I was referring to your key fob and had the same issue in that pressing the open/close button did not work and so you had to touch the handle to open the car. Not sure how you would put a trickle charge on a key fob. You should also note when you start the car you will get a message in the instrument cluster to say the key fob has a low battery and in my case at the end that it had completely run out.
