Problem Programming more than one remote for craftsman garage door opener
 

I have two remotes and one key pad. They all worked fine until
yesterday, when one of the remotes stopped functioning. I followed the
steps to reprogram and it did not work. I then cleared the memory and
have not been able to get all three to work at the same time. I can
get any of the three to work individually, but not together.

Am I missing something? Is there something I need to do to change
receivers (or whatever it is that processes the signal). I followed
the instructions in the book to no avail...

Help please....
