Is there a way to replace the entire keyboard assembly?

I only bought this chromebook about a month ago, but tea (mixed with vinegar and honey) ended up getting spilled on it. I cleaned it all out, and it worked fine, but after a while, the keyboard began to deteriorate. The keys are now breaking off, and the damage is to the assembly itself, not the keys.

I can't find any helpful information on how to replace the keyboard, nor any part listings for it.
