I've got an 03 civic ex 4 door. It's been crashed before. When I close the drivers side door the alarm goes off sometimes if I pull on the door it'll stop. What's the easiest fix for this. Could someone tell me where the relay for the alarm is so I could pull it. Or if there is some wire on the car I could just cut so I can still use my remote to lock and unlock the car. Also what precautions do I need to know to keep the air bag from being triggered.

Thanks for the help in advance.
