Ok my remote control transmitter has been going bad for over a year now on my chapman alarm system. It is now totally out of commision. Soooo basicly, I can no longer start the car or anything. I did not have the alarm system installed, but I hear there is a valet switch somewhere that can disable the alarm? How do I find this? Does anyone have any pics of what it looks like? Or suggestions? Should I just have the vehicle towed to alarm shop and get a new alarm? Please help!
