PASSIVE ANTI-THEFT
SYSTEM
Note:
The system is not compatible with
non-Ford aftermarket remote start systems.
Use of these systems may result in engine
starting problems and a loss of security
protection.
Note: Metallic objects, electronic devices
or a second coded key on the same key
chain may result in vehicle starting
problems, especially if they are too close to
the key when starting your vehicle. Prevent
these objects from touching the coded key
when starting your vehicle. Switch the
ignition off, move all objects on the key
chain away from the coded key and restart
your vehicle if a problem occurs.
Note: Do not leave a duplicate coded key
in your vehicle. Always take your keys and
lock all doors when leaving your vehicle.
SecuriLock®
The system helps prevent the engine from
starting unless you use a coded key
programmed to your vehicle. Using the
wrong key may prevent your vehicle from
starting. A message may appear in the
information display.
If you are unable to start your vehicle with
a coded key, it is not operating correctly.
A message may appear in the information
display.
Automatic Arming
The system arms when you switch the
ignition off.
Automatic Disarming
The system disarms when you switch the
ignition on with a coded key.
Replacement Keys
Note: Your vehicle comes with two keys. The integrated keyhead transmitter
functions as a programmed ignition key
that operates all the locks and starts your
vehicle, as well as a remote control.
The intelligent access key functions as a
programmed key that operates the driver
door lock and turns on the intelligent
access with push button start system, as
well as a remote control.
If your coded keys are lost or stolen and
you do not have an extra coded key, you
need to erase the key codes from your
vehicle and program new coded keys.
Contact an authorized dealer.
Store an extra programmed key away from
your vehicle in a safe place. You can
purchase replacement keys or remote
controls from an authorized dealer.
Programming a Spare Integrated
Keyhead Transmitter
Note:
You can program a maximum of four
keys to your vehicle. All six can be
integrated keyhead transmitters.
You can program your own integrated
keyhead transmitter or standard
SecuriLock coded keys to your vehicle.
This procedure programs both the vehicle
immobilizer keycode and the remote
control to your vehicle.
Only use integrated keyhead transmitters
or standard SecuriLock keys.
You must have two previously
programmed coded keys and the new
unprogrammed key readily accessible.
Contact an authorized dealer to have the
spare key programmed if two previously
programmed keys are not available.
Read and understand the entire procedure
before you begin.
1. Insert the first previously programmed
coded key into the ignition.

you are still unsuccessful, take your vehicle
to your authorized dealer.
Programming a Spare Intelligent
Access Key
Note: Do not place the device on the
wireless accessory charging area when

your vehicle and the new unprogrammed
intelligent access key readily accessible.
Contact an authorized dealer to have the
spare key programmed if two previously
programmed keys are not available.
