This problem crops up when the bottom of the key is at an angle, or the plunger is not 90 degrees to the bottom of key. As the plunger comes up, the angle becomes more acute, the rubber tip locks in place and won’t slide back to rest position. I’ve applied thin CA glue to bottom of key, sand with 400 grit paper to make bottom of key glossy smooth, then apply judicious amount of lube. <o:p></o:p></span></font></p> <p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size: 10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p> <div> <p class=MsoAutoSig><b><font size=5 color=navy face="Lucida Calligraphy"><span style='font-size:20.0pt;font-family:"Lucida Calligraphy";color:navy;font-weight: bold'>Dean</span></font></b><b><font size=5 color=navy face="CAC Leslie"><span style='font-size:20.0pt;font-family:"CAC Leslie";color:navy;font-weight:bold'><o:p></o:p></span></font></b></p> <p class=MsoAutoSig style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom: 3.0pt;margin-left:0in'><font size=2 color=navy face=AGaramond><span style='font-size:10.0pt;font-family:AGaramond;color:navy'>Dean W May                (812) 235-5272 voice and text <o:p></o:p></span></font></p> <p class=MsoAutoSig style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom: 3.0pt;margin-left:0in'><font size=2 color=navy face=AGaramond><span style='font-size:10.0pt;font-family:AGaramond;color:navy'>PianoRebuilders.com    (888) DEAN-MAY        </span></font><font color=navy><span style='color:navy'><o:p></o:p></span></font></p> <p class=MsoAutoSig style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom: 3.0pt;margin-left:0in'><ST1:PLACE u1:st="on"><u4:CITY u1:st="on"><u2:place u3:st="on"><u2:City u3:st="on"><st1:place w:st="on"><st1:City w:st="on"><font size=2 color=navy face=AGaramond><span style='font-size:10.0pt;font-family:AGaramond;color:navy'>Terre Haute</span></font></st1:City><font size=2 color=navy face=AGaramond><span style='font-size:10.0pt;font-family: AGaramond;color:navy'></u2:place></st1:place></u4:CITY> <U2:STATE u1:st="on"><u2:State u3:st="on"><st1:State w:st="on">IN</u2:State></u2:State></U2:STATE></st1:State> <U2:POSTALCODE u1:st="on"><u2:PostalCode u3:st="on"><st1:PostalCode w:st="on">47802</u2:PostalCode></u2:PostalCode></U2:POSTALCODE></st1:PostalCode></span></font></st1:place><o:p></o:p></p> </div> </ST1:PLACE> <div> <div class=MsoNormal align=center style='text-align:center'><font size=3 face="Times New Roman"><span style='font-size:12.0pt'> <hr size=2 width="100%" align=center tabindex=-1> </span></font></div> <p class=MsoNormal><b><font size=2 face=Tahoma><span style='font-size:10.0pt;
