Lets try erasing all old codes out and start fresh. Push and hold the colored learn button on the back or side of the motor unit until the led light goes out.-----Then press and release the same button and then press the button on the remote. The light bulb should flash once. For more remotes repeat from the ------. For a keyless entry press the learn button and the within 30 seconds press the 4 digit code followed by the up/down button. Again the light bulb should flash once. If they do not code or they still kick out then you need a new logic board. You can get one at sears.com, have the model number ready. Thanks BB

Same problem. I bought a 3rd remote. Erased all the codes. If I program the new remote first, the 2 old remotes won't program. I erased all the codes again. Programmed the 2 older remotes first without a problem, then the new one won't program All remotes have the same part number, but the date of manufacturing is about 9 years apart. Does that have anything to do with all 3 remotes not being compatable?

Btizzie one of your remotes has reverted to an earlier technology and the only way to fix this is to purchase a new remote. You will then find that you can program the new remote and one of the old remotes but not the other one. You should remove the battery from the defective remote and trash it. It will only cause problems down the road otherwise.
