Wall unit to garage opener is fine. replaced battery but remote is not working at all.
You will need to train (link) the remote to the garage door opener. to do this you will need to find the remote "train" button on the operator.
If you have the manual for the garge door opener this will show you where it is located.
push the train button on the operator, an LED light will start blinking. Then push one of the buttons on the remote. the LED light on the operator will stay on. push the button on the remote again and the light on the operator will turn off.
try the remote it should work now.
Sorry for the dely in getting back with you.... You noted the door operator was an older Craftsman product, correct.. How old is it? Around '96 regulations passed that the operators had to have safety eye at the bottom of the doors. the codes for the transmitters aslo changed about that time to a "Home code 2" series. If it was placed in survace before '96 Depending on its age the unit may not function with the newer remote transmitters. Therefore you may have a problem finding a newer universal transmitter that works. My best suggestion if you can't get it to program then you may need to replace it with the same model from Sears service center.

COULD BE A BAD REMOTE, I WOULD TRY ANOTHER ONE FIRST.
COULD BE A FREEZER ETC. PUTTING OUT INTERFERENCE.
OR
Anytime a door opens and/or closes randomly or doesn't work consistently I look for a smashed wire between the motor unit and the wall button.
If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.
Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.
The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone

I did the learn button for the remote and it still doesnt open the garage door. The remote will work when you are inside the garage, but when you are outside pulling up in the car it doesnt work
Thank you very much. I tired to pushing the train button, but the LED light only stayed on. When I pushed the button on the remote nothing happened. THis was a remote that, even when it was working, did not consistently work. Maybe the remote in no good. Do you know where I can find a "universal remote" that may work on this old craftsman product? Buy the way the door unit is fine and so is the remote on the other garage door.
