I just picked up a 2013 F-150 STX. It only came with one key and the lock cylinder on the driver's door sticks. I purchased an O'Reilly's key fob to carry as a spare "key" for the times I will lock the key in the truck.
Ever since I did this, when I step out of the building at work, my truck's alarm goes off instantly. Hitting the panic alarm on my ignition key will shut it off temporarily.
How do I shut the alarm off permanently?
