I have a 2009 Acura TL totally loaded? Only 230,00 KM  (I'm in Canada and watch you every day, especially in snowstorms). I saw your video on the  battery losing charge and came to think, I bet the second key fob is in the car trying to get read y to start. Either key fob for the car will let you start it even if the key is 6 feet away. it just waits for you looking all the time and that might be the intermittent  drain. second point on the key; there is a  slot  for it but in the slot is a switch that gets broken or stuck and won't let the key  lock or unlock. Very disturbing, but the friendly dealer  I took it to100 miles away, dealers are very scare and by order of Honda, stuck his finger in the slot and clicked the switch and BINGO. Keep on trucking, great to see someone  doing what you do.
