Finally tore down my 12x5 ortho keyboard and figured out why the 'a' key was not cooperating. For some reason, there seemed to be some debris around that key's solder joints. As counterintuitive as this sounds for a circuit board, I wiggled it ever so slightly, cleaned out whatever dust was there, and now it's back making contact - yay!
Now I get to re-train my muscle memory *back* to this keyboard from my 12x4 layout, which is missing a whole number row. Even the arrow keys have a different layout, so that's gonna be fun.
