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.
THEFT INDICATOR
The theft indicator is located on top of the instrument panel.
•When the ignition is in the OFF position, the indicator will flash once
every 2 seconds to indicate the SecuriLocksystem is functioning as
a theft deterrent.
•When the ignition is in the ON position, the indicator will glow for 3
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, the vehicle should be taken to an authorized dealer for service.
Automatic arming
The vehicle is armed immediately
after switching the ignition to the 1
(OFF) position.
Automatic disarming
Switching the ignition to the 3 (ON) position with acoded keydisarms
the vehicle.
Key information
Your vehicle is supplied withtwo coded keys.Only acoded keywill
start your vehicle. Spare coded keys can be purchased from your
dealership. Your dealership can program your key or you can“do it
yourself.”Refer toProgramming spare keys.
Certain items may cause vehicle starting issues:
•Large metallic objects
•Electronic devices on the key chain that can be used to purchase
gasoline or similar items

Locks and Security

•A second key on the same key ring as thecoded key
If any of these items are present, you need to keep these objects from
touching thecoded keywhile starting the engine. These objects and
devices cannot damage thecoded key,but can cause a momentary“no
start”condition if they are too close to the key during engine start. If a
problem occurs, turn ignition OFF and restart the engine with all other
objects on the key ring held away from the ignition key. Check to make
sure thecoded keyis an approved Fordcoded key.
If your keys are lost or stolen you will need to do the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to a dealership or a locksmith. The key codes
will need to be erased from your vehicle and new key codes will need
to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correctcoded keymust be used for your vehicle. The use of the
wrong type ofcoded keymay lead to a“no start”condition.
If an unprogrammed key is used in the ignition it will cause a“no
start”condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLockkeys can be used. To program acoded keyyourself, you
will need two previously programmedcoded keys(keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure before you begin.

in 3 (ON) for at least one second,
but no more than ten seconds).
2. Turn ignition to 1 (OFF) then 2
(ACC) and remove the firstcoded
keyfrom the ignition.
3. Within ten seconds of removing
the firstcoded key,insert the second previously programmedcoded

(maintain ignition in 3 (ON) for at least one second but no more than
ten seconds).
4. Turn the ignition to 1 (OFF) then 2 (ACC) and remove the second
coded keyfrom the ignition.

unprogrammed key (new key/valet key) into the ignition and turn the
ignition from 1 (OFF) to 3 (ON) (maintain ignition in 3 (ON) for at least
one second, but no more than ten seconds). This step will program your
new key to a coded key.
6. To program additional new unprogrammed key(s), repeat this
procedure from step 1.

theft indicator will illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start the vehicle’s engine
