Car Alarm/ Multiple Fixes

I’ve got this dreaded 3G car alarm issue where it randomly goes off for no apparent reason. I’m at my wits end. I’ve searched this forum for weeks to come up with the fixes I’ve completed thus far. I read how one guy simply sold his car. He was that sick of the problem. I laughed. I’m not laughing anymore.

What I’ve replaced with new parts so far:

* Power door lock actuators in all 4 doors
* All 4 black “dome light” switches in door jams
* New trunk lock/latch
* New hood lock/latch

At this point it’s becoming an issue of what’s the car really worth. If it costs $1,500 at the dealer to diagnose it then forget it. Consider it one more TL going to the scrapyard. Other than this the car is in perfect shape but I cannot have the cops called on me every night (and I can’t leave my doors unlocked), and I can’t have it going off at work anymore. Security is pissed.

What else is there? I’m tired of throwing money and parts at it with no real idea for what the reason is. So far a lot of people have ideas about how to fix it from reading the forums but these people haven’t really had the problem themselves.

Any help is extremely appreciated!!! I’m tired of disconnected the negative battery terminal everywhere I go. I thought of putting a kill switch in it... but one shouldn’t have to do that and it’s pretty extreme.
