Try software fixes before replacing an unresponsive MacBook keyboard

A MacBook keyboard that stops responding may not need immediate repair: software glitches or debris can cause problems that users can sometimes resolve themselves. Restarting the Mac and checking the keyboard’s connection or battery are simple first steps.

If those checks fail, the article recommends reviewing Accessibility settings for Sticky Keys or Slow Keys, testing with an external keyboard and starting in Safe Mode to check for app conflicts. For a few faulty keys, it suggests using compressed air with the MacBook tilted, but warns against removing keycaps. Apple Support can assess whether a replacement is needed; 2015–2019 MacBooks were particularly known for issues with their butterfly keyboards.
