Chosen Solution
I have spilled something onto my keyboard. I have used some kind of dust spray on it, the MacBook works besides some keys that don’t respond. Is it possible to replace the entire keyboard? And how?
At this time the only means to replace the keyboard is to replace the assembly it is part of. Review this IFIXIT guide: Retina MacBook 2015 Upper Case Assembly Replacement. As you can see its a bit of work as you’ll need to take the entire system apart. Here is the part you’ll need: MacBook 12" Retina (Early 2015) Upper Case with Keyboard - Used that IFIXIT store has available.
You can replace the keyboard only, not uppercase. Just has tiny screws.
