I've been doing that for awhile now, it no longer works.

It would be nice to know what causes the PCB-keyboard connection to fail like this. Is it dust getting into the pads and interfering with the connections? AFAICT the pads are gold so corrosion shouldn't be an issue. Does anybody know?

If there were a definite answer I could decide if I wanted to try untwisting the tabs, to remove the PCB and clean out any dust. But that sounds risky and I don't want to do it unless there's a good chance it will fix the problem.
