CERTAIN Ford Vehicles have a 'corresponding other brand' that use the same key blank. Otherwise.. sorry. Mazda is the one I believe..
you got to go 'same brand' GEO is the same as the same model NEW Chevy's however they just 'rebranded' the Geo line. so its not different
Thats why I got 50 something GM blanks, 30+ Ford? and 20 ish Chryslers? Never mind the foreign.
