I have a garage door from Craftsman Model 139.53664SRT2. I was having trouble with the remotes only working in a short distance and the keyless pad would not work at all. I tried new batteries and reprogramming the remotes, however, when I try to reprogram, nothing happens. The unit never blinks to show that it has reprogrammed. Now, the remote will not even work at a short distance. Any suggestions?

yes, i did hold down the remote button and then the red button on the power head, but it doesn't do anything. It is suppose to blink after a few seconds when it is programmed. The yellow light goes on when you press the button. It stays on for a minute and then goes off. There is an antenna wire as well
thanks, that is what i was thinking as well.
