KEYS
Your vehicle is equipped with two
Integrated Keyhead Transmitters
(IKTs). The key blade functions as a
programmed key which starts the
vehicle and unlocks/locks all the
doors. The transmitter portion
functions as the remote entry
transmitter.
Your IKTs are programmed to your vehicle; using a non-programmed key
will not permit your vehicle to start. If you lose your authorized dealer
supplied IKTs, replacement IKTs are available through your authorized
dealer. Standard SecuriLockkeys without remote entry transmitter
functionality can also be purchased from your authorized dealer if
desired.
Always carry a spare key with you in case of an emergency.
For more information regarding programming replacement IKTs, refer to
theSecuriLockpassive anti-theft systemsection later in this chapter.
Note:Your vehicle’s IKTs were
issued with a security label that
provides important vehicle key cut
information. It is recommended that
you keep the label in a safe place
for future reference.

Replacing the battery
The integrated keyhead transmitter uses one coin type three-volt lithium
battery CR2032 or equivalent.
To replace the battery:
1. Twist a thin coin in the slot of the
IKT near the key ring in order to
remove the battery cover.
Note:Do not wipe off any grease on
the battery terminals on the back
surface of the circuit board.
2. Remove the old battery.
Note:Please refer to local
regulations when disposing of
transmitter batteries.
3. Insert the new battery. Refer to
the instructions inside the IKT for
the correct orientation of the
battery. Press the battery down to
ensure that the battery is fully
seated in the battery housing cavity.
4. Snap the battery cover back onto
the key.
Note:Replacement of the battery willnotcause the IKT to become
deprogrammed from your vehicle. The IKT should operate normally after
battery replacement.
Replacing lost Integrated Keyhead Transmitters (IKTs)
If you would like to have your Integrated Keyhead Transmitters
reprogrammed because you lost one, or would like to buy additional
IKTs, you can either reprogram them yourself, or takeall IKTsto your
authorized dealer for reprogramming.
How to reprogram your Integrated Keyhead Transmitters (IKTs)
To program a new Integrated Keyhead Transmitter yourself, refer to

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.

position, the indicator will flash
once every two seconds to
indicate the SecuriLocksystem
is functioning as a theft
deterrent.

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

position.
The theft indicator will flash every
two seconds to act as a theft
deterrent when the vehicle is
armed.

position.
The theft indicator will illuminate for three seconds and then go out. If
the theft indicator stays on for an extended period of time or flashes
rapidly, contact your authorized dealer as soon as possible.
