keys not returning

Sure sounds like an angled upper section key with a worn center bushing 
to me.  Have you tried using a flat-ended needle file to smooth out the 
sides of the socket that is worn into the felt?  Of course, if you had a 
small chisel, you could pop out the bad felt and put new one in there 
and charge it to misc. repairs.  What'cha think?
