Garage door opener - Can only program one remote at a time

18 years ago

My father-in-law has a three year old Craftsman 1/2 HP garage door opener which had only one remote when he bought his home two months ago. The opener has a Smart Learn feature. I bought a new remote which I couldn't program until I reset all of the codes. I reprogrammed the new remote successfully, but the old remote wouldn't program. After erasing all of the codes again I successfully reprogrammed the old remote, but the new remote wouldn't program. Bottom line, I can only program one garage door remote and that's only after I erase all codes. Based on some of the other posts I've read, this problem may be in the logic board. Has anyone else ever had this problem?

You most likely purchased the wrong remote. There is no way to tell by looking but there are 2 technologies involved. Take the model number off the original remote or off the back of the motor unit to make sure you get the right one. It looks like 139.XXXXXSRTX.

The second remote works as long as it's the first one I program after I clear all of the codes. I can't even program the original remote if I make that the second remote I program after clearing the codes. The GDO just won't program two remotes no matter which one I program first.

Let's call these garage doors number one and number two. I think what you did was program one of the remotes from number one to number two or vice versa. This will cause that problem. What causes confusion is you are not programming the remote, you are teaching the receiver to accept the code from the remote. Now then what we need to do is go to each motor unit and hold the learn/smart button in for six seconds. This will erase the memory of both units and none of your remotes should work. Take the remote(s) you want to work with number one and press the button on the remote while you press and immediately release the learn/smart button on the motor unit. Do this for each remote you want to operate number one. Now do the same thing for number two. You should be okay.

Many apologies for the delay in sending this message. Have been out of town and only gotten back now. Bob -- My problem was I could program the first remote "A" and it programmed. However, remote "B" would not program. If I cleared all codes on the gdo and programmed remote "B" first, it programmed, but remote "A" would not program. No matter what remote I programmed first, "A" or "B" it would program, but the second remote would never program. The problem according to the technician was the 'rolling codes.' If the gdo is using 'rolling codes' and one of the remotes becomes defective and uses 'fixed coding' it will not program. His solution was to purchase new remotes and I am happy to report that his solution was correct. I purchased two new remotes. Both of these new remotes programmed. Of my two original remotes, one of them programmed, the other did not. The one that did not was the defective remote; i.e., the one that was using 'fixed coding.' I hope this helps. Chuck

We have two Craftsman 1/2 HP GDOs, with three-button remotes and keyless pads. (Model 139.53982SRT / Part 41A5483-2). One of the GDOs will not hold programmed codes on remotes or keyless for more than 24 hours. Hence, I use "learn / re-set" process each time we leave the garage on that side. Any hints to repair, or just time to replace (installed in 2002)?

Sure sounds like they have changed the radio frequency. That is the only reason they all would not work.

sflacke, that is the problem. The receiver will accept and work with either technology but not both at the same time. One of the remotes is the rolling code technology and the other is the billion code technology. The problem you have is not uncommon.

Don,
Thanks for your prompt response. What I will try to do is see if I can program the original remote two times without first clearing the codes. If this works, and it sounds like it should, then I will buy the exact remote required for this GDO. I'll let you know how it works.

My previous tenant lost one of the remotes and I need to get a new one. But according to the discussion here, I won't be able to reset two of them, an original and a new one, together. Am I just doomed to have only one remote unless I replace the entire device? I would appreciate your advice.

No just be sure to take the model number off the motor unit. It looks like 139.XXXXXSRTX. If the model number is still on the remote I would take that also. You will need to program the new remote when you get it. I would not buy off e-bay.

I had the car control set to open a different opener. The opener failed and I replaced it. Do I need to clear the old code before reprogramming it? Thanks, again, Eddie

Hi Gail -

My 139.18874 opener has the same remote.

I found a manual on-line (aaaremotes.com) for a liftmaster 1300 that is virtually identical, and am using it to install my second-hand opener. Everything is bang-on so far, and I'm ready to programm the remote. Waiting for batteries to complete the setup.

Sears will provide manuals, quoted me $17 Cdn with 3 weeks delivery.
