So we ended up buying a 2014 Expedition Limited. The vehicle came with one key, as usual, with the fob head for lock, unlock, tailgate/trunk and panic buttons. In this MY I understand there were sometimes dealer-installed remote start systems. I noticed the presence of a hood open detection switch and wasn't sure if it was factory installed and for some other purpose than remote start or is this possibly an indication that the remote start exists but all the add-on fobs are long-lost?
