yea...buy any ford or startec blank with a chip....like the one in the above post, got to home depot, have it cut. Then:
Put the first working key in the ignition, turn it to run, then wait for the "theft" light to go out.
Immediatly remove the key, put in the second working key, turn it to run, then wait for the theft light to go out.
Immediatly therafter, insert the new cut/unprogramed key, then turn it all the way to start and crank till the engine catches.
You have sucessfully programed a 3rd key.
NOTES:
-You can only program a max of 4 keys per car.
-If you have a model past-1997, you need only one key to program another, just remove step 2 above.
-If it is a 1998-current model, you MUST have 2 working keys. If you dont you need to go to the dealer to program the 2nd key.
