Automatic arming
The vehicle is armed immediately after switching the ignition to the 1
(LOCK) position.
The theft indicator will flash every
two seconds to act as a theft
deterrent when the vehicle is
armed.
Automatic disarming
The vehicle is disarmed immediately after the ignition is turned to the 3
(RUN) position.
The theft indicator will illuminate for three seconds and then go out. If
the theft indicator stays on for an extended period of time or flashes
rapidly, have the system serviced by your authorized dealer.
Replacement Integrated Keyless 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 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.
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.

•Press the 7•8 and 9•0
controls on the keyless entry pad
at the same time to lock the
doors (driver’s door must be
closed).
There is a 20 second countdown
when any of the above actions occur
before the vehicle becomes armed.
Each door, the hood, and the trunk
is armed individually, and if any are
open, they must be closed before
the open entry point (door, hood, or
trunk) can enter the 20 second
countdown.
The turn signal lamps will flash once
when all doors, the hood and the trunk are closed indicating the vehicle
is locked and entering the 20 second countdown.
Disarming the system
You can disarm the system by any of the following actions:
•Unlock the doors by using the remote entry transmitter portion of
your Integrated Keyhead Transmitter.
•Unlock the doors by using your keyless entry pad.
•Unlock the driver’s door with a key. Turn the key full rearward
(toward the rear of the vehicle) to ensure the alarm disarms.
•Turn ignition to the 3 (ON) position with a valid SecuriLock™ key or
Integrated Keyhead Transmitter (IKT).
•Press the panic control on the remote entry transmitter portion of
your IKT. This will only shut off the horn and turn lamps when the
alarm is sounding. The alarm system will still be armed.
Pressing the power door UNLOCK control within the 20 second
prearmed mode will return the vehicle to a disarmed state.
Triggering the anti-theft system
The armed system will be triggered if:
•Any door, the hood or the liftgate is opened without using the door
key, keypad or the remote entry transmitter portion of your IKT.
•The ignition is turned to the 3 (ON) position with an invalid
SecuriLock™ key or IKT.
