Ex-Arsian Casey Johnston is upset because her 2016 MacBook Pro's space bar stopped working. (It also sounds like she doesn't much like the butterfly key action to begin with.) The keys are difficult to remove without breaking and top case replacement is usually required to fix keyboard issues. She quotes a Genius who speculates that dust is stuck in the space bar and says the issues are very common. I have a 2016 MBP too and really like the keyboard action, but don't particularly like the idea of frequent and expensive-to-fix failure. Have you experienced failure of a butterfly keyboard on a 2015+ MacBook or 2016+ MBP? If so, was top case replacement necessary, and did Apple give you any trouble over it.

Please help

I didn't find the right solution from the internet.
