My '94 Regal has a wire in the trunk, just above the antenna. When that wire is grounded, the door locks and trunk release will cycle. I understand that this puts the system in program mode. Keep the wire grounded and press and hold "lock" and "unlock" on the remote (some say you need to press unlock only). You should hear the locks. Do both remotes at the same time. Unground the wire. In my case, sometimes the programming works and other times it doesn't. I suspect a receiver problem with mine, I just don't know where it is. I think that it may be under the dash/instrument cluster. There is an aluminum box with a number of cables attached. Some say, "don't mess with this or the air bag could deploy." Enough to scare me away, at least for now.
Anyway, mine does respond to this procedure ocassionally. There seems to be some well known procedures for 1997 and above but not much information for earlier model years.
Good Luck,
Ray
