. A maximum of eight coded keys can be
programmed to your vehicle; only four of these eight keys can be IKTs
with remote entry functionality.
If your IKTs or standard SecuriLockcoded keys are lost or stolen and
you don’t have an extra coded key, you will need to have your vehicle
towed to an authorized dealer. The key codes need to be erased from
your vehicle and new coded keys will need to be programmed.
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
SecuriLockcoded keys to your vehicle. This procedure will program
both the engine immobilizer key code 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
SecuriLockkeys.
•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.
