Hey body snatcher , have you ruled out the possibility of the buttons being pressed in your pocket while you are in the house or even a child In the house getn hold of the keys and pressing buttons , reason I mentioned this is my next door neighbors boot sometimes would open it's self and I one time witnessed it happen and also noticed that the hazards flashed a few times, when I went to say to him he came to the door with his little kid who had the car keys in his hand . Hope you get to the bottom of this
