I have a 2000 Bonneville. The Security light was on for a few weeks then it went out. Now when I unlock and open the driver's side door with any of my keys the car the alarm goes off. I can turn the alarm off by starting the car, but how do I get it to stop doing this? Frustrated!

I'm wondering if the switch in your door is bad. When you insert and turn the key, it activates a switch that disables the alarm. Other possibilities include bad wiring from the switch into the car or perhaps a fault with the anti-theft system. Do you have a key fob for this car (there were a few that didn't come with this option)?

As I recall, the 2000 model year still had a key cylinder in the passenger door as well. What happens when you open that one with the key?

I believe you can lock the door manually (push the lever down) without using power locks and it never sets the alarm.
