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 integrated keyhead transmitter (IKT)
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 integrated keyhead transmitters;
additional coded IKTs may be purchased from your authorized dealer.
Standard SecuriLockkeys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired. The authorized dealer can program your spare IKTs to your
vehicle or you can program the IKTs yourself. Refer toProgramming
spare 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 IKT while starting the engine. These
objects will not cause damage to the coded IKT, but may cause a
momentary issue if they are too close to the IKT when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded IKT 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.
Anti-theft indicator
The anti-theft indicator is located in the instrument panel cluster.
•When the ignition is in the off
position, the indicator will flash
once every two seconds to
indicate the SecuriLocksystem
is functioning as a theft
deterrent.
•When the ignition is in the on position, the indicator will glow for
three seconds to indicate normal system functionality.
If a problem occurs with the SecuriLocksystem, the indicator will flash
rapidly or glow steadily when the ignition is in the on position. If this
occurs, turn the ignition off then back to on to make sure there was no
electronic interference with the programmed key. If the vehicle doesn’t
start, try to start it with the 2nd programmed key and if successful
contact your authorized dealership for key replacement. If the indicator
still flashes rapidly or glows steadily, the vehicle will not start, contact
your authorized dealer as soon as possible for service.

Automatic arming
The vehicle is armed immediately after switching the ignition to the off
position.
The theft indicator will flash every
two seconds to act as a theft
deterrent when the vehicle is
armed.
Automatic disarming
The vehicle is disarmed immediately after the ignition is turned to the on

Replacement of integrated keyhead transmitters (IKT) and coded
keys
Note:Your vehicle comes equipped with two integrated keyhead
transmitters (IKTs). The IKT functions as both a programmed ignition
key that operates all the locks and starts the vehicle, as well as a remote
keyless entry transmitter. A maximum of eight coded keys can be
programmed to your vehicle; only four of these eight keys can be IKTs
with remote entry functionality.
If your IKTs or standard SecuriLockcoded keys are lost or stolen and
you don’t have an extra coded key, you will need to have your vehicle
towed to an authorized dealer. The key codes need to be erased from
your vehicle and new coded keys will need to be programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
You can program your own integrated keyhead transmitters or standard
SecuriLockcoded keys to your vehicle. This procedure will program
both the engine immobilizer key code and the remote entry transmitter
portion of the IKT to your vehicle.Note:A maximum of eight coded
keys can be programmed to your vehicle; only four of these eight can be
IKTs with remote entry functionality.
