NO, I don't think that is it, it uses RFID to lock and unlock, it's a one way thing, the car doesnt check to see if the key is in range, only when you press the button does the key do it's thing, I don't exactly understand how the RFID works per se, but that should not run your battery down.
What I know will fail it, if your key is in your pocket and your cellphone is in the near vicinity, like in the same pocket, you will often get a "can't find remote" error or the comfort start wont work.
When I stopped putting the keys in the same pocket, never happened again
(again 1'er CA)
Also when your in the car one of 3 aerials need to detect the key for example if the key is OUTSIDE the cabin, wont start.
That could be a problem, but try the key without phone sceranrio
just a thought, the "KEY" could be faulty, perhaps the membrane in the key is making a circuit too easily, so when you key is upside down, in your pocket etc it's making contact, if your brave, take it apart and clean the membrane and check all the contacts, also try a new key

Then I read that the distance from FOB to car may be an issue (as I leave all my keys just inside the door that leads to the garage) and that this may drain FOB battery. So I replaced battery again and now take my keys upstairs. Coming up on 2 weeks so I'll see what happens.
