On my94, my switch needed to be raised a bit so I found this clip that happened to fit right in there and it raised it up and then it was tightened. That worked for a while and then it started again. I jerked all of that stuff out of it and never heard it anymore unless I pushed "lock" on my remote twice real fast.
My 95 done it a few times and it turned out to be bad door jamb switches that were making my interior lights come on. Voltage draw would set it off. Since replacing the door jamb switches, the 95 hasn't done that anymore. When it does start again, the module will be pulled out of the car. If a real thief was going to steal it or get something out, that almost 2 decade technology isn't going to keep them out. It's not hard to get in a Mark with a factory alarm. Ever looked under the front of your bumper cover? The horns are right there to be unplugged. I disconnected mine about 3 years ago and installed a 147db siren and connected that to my horn and made the wires unreachable.
