I just finished putting mine together, soldering on all the keys and LEDS. I tested each key and all but one worked. Looking closely, it looks like one of the components next to that switch is messed up. See that component to the right of the switch post, just under D35? It is skewed to the right. None of the others look like that.

What kind of component is that? Is it something I can replace myself? Or does it just need to be secured better? I hate the idea of getting a brand new PCB after just finishing all that soldering, but also hate the idea of having a broken brand new keyboard.

That is a diode. You could try re-soldering it (just like the original Ergodox) to see if you get a better connection. I don't know the specific parameters for it, but if the diode itself is busted, replacing it is pretty easy. I'm sure somebody here knows what kind of diode you need to get.

Thanks, I just figured that out. I didn't have the original ErgoDox, but I remembered reading that you had to assemble everything yourself, so figured that was part of it. https://keyboard-configurator.massdrop.com/ext/ergodox/assembly.php#step-2
According to that, its a 1N4148W-7-F. The photo on digikey looks right http://www.digikey.com/product-detail/en/1N4148W-7-F/1N4148W-FDICT-ND/815280

That diode is just misplaced. I would try adding a little extra solder to complete the connection at the top of the photo you posted first. If that fails, pull it, clear the solder, and put the same one back on. If that doesn't work replace the diode.
I say this because it's unlikely the part is defective, why wait and order a new one when you can get to typing right now?
