factory keyless entry

hi, How can I tell if my 93 supreme has factory keyless entry.Thanks

From looking at the service manual for my car (92 cutty) it looks like the only way to really tell (correct me if i'm wrong) is if there is a remote reciever under the seat-to-back window trim panel. An easier tell-tale sign would be to look for a soleniod that would release the trunk latch. Just open the trunk and look right above the latch; It should have a switch and a label that reads "remote release lockout"
