Locks and Security If not successful, the new coded key(s) will not start the vehicle's engine and you may repeat Steps 1 through 5. If failure repeats, bring your vehicle to your authorized dealer to have the new spare key(s) programmed. PERIMETER ALARM SYSTEM (IF EQUIPPED) The perimeter anti-theft system will warn you in the event of an unauthorized entry to your vehicle. If there is any potential perimeter anti-theft problem with your vehicle, ensure ALL remote entry transmitters are taken to the authorized dealer to aid in troubleshooting. Arming the system When armed, this system will respond if unauthorized entry is attempted. When unauthorized entry occurs, the system will flash the park/turn lamps and will sound the horn. The system is ready to arm whenever the key is removed from the ignition. Either of the following actions will prearm the alarm system: • Press the control on the remote entry transmitter. • Open a door and press the power door lock control to lock all the doors, and then close the door. • Press and hold the 7 • 8 and 9 • 0 controls on the keyless entry pad at the same time to lock the doors (driver's door must be closed). There is a 20 second countdown when any of the above actions occur before the vehicle becomes armed. Each door and the hood is armed individually, and if any are open, they must be closed before the open entry point can enter the 20 second countdown. The turn signal lamps will flash once when all doors and the hood are closed indicating the vehicle is locked and entering the 20 second countdown. 163 2012 F-150 (f12) Owners Guide, 2nd Printing USA (fus)
