ANY TIME YOU CHANGE THE BATTERY IN A REMOTE IT NEEDS TO BE REPROGRAMED.

ON THE CIRCUIT BOARD YOU WILL FINS A SQUARE BUTTON.

Keep the remote that works with the keypad and replace the other remote with one of the same model. This is a common problem and the only cure is replacement.

Cant get 2 remotes for garage door openers working at same time


You have a remote that has reverted to an earlier technology. The only way out of this is to purchase the same exact model number called for by your opener and go through the programming. You will find the new one will work with one of the old ones. Remove the battery from the one that isn't and drop it in the garbage.

Remote doesn't work!!!


You could try to replace batteries. May be they are stong enough to make the LED flicker, but not strong enough to send out a proper signal to the receiver.

Craftsman garage door opener remote failure


You may be receiving interference. Take all the batteries out of the remotes and try them one by one. You will not have to reprogram them. If you find one shortening the range of the others then get rid of it. Or it may be an outside source. Worst case is you will have to replace the logic board. Thanks BB
