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 SecuriLock
coded 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.

IKTs with remote entry functionality.
