The local Walmart is now selling, cutting and programming keys for Ford vehicles.
$60 each.
I bought my last group of keys on E-bay for $10 ea.
Here you go;http://cgi.ebay.com/ebaymotors/ws/eB...tchlink:top:en
$7.99 ea.
$5.20 shipping for the first one additional keys ship free.

Buy a few so that you always have at least 2 in order to program additional keys.
I have one. My wife has one. There is one in the desk and my father in law has one that he can bring me if I get stranded.
That 4 for each of my 3 vehicles that use PATS keys.
I still have 2 blanks in the desk.
