Locks and Security Each door, the hood, and the liftgate is armed individually, and if any are open, they must be closed before the open entry point (door, hood, or liftgate) can enter the 20 second countdown. The turn signal lamps will flash once when all doors, the hood and the liftgate 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. • Turn ignition to the on position with a valid programmed 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. • If using a key in the driver's door to unlock the vehicle, a chime will sound when you open the door and you will have 12 seconds to disarm the alarm system using any of the actions above, otherwise the alarm will trigger. 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 keypad or the remote entry transmitter portion of your IKT. • The ignition is turned to the on position with an invalid unprogrammed SecuriLock௡ key or IKT. 184 2010 Expedition (exd) Owners Guide, 3rd Printing USA (fus)
