FORD 2003 F-150 v.1 - Manual (Page 87)

• 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 RUN 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 RUN 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 and key codes
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.
