It may be easier to replace the whole calc, at least as long it's not an HP-42S, 32SII, or 27S .
And even on those rarer and more expensive Pioneers the problem stays the same: Broken polymer chains. You may have to dismantle the whole calc, which involves various one time plastic connections (stakes) only to get access to the keyboard matrix from behind. IMHO not worth the effort in most cases.
