Craftsman Garage Door Opener- cant program Keyless Entry
I have a fairly new ( 1.5 years old) Craftsman 1/2 HP Garage Door Opener ( model 130.53910). I have bought 3 Keyless Entry systems ( Security + with rolling code technology) as it says in the garage Door opener manual, followed the directions line by line and I could not get the Keyless entry to program? What could be the issue??
