Hi All. I have a 1993 Cadillac Sixty Special that has a non functioning remote. The remote is the original to the car which sat for 18 years in the original owners garage. After replacing the 2 batteries and having it tested it is transmitting but the car wont receive any signal from it. I talked to a Caddy dealer and they had no clue how to program an OLD Caddy. Does anybody know how I can program the remote to make it function as intended. All it has is lock, unlock, trunk release and panic button. Any help would be appreciated. Thanks.
