Hold down learn button for 8 seconds. This clears the memory for all remotes. Then reprogam your remotes

It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

Its very possible for someone esle to have your code I would say try two things. The first thing is too check your wall button wire shake it is a little make sure there are not cuts or staples in the wire its self cause it to short out and run. Then change your codes is pretty easy on the back of the opener unit its self there are the dip switchs you will most likly need a step stool. Just move 2 or so of the dip switchs and then move the same ones on your remote. On your remote the dip switchs should be undernether the batter cover

SOURCE: reprogram keypad with new code

Here is a link that will give you the programming instructions for your model.
Use the model number from the motor unit, not the remote. I believe that Craftsman now goes under the Liftmaster name.
