If this is an older garage opener, the inside of the remote and the wall unit have dip switches that must be set exactly alike (these remotes were famous for moving dip switches). Simply take the cover off the remote and the wall unit and look at the position of the switches (they are numbered 1 to...). Remember they must be exactly the same. If this does not help then you will be forced to go to Sears and pray that someone there knows something about the product they sell. True to their reputation they will probably tell you to send for one of their servicemen and then you will have a decision to make. I hope this helps you and you will not have to go that route. GOOD LUCK!!!

Thanks for your help. I took the remote opener apart and there are no dip switches that I can find. The garage door opener must be a newer version. If you have any other thoughts please send them my way. If I don't hear back I will try calling Sears (ugh!) to see if they can help. Thanks again for responding.
