I had to replace some some scratched and chipped cassette keys on a JVC M70. They are hard epoxied to the control arm and almost impossible to remove. But here is how I did it.

I got a Soldering Iron with a large tip for good heat transfer.



I placed the soldering iron and applied heat to the control arm for a few minute just enough to soften the hard epoxy, then just pulled the key out from the control arm.


THAT'S IT!!
Here it is complete.
