Can not reprogram key pad on my liftmaster garage door opener ,tried every thing in the book ,hand held works and also i am able to open and close from the multi function door control.


If you are sure the battery is good and this doesn't work then you need to replace the keypad.

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

I have a 1/2 hp craftsman opener. Remotes work fine. Wired wall unit has a blinking light on the open button and will not work Lock pad and light pad work but not the operate pad.????


Try pressing and holding the lock button for 3 seconds to stop the light from blinking. Your wall control may be bad. Usually when that light is blinking it is the remotes that will not work.

Key pad not working. Garage door will open with


I'm confused about the battery you replaced inside the garage but you can try programming the keypad just to see.

Locate the smart/learn button on the back of the motor unit near where all those white wires go. Press and immediately release it and then walk over and key in your 4 digit code and press enter. If this doesn't work and you know the battery inside the keypad is good, you have a bad keypad.

My keypad works,my remote opener does not, even


It is related. One of the buttons on your wall control is the lock button and has a lock icon on it. Press and hold it for 3 seconds. The blinking should stop and your remote should now work.

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!
