You may have a problem finding a Ford blank that works. i wanted a spare so i went to the Ford garage to get a spare cut and after looking for a while the guy realized they didn't have the right blank, so i went down the street to the Lincon/Mercury dealer and they cut one right away. Not saying you won't be able to get a Ford blank in our size, but you may have a problem.
Once it's cut and you give them about $20 then you program it yourself. Easy.
