SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine immobilization
system. This system is designed to prevent the engine from being started
unless acoded key 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 keys; additional coded keys may be
purchased from your dealer. The dealer can program your spare keys to
your vehicle or you can program the keys yourself. Refer to
Programming spare keysfor instructions on how to program the coded
key.
Note:The SecuriLock
passive 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.
Theft indicator
The theft indicator is located on the instrument panel, above the hazard
flashers control.
•When the ignition is in the OFF position, the indicator will flash once
every 2 seconds to indicate the SecuriLock
system is functioning as
a theft deterrent.
Locks and Security

•When the ignition is in the ON position, the indicator will glow for 3
seconds, then turn off, to indicate normal system functionality.
If a problem occurs with the SecuriLock
system, 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.
Replacement keys
If your keys are lost or stolen and you don’t have an extra coded key,
you will need to have your vehicle towed to a dealership. 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 coded keys to your vehicle. Please read and
understand the entire procedure before you begin.
Tips:
•A maximum of eight keys can be coded to your vehicle.
•Only use Securilock
keys.
•You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
•If two previously programmed coded keys are not available, you must
take your vehicle to your dealer to have the spare key(s)
programmed.
1. Insert a previously programmed
coded key into the ignition.
