Can't program two. When I get one to work the other fails. When I program the second one so it works, the first one fails.

I have three, the third one was the recent one for my son's truck. When I programed his, I also reprogramed the other two. Push the button on the back of the liftmaster, until it blinks. Program each one at a time. That should fix it.

I had the same problem... then I completely read the instructions lol... open the back of the remote and the little white tabs need to be the same in both remotes.

Strange. I purchased two for use with a Sears opener and they both worked fine. Sounds like something to do with the receiver?Have you tried changing the code on the opener and resetting the remotes to that code?

I have 2 garage doors so I had to buy 2 separate remotes. Each door has a different programming.

Depending on the model of your opener it may only accept one code switch setting so all the remotes need to be set to the same code. Id the code switches are different only the last one learned will work.

If you do not have 2 keys that already work you will not be able to program 1 new key. I had a local moble locksmith cut new key and program .

I had the same problem. I had to reprogram my old remote too and did it a couple times before both of them worked.

My first timer didn't do anything strange and is working very well. The second one I bought did something weird, similar to what you're describing but I can't remember exactly what it was. This second one has not worked correctly since the day I got it. It's on the same table as my wireless phone and whenever I put the phone back in the holder the timer loses it's programming. Too much trouble to return and get a new one so I live with it.

I couldn't get mine to program either so I took place guts out of my old one and it worked

No, can only program one at a time. It saves your original program so you would have to go back to stock in order to start programming a different vehicle.

First, make sure BOTH plugs are plugged in. Mine won't work with only one. The only other thing I can think of would be to restart with it connected. Unless you're running Linux. If so you probably have to mount it.

I have no idea, they send 2, but only one worked, and that only after a dealer programmed it.

There are 2 Roku codes that can be programmed. You are using the wrong one. Program the other one. How do i know? I did the exact same thing. If the Return key (Go back key) works... then that should be the right code.

They should all open on 000. If two do and one doesn't, it sounds like someone changed the combination. Either try all the possibilities or send it back.

Yes, thats what I have. It worked fine after programming for several weeks. It then suddenly stopped working but I believe its related to a different problem.

Yes. I was able to program two openers with the same touch pad. The instructions indicate you can program for multiple openers, but does not indicate a limit to how many. In my case, I have two codes entered so that I can open one or the other door.

I'm not sure of your question. You have to program all fob's at the same time. So if one isn't working, reprogram all. Make sure the battery is good before you reprogram. That could the problem in your #1 key fob.

I couldn't get it to work either. I had the 1st one replaced ... and got the second one. Neither worked. Maybe I am stupid???????

You still have to go to the dealer for programming and only one of the two I bought worked. Save time and hassle and just buy one from the dealer

Yes, I've only ever had one and it died. I ordered this skeptically, but when I received it, it took no longer than 2 minutes to program. It will come with a set of instructions and if you follow those to a T, you should be good to go.
