Everything replaced. Keyboard doesn't work

You know, I've been so dedicated to fix this %#*@ thing. New battery, new logic board, new bottom case with new keyboard (got two because first one was bad). new trackpad, new cables and yet...... the keyboard STILL doesnt work. At this point, with money sunk into this....I guess its just ready to retire. Not sure if anyone has had this experience, but its been pretty frustrating. Everything else works fine otherwise.

Mouse works fine... power button works fine. Just been the keyboard. I've gone through every variable I could think of.. at this point I have no clue what else there.
