gsxr, OK explain this away. My granddaughter's husband programmed my '97
CL500 in a couple of minutes. I have a relatively new Chamberlain opener with rolling codes. We used the Austin MB video as a guide.
I upgraded to a '97 CL600 and I can't program it! Unfortunately Matt lives 1500 miles from me!
