FORD 2004 F-150 v.1 - Manual (Page 94)

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 keys for 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 top of the instrument panel.
• 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.
• 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 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.
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 a coded key disarms
the vehicle.
