Assuming, from what I read, the remote works..The inside switch is just a doorbell switch which will wear out or have the contacts get bent or dirty. Take off wall, and change for new one or see if the contacts can be cleaned or adjusted. If the pad is electronic (coded) the wires may be bad or the control defective. Usually momentary contact of the two wires will cause the door to actuate.

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!

Yes, this is a common problem. I recommend the Domino GD-1. It is a wired keypad but the batteries are on the inside so they stay warm, plus you can use from 1 - 6 digits instead of just 4. It is harder to install but worth the effort.
It does not come with wire so you will have to get some bell wire.

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.
