With Air (and I'm assuming Gravity), the problem is the key fob and/or mobile key communicate with the car from much further away than they unlock. They say hi, then they figure out how far away they are from each other before unlocking. So if your fob is far from your car, nothing is happening until you wiggle it, you're fine. If your fob is sitting in your entryway bin with your keys and wallet 20 feet from your car, it's regularly saying "are we close together yet? are we? are we? how about now?" It's not unlocking, but it is talking and draining its battery.
