Anyone running a key with a built in fob on it on their mustang or lightning? I've seen them on eBay but not sure if they work since we have that shroud thing on the ignition. I need a key and fob for my bullitt and thought that would be a cool way to go and would probably get one for the lightning as well if they work. I've sent guys with newer F-150's running the escape style key that is an all in one unit. Anyone have any experience with this that can give some insight? Some auctions on eBay say that it will work but I'm just not sure about it with the way our ignition is.
