The "l" and "." keys on the keyboard of my Mac LC630 have stopped
working.  I've taken the cover of the keyboard off and huffed and puffed
in such gaps as there are without prising the keys off, but no change.

With these two characters failing, is this likely to be a mechanical
problem (ie if I dismantle it enough will I probably find a hair or
something in the works), or is it more likely to be something electronic
(ie new keyboard)?

I'd be really grateful for any tips ...
