Welp - I think I messed mine up. Broke off one of the diodes while I was loading it into the case and a whole row of keys don't work at all. They worked when I initially tested them, but then didn't after putting it all together so I went back to investigate and that's when I noticed the broken diode.
I tried replacing the diode but didn't have any luck. Does anyone know these pcb's well enough to guide me through checking some things or possible fixes?

Did you check the polarity of the diode? If the diode is broken you could (temporarily) try an LED instead, they are diodes too. If that fixes things it should be fairly easy to procure a new diode. Without the diodes entire rows or columns will fail.

OMG, that makes a lot of sense. I wouldn't doubt that I put the diode on the wrong way. Let me try that and report back if it works the other way around.
Here's more info in the meantime: The keys that don't work were on the left hand side. The row from tab/q/w/e/r. (T was fine though). The diode that I broke was the one on the middle bottom key (f1 for the default config). Here's hoping those link up and it was just that one...
I am obviously a bit of an electronics noob. I got pretty okay at the soldering bit though. And I have plenty of spare diodes now to try this with.
Hopefully switching that around does the trick. If not, I'll check back here to see if anyone else has other suggestions.
