Sorry to say that those keypads are not repairable. You could try and reshape the button dome and then try little bits of glue near the area, but you would end up with shorted and open keys instead of just open. There is just no real way to do it that I've ever heard of. looks like you are just going to bite the bullet and order the panel assembly. Let me know if you have any other questions. Thanks, Sam
I appreciate your detailed description. Unfortunately it enables me to give you a fast undesirable answer. I will be more than happy to answer any other questions about this machine.
