2012 Ford F150My alarm goes off when I press the lock/unlock buttons on my fob. Sometimes the alarm goes off when unlocked or I can be walking up to the truck and it sets it off. Any advice would surely help. Thank you


RESPONSE

The vehicle is not operating at all like the standard ford PATS system, the alarm (lights and horn) should only go off in the event the panic button is pressed. This vehicle does not have a perimeter theft system. It just has a coded key.

You need to disconnect the negative battery cable for 10 minutes. Then reconnect. Now lock unlock the door with the remote key fob then use the key and do the same, now try starting it. if this fails to work then someone has installed something else in the vehicle incorporated with the ford standard system or you have a faulty PCM.

Remote Keyless Entry (RKE) Lock/Unlock Control — Unlock

The RKE feature provides lock/unlock functions independently of key position, vehicle speed, or transmission position. The RKE feature provides a stepped (if enabled) process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE feature requests the BCM to unlock the driver door only and provides a long flash of the turn signals. If another unlock request is received within 3 seconds of the first, the RKE feature requests the BCM to unlock all the doors. This feature can be configured to global unlock, so that all the doors unlock on the first press of the UNLOCK button. Refer to Stepped Unlock Programming in this section for programming information.

Remote Keyless Entry (RKE) Lock/Unlock Control — Lock

The RKE feature requests that all the doors be locked when the LOCK button is pressed. On any press of the LOCK button with all doors closed, the BCM provides one flash of the turn signals. If any door is ajar, no flash occurs. As soon as the last door is closed, the BCM provides the flash of the turn signals. If 2 presses of the LOCK button are received within 3 seconds, the horn chirps once and the turn signals flash twice to indicate that all the doors are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature requests the BCM to chirp the horn twice without flashing the turn signals to indicate all the doors are locked but one or more doors are ajar. When the key is in the RUN or START position, the turn signal flashes and horn chirp confirmations do not occur.

Panic Alarm

The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that the turn signals are flashed and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously. Activation of the panic alarm is accomplished by pressing the panic button on an RKE transmitter whenever the key is in the OFF position. At all other times this feature is disabled. Deactivation of an active panic alarm is accomplished by any of the following actions:

  • A second press of the RKE transmitter panic button
  • The key is switched out of the OFF position
  • A period of 2 minutes and 45 seconds has elapsed since the initial activation
