Hello,
You will be able to tell if the lug nut has a key for it or not because it will be shaped differently from the other ones. To my knowledge, I don't believe that Ford Motor Company uses keyed lug nuts with their vehicle's, so if it is a keyed lug nut, it is more than likely that it is an aftermarket add on. You will have to figure out the manufacturer and go about getting a key that way, or cutting the lug nut and stud off with a rotary tool and punch the rest of the stud back through the rotor and replace them. I hope that this helps.
Thanks,
Alex
