Look up in the passenger footwell near the glovebox/kick panel/carpet corner area. If you have keyless, there will be a white plug there, wrapped with black tape. That is the programming plug for the keyless entry. My sister's 1995 Mystique GS and my 1998 LS had it. If you (hopefully!) have that plug, there is a way to test the keyless. Then you can get remotes on e-bay.
