Try this Les

DEOXIT gold introduced through the pinhole associated with the switch. Hopefully you have the keyboard design with the pinholes. If it were mine and it did not have the pinholes I might consider drilling a tiny hole BY HAND (tiny drill bit between thumb and forefinger or held in a pin vice) over the centre point of the offending button and introduce the DEOXIT that way.

Still no joy, then the extreme, remove the tops of the heat stakes, minimal amount leaving enough in place to remelt after cleaning the board. The last method is the most extreme and difficult so try drilling the tiny hole first.
