So I've had this issue with my alarm since the day I bought the truck... I lock the truck, it beeps and the theft light comes (well came on when I had my old cluster) on acting like the alarm is set. Now here's my issue, when I lock the doors with the fob and open it from the inside, why doesn't my alarm go off? It does it on every other vehicle I have seen. It just doesn't arm apparently. It works when I hit the panic button on the fob, but not any other time. What's the issue?
