Anti-Theft System - Ford F-150 Owner's Manual

Locks and Security
SECURILOCK PASSIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
SecuriLock passive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless a coded key programmed to your vehicle is used. The
use of the wrong type of coded key may lead to a "no-start" condition.
The message center will display: STARTING SYSTEM FAULT.
Your vehicle comes with two coded keys; additional coded keys may be
purchased from your authorized dealer. The authorized 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.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.
Automatic arming
The vehicle is armed immediately after turning the ignition off.
Automatic disarming
Switching the ignition on 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.
