This is such a MISS by Microsoft. I have the same issue.
So a >$1,000 computer works fine and has a ton of processing power and memory, but because keys stop working, we have to replace the entire unit? And the best Microsoft can offer out of warranty is as much as many new laptops?
I had a Surface, Surface Pro 3 and now Surface Book 3. Guess I will be purchasing a Macbook instead.
Create an aftermarket keyboard at least.
