I'm posting this because I can't find this information anywhere else. My simple question is "Where is the FOB's built-in key used?" My Honda salesman didn't know. The owners manual on page 564 shows it being used, and has a picture, but I couldn't tell the location from that closeup, and the description simply says "Insert key and turn clockwise." Really!?!? Insert key and turn! Wow! I have never used a key before. Is that how they work? The location of the key hole to open the trunk without the FOB is behind the rear headrest on the driver's side. I'm sorry, if this is common knowledge and obvious. It wasn't to me.
