1996 Oldsmobile 88 Remote Keyless Entry Problems

1996 Oldsmobile 88 Remote Keyless Entry Problems (I just a bought used 88 without manual)

I believe there may have been a recall for this problem so I am going to a dealer to find out more about it.

Only the back doors will lock or unlock with the remote and I am having difficulty figuring out the alarm system (the horn goes off at different times when opening the door).

Does anyone know the answers?

You might have better luck getting an answer if you post this in the Olds forum and not the caravan one. :)
