Unresponsive Keyboard and Trackpad in Macbook Pro High Sierra 10.13.5
I'm not sure what model MacBook you have, but Apple just recently issued a "Keyboard Service Program for MacBook and MacBook Pro." Check out this link (https://www.apple.com/support/keyboard-service-program-for-macbook-and-macbook-pro) to see if your model is eligible. Hope this helps :)
