FORD 2013 F-550 v.1 - Manual (Page 76)

SECURILOCK® PASSIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
Note: The 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: Metallic objects, electronic devices or a second coded key on the
same key chain may cause vehicle starting issues if they are too close to
the key when starting the engine. Prevent these objects from touching
the coded key while starting the engine. Switch the ignition off, move all
objects on the key chain away from the coded key and restart the engine
if a problem occurs.
Note: Do not leave a duplicate coded key in the vehicle. Always take
your keys and lock all doors when leaving the vehicle.
The system is an engine immobilization system. It is designed to help
prevent the engine from being started unless a coded key programmed
to your vehicle is used. Using the wrong key may prevent the engine
from starting. A message may appear in the information display.
If you are unable to start the engine with a correctly coded key, a
malfunction has happened and a message may appear in the information
display.
Automatic Arming
The vehicle is armed immediately after switching the ignition off.
Automatic Disarming
Switching the ignition on with a coded key disarms the vehicle.
Replacement Keys
Note: Your vehicle may come equipped with two integrated keyhead
transmitters.
The integrated keyhead transmitter functions as a programmed ignition
key that operates all the locks and starts the vehicle, as well as a remote
control.
If your programmed transmitters or standard SecuriLock coded 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.
Store an extra programmed key away from the vehicle in a safe place to
help prevent any inconveniences. See your authorized dealer to purchase
additional spare or replacement keys.
