Check MyKey™ System Status
The vehicle System Check will provide the status of the following
MyKey™ parameters:
•MYKEY MILES — This odometer only tracks mileage when a MyKey™
is used. If mileage does not accumulate as expected, then the
MyKey™ is not being used by the intended user. The only way to
reset this odometer to zero is by disabling MyKey™. If this odometer
is lower than the last time you checked, then the MyKey™ system has
been recently cleared.
• # MYKEY(S) PROGRAMMED — Indicates how many MyKeys™ are
programmed to the vehicle. Can be used to detect deletion of a
MyKey™.
• # ADMIN KEYS PROGRAMMED — Indicates how many Admin keys
are programmed to the vehicle. Can be used to detect if an additional
spare key has been programmed to the vehicle
Refer to Message center in theInstrument Cluster chapter for MyKey™
system warnings displays.
Using MyKey™ with Remote Start Systems
MyKey™ is not compatible with non-Ford approved aftermarket remote
start systems. If you choose to install a remote start system please see
your authorized dealer for a Ford approved remote start system.
When using a Ford-approved remote start system, the default settings
will recognize the remote start system as an additional Admin Key with
its associated privileges. You should program the remote start system as
a MyKey™ in addition to the key that you have already programmed as a
MyKey™. To program the remote start system as MyKey™, do the
following:
1. Enter the vehicle and close all doors.
2. Remote start the vehicle using a remote start fob.
3. Follow steps 1-4 in the Create a MyKey™section.
Note: For all vehicles, the number of MYKEY(S) PROGRAMMED or
ADMIN KEYS PROGRAMMED that is displayed in the MyKey™ System
Status menus will include the remote start system as an additional key in
the total count. See the Check MyKey™ System Status section.

PERIMETER ALARM SYSTEM (IF EQUIPPED)
The perimeter anti-theft system will help protect your vehicle from
unauthorized entry.
If there is any potential perimeter anti-theft problem with your vehicle,
ensureALL Integrated Keyhead Transmittersare brought to the
authorized dealer to aid in troubleshooting.
Arming the system
When armed, this system will respond if unauthorized entry is
attempted. When unauthorized entry occurs, the system will flash the
turn signal lamps and will sound the horn.
The system is ready to arm whenever the key is in the off position, or is
removed from the ignition. Either of the following actions will prearm the
alarm system:
•Press the
control on the remote entry transmitter portion of your
Integrated Keyhead Transmitter.
When you press the lock control twice within three seconds on the
remote entry transmitter portion of your IKT, the horn will chirp once
to let you know that all doors, the hood and the liftgate are closed. If
any of these are not closed, the horn will chirp twice to warn you that
a door, the hood or the liftgate is still open.
•Press the driver or passenger
interior door lock control while
the door is open, then close the
door.

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
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.
•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 on position with a valid SecuriLockkey 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 on position with an invalid SecuriLock
key or IKT.
