Sounds like it's got a "learn" mode where you set something, hit the button on remote #1, then remote #2, and it's supposed to remember them both.
Apparently it will remember one or the other, but not both at once.
Of course, knowing the model number of the opener would help, since there's hundreds of "how to program" pages out on that there InterWebby thing, but we don't know which one applies.

When you got the opener from Sears you got a manual with it. In that manual there is a 800 number for trouble shooting. Call that number during weekday business hours and they will walk you through it. If you can not find the number look on the website for Chamberlain (that's who made the opener for Sears) and they will walk you through it. They did for me and solved my problem.

I have Sears remote for opening our garage door. We had to buy a second one a few years ago. Ours works well but before ordering we had to give them the # of the old one.
Did you check your batteries in your remote opener?

Push the smart button momentarily (do not hold it), push one of the transmitter buttons within 30 seconds. Push the smart button again momentarily & push the other transmitter button within 30 seconds.
Holding the smart button (as some directions say to do) for more than 10 seconds (smart button LED goes out) erases the memory. If you have to erase the memory to get the second transmitter to work, the transmitters are not compatible. One is rolling code & one isn't. It's possible for a transmitter to lose its rolling code capability & if it does it's non-repairable & needs to be replaced.
