It looks like you have the Pats 2 and are screwed if you only have one key.
My advice would be to call every Ford, Merc, Lincoln dealer within a
reasonable driving distance and get their price. When I needed a key for my
01, my local dealer wanted $75. The dealer 20 miles to the west only wanted
$35.
