OP, a question? When you place the batteries into the FOB case (2032's 2 each I believe), does the 'bottom' battery have a chance to, or is it possibly 'touching' the positive terminal at all? IF that is touching, the one battery on top will drain & the FOB just might be 'undervolted'. Since the FOB was opened/closed at least once (maybe even more), that 'positive' terminal coming up and around the batteries may have bent inwards some? You might have already checked that but if by pressing the battery cover on, could it maybe push over and short that top battery (I do not think there is enough 'current' in those 2032's to actually heat up that much so you might not have noticed a warm case). IF there is a possibility of the upper terminal that comes around that bottom battery is touching, then you will have to find a way to prevent that from happening (and check if either battery is dead). I know you said the batteries are new but..... Good luck!
