Bottom Row of Keyboard Not Responding

Ok - so this one is weird and starts with the most dreaded event ever. I splashed coffee on my usb external keyboard. The top of my macbook pro got some on it, but it was closed and didn't get any on the laptop itself. After getting everything cleaned up, the bottom row of keys on that keyboard (Z,X,C,V,B,N,M, ,) do not work. Furthermore, plugging in a different usb keyboard, I got the same result. These keys are working on my internal keyboard. I rebooted - same result.

When I hook an old bluetooth keyboard we were using with a smart tv setup, everything works appropriately.

Any thoughts?
