Does anyone know how to program keyless entry transmitter for a 1990 Olds Cutlass Supreme SL?

Wish someone would answer this, cause I too have this problem. When I got my car 4 years ago it worked but after a year it stopped working. Went through 3 or 4 batteries in my "controller" until i realized it was the programming.

I saw this site on another thread
