available from your authorized dealer. You can also create up to three of
your own 5–digit personal entry codes.
Note:If your vehicle is equipped with the intelligent access feature, your
keypad will still function normally if you enter your personal entry code
or factory set code. However, if your transmitter is within range of the
driver’s door, an intelligent access unlock will also occur each time you
press any number on the keypad. Note that this additional unlock will
not impact keypad functionality, and you can still enter your code and
perform all keypad functions (unlock, lock, trunk release).

SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLockpassive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless acoded intelligent access keys programmed to your
vehicleis used. The use of the wrong type of coded key may lead to a
“no-start” condition.
Your vehicle comes with two coded intelligent access keys; additional
coded transmitters may be purchased from your authorized dealer. The
authorized dealer can program your spare transmitters to your vehicle or
you can program then yourself. Refer toProgramming spare intelligent
access keysfor instructions on how to program the coded key.
Note:The SecuriLockpassive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
Note:Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded key and restart the engine.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.
