FORD 2010 F-150 v.1 - Manual (Page 139)

Anti-theft indicator
The anti-theft indicator is located in the instrument cluster.
• When the ignition is in the off
position, the indicator will flash
once every two 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
three 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, turn the ignition off then back to on to make sure there was no
electronic interference with the programmed key. If the vehicle doesn’t
start, try to start it with the 2nd programmed key and if successful
contact your authorized dealership for key replacement. If the indicator
still flashes rapidly or glows steadily, the vehicle will not start, contact
your authorized dealer as soon as possible for service.
Automatic arming
The vehicle is armed immediately after switching the ignition to the off
position.
Automatic disarming
Switching the ignition to the on position with a coded key disarms the
vehicle.
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 an authorized dealer. 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.
