00165 - Trackpad works Keyboard doesn't

[BrickBreaker]

I have a riddle for you: the trackpad works everywhere (efi and os) and the keyboard works nowhere. The power button works and SMC reset even works but not boot options, not nvram, and none of the keys except power work. No liquid damage, tried new keyboard. I'm stumped.

Measure all pins from 1 to 20 on powered on macbook (lid has to be opened, keyboard has to be connected).

PS. Power on (pin 20) and SMC reset (pin 18) goes on separate lines then rest of the keyboard. Also check corrosion on Trackpad and try another tpad - logicboard ribbon.
