Ford F-150 Heritage (2004 year). Manual — part 15

Note: The SecuriLock

娂 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 in the instrument cluster.
• When the ignition is in the 2 (LOCK) position, the

THEFT

indicator

will flash once every 2 seconds to indicate the SecuriLock

娂 system is

functioning as a theft deterrent.

• When the ignition is in the 4 (ON) position, the

THEFT

indicator will

glow for 3 seconds, then turn off to indicate normal system
functionality.

If a problem occurs with the SecuriLock

娂 system, the indicator will flash

rapidly or glow steadily when the ignition is in the 4 (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 3
(OFF) position.

The

THEFT

indicator will flash

every two seconds when the vehicle
is armed.

Automatic disarming

Switching the ignition to the 4 (ON) position with a coded key disarms
the vehicle.

• 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, have the system serviced by your dealer.

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娂 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.

2. Turn the ignition from the 3 (OFF) position to the 4 (ON) position.
Keep the ignition in the 4 (ON) position for at least one second, but no
more than 10 seconds.

3. Turn the ignition to the 3 (OFF) position.

4. Remove the previously programmed coded key from the ignition.

5. Within ten seconds of removing the previously programmed coded key,
insert the other previously programmed coded key into the ignition.

6. Turn the ignition from the 3 (OFF) position to the 4 (ON) position.
Keep the ignition in the 4 (ON) position for at least one second but not
more than 10 seconds.

7. Turn the ignition to the 3 (OFF) position.

8. Remove the previously programmed coded key from the ignition.

9. Within twenty seconds of removing the previously programmed coded
key, insert the unprogrammed key (new/valet key) into the ignition.

10. Turn the ignition from the 3 (OFF) position to the 4 (ON) position.
Keep the ignition in the 4 (ON) position for at least one second, but no
more than 10 seconds.

11. Your new, unprogrammed key is now programmed.

If the key has been successfully programmed it will start the vehicle’s
engine and the theft indicator light will illuminate for three seconds and
then go out.

If the key was not successfully programmed, it will not start your
vehicle’s engine and the theft indicator light will flash on and off, or stay
on for more than three seconds. If failure repeats, bring your vehicle to
your dealer to have the new key(s) programmed.

To program additional new unprogrammed key(s), repeat this procedure
from Step 1 for each additional key.

SEATING

Notes:

Reclining the seatback can cause an occupant to slide under the
seat’s safety belt, resulting in severe personal injuries in the

event of a collision.

Do not pile cargo higher than the seatbacks to reduce the risk of
injury in a collision or sudden stop.

Adjustable head restraints (if equipped)

Head restraints help to limit head motion in the event of a rear collision.
Adjust your head restraint so that it is located directly or as close as
possible behind your head.

The head restraints can be moved
up and down.

Push control to lower head restraint.
