Jokeyman123, thanks for the response. I appreciate a sense of humor. I did take the case apart. 31 screws is all it takes. The key itself seems to be just like new. But the contact pad under it was partially collapsed. That is going to have to be replaced. I don't know if there is supposed to be a return spring inside that rubber pad. But I somehow doubt it. It looks easy enough to replace. But I have had NO luck finding anybody that can give me a drawing with part numbers or even tell me where to buy parts. You can see the part in my photo. (sorry about the auto focus issue) Anyway, only that pad has partially failed.The rest of the keys feel like new. If the keys were 3/8 inch longer, it would be an instrument rivaling some of the best electronic keyboards I have ever played. Excepting hammer action stuff of course.
