I've searched far and wide and can't seem to find anyone with this problem. As soon as the key is out of the ignition the car begins to randomly arm itself. Horn beeps, doors lock. Random intervals but if the key is near the car it will continue to beep and lock.

I already re-soldered the battery tray, hoping that would fix the problem but no such luck. This is my GF's car that just moved from MA to TX. Her dad is a mechanic and couldn't get it fixed so I'm hoping you can help me be a hero.

Windows also don't roll down, but that is a different thread and wont be an issue until spring.

Thanks!
Matt
