How do I replace the keyboard on an XE503c12-k01us Model?

I got a hold of a Samsung Chromebook 2 that has a huge issue with the built in keyboard not working properly. I get strange things like the volume down button bringing up some kind of Menu for something unrelated, the e button acting like a power button, and nearly all the other buttons do nothing. I believe you get the idea at that point. I was hoping for a compete teardown to help in the process of replacing the defective keyboard as the device responds nicely with an external keyboard. As it sits though, nobody has gone that far into the palmrest section of this device. (battery replacement or touchpad) So I'm sort of at a loss on how to move forward from this point.
