I have a 08 GP base and my alarm has gone off a couple times on me. it has something to do when you lock it from the inside or with a key fob, and unlock it by pulling the thing that shows if its locked or unlocked and then opening the door. once I had my car lock but windows rolled down (smart idea eh?) and I wanted to open the door but it was locked and I didn't feel like grabbing my key from my pockets so I just unlocked it by pulling the stick and opened the door, next thing you know it was honking and flashing the lights, so I ended up getting my keys out and calming it down lol
