Make sure the battery in the keypad is good. If you cannot get the keypad to work using this method to program then your keypad has failed.

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.

SOURCE: garage door opener key pad not working

so i spent the better part of this morning trying to figure this same thing out... here's what I found.

You need to identify the serial number, which is found on the unit hanging from the ceiling... it will be like a 13953970. I found mine behind the lamp light protector thing. NOT the back with the stickers. 41A5021 is actually not the number that is important.

then go to www.managemyhome.com its a website ran by sears. you have to register, for free. then go look for manuals, in one of the tabs running across the top of the site is a choice for manuals. then search by Craftsman then enter the serial number.

then pull up the owners manual and check out the instructions.

** i found out that the old house i bought did not actually have the same keypad opener as came with the craftsman. so i had to closely inspect all sides of the internal keypad opener (not the one outside) and find another serial number. then i went and got the manual from www.managemyhome.com and realized i needed to add a new 9-V battery before I could proceed. So now i'm heading out to walmart to get that.

after a frusterating morning of service number and internet searches I hope after I get this damned battery the clouds will part and god will shine some luck on me.

goodluck to yourself!

On the back panel of the opener itself is a small pushbutton. Press the button and the indicator near it will light. While the indicator is lit, enter the new 4-digit code on your keypad and it will be set. (You are actually programming the receiver with the new code this way. The wireless keypad doesn't store a code.) The programming light goes off on its own.

Tried to reprogram security code for outdoor key pad on 1/2hp craftsman garage door opener according to instructions online, pressed learn button- put in new 4 digit code-held enter. Lights did not flash...


Seems you've done everything right. Press and immediately release the smart/learn button and then walk over and key in a 4 digit code and press enter. If you are sure the battery in the keypad is good then I think your keypad is on the fritz or the wrong one for that opener.

It sounds like your keypad has just failed. Try programming it like this if you haven't.

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 can't get my key pad for my garage door to open. can i reset my key pad to open my garage door???


You can reset the code but it sounds like it may have just failed. Make sure the battery is good and try more than one just in case. To reset the code:

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 your keypad and key in your 4 digit code and press enter.

Can't get it to open from the pad. I went to put in the code and it started flashing so I pressed the star button. after that, the code wouldn't work.


Try programming it again and see if that helps. Press and immediately release the smart/learn button and then walk over to your keypad and key in your 4 digit code and press enter.

For most openers you don't need the old code.

Just press the program button on the powerhead enter the code you want in the keypad and press enter (within 20 seconds).

Craftsman garage door keypad


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.
