Car Alarms: door locks/ car alarm going haywire, chevy blazer, paint primer

Question
I have a 97 Chevy Blazer with factory keyless entry, but an aftermarket alarm. For the past couple of days the door locks have been locking and unlocking on their own while driving and just sitting in the driveway. When I pulled the fuse it would activate the kill switch and I couldn't start my truck. I am tired of putting the fuse in to start the engine and then pulling it out after it is running. Can anybody help me out?

Answer
Find the alarm brain.  Trace the black wire to where it makes contact with the body.  This is the ground wire and it sounds like your ground connection is bad.  Disconnect the ground and clean the area it connects to of all paint/primer.  If the original installer put it to a factory bolt, move it to the kick panel.
