We recently purchased a home with a 3 year old Craftsman Garage Door Opener. In-fact it was working just fine upuntil my 6 year messed with the "keyless" entry pad on the garage door jam. Since then neither one of the remotes will open or close the door and the instruction manual is NO help! Surprise! Yes both of us have attempted to follow the directions but resetting the system has not worked - any advice?
