The 94 GT Vert I picked up last month came with a single key. Is it possible the car came equipped with a remote key fob originally? Factory manual states its an option. Is there a quick way to tell?
Look behind the trunk panel on the driver side, you should see a 2 wire grey plug that is not connected.
If the plug is there then you have key less entry. You can also check youtube to see how to program the FOB.
