<HTML>I have been called out to= service many sticking "keys," as the customer said, and found that in proba= bly 50% of the occurrences, it was not the key at all, but negative lost-mot= ion(hammer butts sitting on jacks) that caused the problem, particularly in = newer pianos.  Make sure you check to see that all of the jacks can get= back into place before you squeeze keys!
