yea, i have tones popper kit installed and the pin switch which will set the alarm off.. what i meant was that when you press the 'unlock' button on the remote, the alarm knows you are opening the doors, so it disarms... the option button doesnt do that to my knowledge, so the rear door would open, but the alarm would still be active.. so if you used the option button to pop the rear door, it would set the alarm off unless you had already unlocked the front door(s) using the remote
