Wireless keypad won't accept our original code. Door won't open. When I enter the code the backlight on the keypad blinks rapidly. I need help. I have no other way to get in my garage. Thanks, Ryan

If you are talking about a keypad try this.
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.
If that doesn't work you have a bad keypad.

Make sure you are doing it like this.

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.

The keypad lights should blink after the enter button is pressed. It is not necessary to hold the enter button. Sounds like a bad keypad.

Try programming the keypad by doing this:

Press and immediately release the smart/learn button and then walk over to your keypad and key in any 4 digit code you like and press enter. If this doesn't work you keypad has quit.

Your keypad needs to be replaced.

Push the learn button on back of opener. Set new code, hit enter. Light will blink twice when accepted.

Sounds like the new keypad is simply not compatable with your opener. Contact the sears store and speak with the sales person trained on garage door openers. You may find that you simply do not have the wireless key pad you need. good luck

It sounds like this remote has lost its program! you will have to reprogram it!I hope this helps ya!

Hello,Linda well this is your lucky day ,I have installed garage door openers for sears for 10 years and i can tell you that craftsman,chamberlain ,and liftmaster are all the same machine and manufactured under the liftmaster name , if you buy it from home depot it will be a chamberlain ,if you buy it at sears ,it will be a craftsman, and if you go to commercial building supplier it will be a liftmaster! now getting that out of the way even though they are all compatible ,there is one thing that stands in their way and that,s time ,For example if your chamberlain machine is 5 years old and you went to sears last week ,the chances of the frequency being the same are not good , most likely you have the wireless keypad , one way to test the sears keypad against the chamberlain machine is to locate the smart button on your machine ,this button allows for programming of remotes and keypads , to test and see exactly what im talking about take your remote and locate the smart button ,if you have three buttons on the remote press one of the buttons that are not being used on the remote ,above the smart button their will be a blinking light ,if you press your remote button you will notice the light go from a blink to a rapid flash , This is telling you that you are sending a signal for programming to the machine , well the keypad is exactly the same all you have to do is push the enter button on the keypad and have someone watch for the rapid blinking light ,if they are compatible the light will blink rapidly on the machine so all you have to do now is have someone press the smart button once on the machine your indicator light will now be a solid light you will have approx 60 seconds then to put a 4 digit code in the keypad and then press and hold down the enter button on the keypad , at this point you will notice the lightbulbs on the chamberlain machine to shut off and come back on this is to tell you that the machine accepted the code , after thats been done you can use your keypad , you can also find the owners manual to the chamberlain and follow the same instructions to programming the remote , they are identical in programing , if your keypad is not the same frequency you can also tell by looking at the frequency code on the backside of the keypad and also the chamberlain unit usually where the light bulb is will be its code

The blinking on your keypad simply means that a code of some sort was sent. Whether it be the right on or not. Lets try to reprogram the unit. Press the colored learn button on the motor head and then within 30 seconds enter in the 4 digit code followed by the up/down action button. The light bulb should flash to let you know it has been accepted. Wait 5 minutes and try. If it does not work replace the keypad.
