oh! i thought you asked me how to shut that autopilot thingie off. ya see. the "autopilot" as i call it is on. so, when the alarm is "active", it will automatically arm 30 seconds after you close the door. you can "deactivate" the alarm using the 1-2-1 code on the keyfob, putting it in valet mode, but the alarm is still on autopilot. to shut off autopilot, you have to fiddle with the command center in the kick panel. then, the alarm will only activate when you hit button 1 regardless of whether or not the doors are open.
there's another neat feature when you can activate the alarm when the car is running. so if you are driving through a crappy area, you hit button one. alerts people if someone tries to carjack you because once a door is open, the alarm will sound. this resets when the car is turned off.
