I love the keyless entry! Never had this before and it makes me smile whenever I use it. Last week I couldn't locate either of my FOBs. (unfortunately, this is not unusual - but that is another story). Anyway, I was able to locate it finally when I walked up to the car with one of my equipment packs in hand. When the door responded, I knew it was in that pack. The more interesting thing I discovered was that the other FOB was in the pocket of my jacket inside the car. Not thinking that it is a good idea to allow the doors to shut - locked with the key inside, I looked this feature up in the manual. If I understand correctly, if you leave the car with locked doors and the car detects only one FOB - and that FOB is inside the car, then the doors will unlock within a few seconds, and the car will chirp at you. Since I had a locked car with a FOB inside, I concluded that the car must have detected the other FOB in the pack in my hand when I left the car. Still - love that keyless entry feature!
