Can not get wireless keypad and remote programmed together...

I have hcb1127 and I can not get both programmed together. I can get the keypad to work when I reset the codes. I can get the remote to work when I reset the codes. But I can not get both to program at the same time. Any suggestions!

    My keypad does not work at all. When I reset the remote transmitters one at a time, which ever one I set works fine, but the other one will not work. I can not reset them both at the same time so only one will work. What could the problem be?

Can you program more than one remote for a liftmaster model 1160 garage door opener? When I try, one works but the other doesnt. Seems to knock the other remote out.


When this happens it is usually because you are trying to program two remotes that are not compatible. Even though they will both work they will not work together. Take the model number off the one that works best and get an exact replacement.

The garage door remotes I have, aren't working properly when one remote is programmed it disables the other, and also the outside keypad isn't working either.


One of your remotes has reverted to an earlier technology and although they will each work individually they will not work together. You need to purchase a new remote of the same model number you have and you will find that the new remote will work with one of your remotes but not the other. Remove the battery from the bad remote and discard it to prevent problems down the road.

Have two remotes,only can get one to work youcan program one and the other you cant program


One of your remotes has reverted to an earlier technology. You will need to purchase a new remote and by a process of elimination find which two work together. Remove the battery from the other remote and trash it.

Trouble programming both the keypad and the remote controller


One of them has either reverted to an earlier technology or you have the wrong one for your opener. If one or both of them are new, one or both of them are the wrong one. If they are originals then my first sentence is correct. The problem is finding out which is the bad one. Most commonly it is the hand remote but there is a 50/50 chance.

Can only program one remote or keypad. which ever


You are going to have to do a process of elimination. I think you have either a bad remote or a bad keypad. Try programming a remote and then the keypad. If only one works then go with the other remote and the keypad. If only one works then program the two remotes. If the two remotes work then the keypad is bad or if you can program one remote and the keypad then the other remote is bad. Get rid of the bad one.

Sears garage door keypad/remote programming problem


Hi All,

I had the same issue recently and here's what I found out (through a LOT of research) and the solution (yes, there is one!):

As described by many, when you can't get both the remote and the wireless pad to work together it means your garage door opener can accept both rolling code and billing code technology, BUT not at the same time. When you reset all codes (normally by pressing a button on the opener for a period of time e.g. 6 seconds or more), you erase all codes and remote "pairings". Then when you follow the manufacturer's procedure to pair again (which could be the wireless key pad first OR the remote first), the first pairing determines the technology for all subsequent pairings. Example: if your first pairing/programming was with the wireless keypad, and if it was rolling code technology (normally the case for newer models), then the garage opener will only recognize and accept rolling code for subsequent pairings. If your remote(s) are older (billion code technology) then the opener won't even recognize the signal (e.g. led won't blink when trying to pair/program).

And vice versa if you start with your remote after erasing all programming (then your keyless pad won't work).

But here is a potential workaround! For newer wireless keypads (e.g. clicker from chamberlain), you have an option to select the type of opener you are using as you do the initial password set up (normally indicated by a number e.g. 1 for models built after 1995, 2 for models built between 1997 and 2004, etc). Each choice is associated with a technology in the background (e.g. either rolling code or billion code). If you are programming your wireless keypad first after erasing all codes / programming, if you chose the "recommended" option for garage opener, chances are it will be rolling code and that means you won't be able to program your older remotes (billion code) after that. So how can you chose the option that will match your remote???

Here's what you do: start by pairing / programming your older remote first after erasing all codes / programs. That sets the technology (e.g. billion code). Then, go ahead and program your wireless keypad, but you may have to go through the process several times by trying the different options until you find one that works!

For me, I had to try 4 options before making it work. Options 1 through 3 (mind you, options #2 was the exact match for my garage door opener model but it would cause the problem discussed here e.g. wireless keypad would work but not the remotes) would not even be recognized by the opener in this procedure (LED would not blink), but it did work once I hit option 4.

I hope this will help you with your problem. Let me know if it's not clear. Cheers!
