my work computer is in the shop now as this happened to me this week. they're replacing the whole bottom case, including the expanded battery that has 30 seconds of life left and won't let the laptop sit flat. if anyone has a MacBook 2016-2019 with the crap keyboard, it is under recall for four years after purchase date, so mine was free to repair. just say your keyboard is broken at the apple store and the whole bottom half will get replaced, including little rubber blockers under all the keys. good luck
