Q: Why does my trunk and doors open on their own. on 2006 Buick LaCrosse

It was doing it once in awhile, now I get in the car and my trunk opens. I'll close it and get back in the car and it opens again. Sometimes 4 or 5 times. I can be driving and all my doors unlock then maybe relock and unlock again. The remote opens all 4 doors with one click. I removed the fuse, now I can't even open trunk because there isn't a lock on the outside.
