HP-25 sealed keyboard with non responding key

[John Garza (3665)]

There is, of course, the direct approach.

Slice off the tops of the heat stakes and disassemble the keyboard.
Clean normally as you have full access.
Reassemble and use melted plastic to rebuild the tops of the heat stakes.

And while you're in there, it's a good time to clean/lube the slide switches.
