When parked, I cannot lock my doors because the slightest movement (e.g. breeze) causes the factory installed car alarm to go off!!! Any advice is much appreciated!!!!!
While sitting inside w/the door closed, push outward on the door to see if the dome light comes on. If it does, you can adjust the striker in the door jamb inward to make the door close tighter. Sometimes the seals get old and cause this, sometimes it's the hinges.
If the light doesn't come on when pushing drivers door, repeat with each door until you find the culprit. I "fixed" one like this and it was the drivers door. It didn't have any play in the hinges either. I just moved the striker in a little, it tightened up the seal and problem went away.
And Welcome to CF.
