Windows 10: Why is my keyboard not working and how do I fix it?

My surface pro keyboard is not working. I’ve tried pressing the Caps and Fn buttons and they won’t turn on.

Built in keyboard not working

I recently purchased an ASUS ROG GL553VD Notebook Computer and a few weeks ago the keyboard stopped working. After a few restarts it worked again, but today the problem came back, and was not fixed by any amount of restarting. Several people on past posts said to reinstall they Keyboard driver, but there was no Keyboard section in the Device Manager. I am currently resetting the laptop to factory settings to see if that fixes the issue. Any other suggestions would be greatly appreciated.
