Lacrosse I have a 2010 Buick Lacrosse and the trunk hood keeps coming up on its own. Why and how do you fix that problem

Is your remote in your pocket? I keep mine in with my other keys, and my brothers car starts because some thing in his and my pocket keep pushing the buttons to open it. make sure that the release in the glove compartment doesn`t have any thing up against it like paper between the door and the button.
