Your post is somewhat ambiguous

When I did advertising lay-out for a newspaper - we used a stickly wax in the "paste-up."

Not only was it grand for an accordian reed - it was the best wax for your surf-board....in cold waters.

Personally, I now use super-glue.

If - the pressure-pad-key is "sprung" - simply pop the cover - and bend the metal attachment to the correct allignment.
