I have also introduced the tip of an extremely fine knife, between the side of the white key and its mount, here again alternatively on the upper side and the lower side of the key. I am pleased to report that the defective keys on my two NP-25 work now as expected.
Maybe this can solve some NP-41 key problems.

Actually after wiggling around the "9" key inside its shell seems to have improved its responsiveness quite a bit.
Thank you, Jean-Charles!
