MacBook Pro keyboard

[JEF2311]

MacBook Pro 13" (2015) needed new battery. To drain existing battery I let MacBook on, but also update OS X to Big Sur. Replaced battery and charged it. Upon boot, all worked but not keyboard. Trackpad works but keyboard doesn't. Replaced track pad cable, but keyboard is still nil. Any suggestions? Many thanks!

Hi,

I know this is a long shot, but Apple recommends a good clean for unresponsive keyboards.

1. Hold your MacBook at a 75-degree angle.
2. Use compressed air to spray the keyboard in a left-to-right motion.
3. Rotate your MacBook onto to its right side and spray the keyboard again, from left-to-right.
4. Repeat with the MacBook rotated to its left side.
