other remote entry systems.
Disarming an untriggered anti-theft system
You can disarm the system by unlocking either front door or
the liftgate with your door key. Turn the key all the way to the
end of travel or the system will not disarm.
You can also disarm the system by unlocking the driver's door
by using the UNLOCK button of the remote entry transmitter or
by using the five-digit unlock code on the keyless entry system
keypad.
If the system is armed and you remain in your vehicle, simply
insert the key into the ignition and turn it to ON. This disarms
the system and allows you to open the door and exit without
triggering the system.
Disarming a triggered system
The alarm can be disarmed by:

using the five-digit unlock code on the keyless entry keypad
