Does it pop open while you're driving? Not like all the way, but where the inside lights would come on? I had this problem awhile ago mine was pulling it in too but when it pulled in it would also push out slightly and cause it to open over bumps. I had to leave my rig at my friends shop for a day and he ordered a new latch key for the back ripped the panel off installed it and now I have no issues. I will say he said it was from off roading it's a bit rocky around me and on stock suspension it caused the thing to malfunction from bumping up and down so much
