Steps

Goal: Rule out external vs built-in keyboard, then isolate software or hardware cause.

  • Connect an external USB or Bluetooth keyboard. If it works, the built-in keyboard is the issue.
  • Good: External works. Proceed to Built-in checks.
  • Bad: External does not work. Proceed to Software checks.

Check external

Goal: Isolate built-in vs system-wide issue.

  • Connect a USB keyboard or pair a Bluetooth keyboard. Test typing.
  • If the external works, the built-in keyboard or its connection has failed. Turn off Slow Keys and Sticky Keys, restart.
  • Good: External works—focus on built-in keyboard fixes.
  • Bad: External does not work—check Bluetooth and accessibility settings.

Built-in checks

Goal: Fix built-in keyboard when external works.

  • Turn off Slow Keys and Sticky Keys in Accessibility. Restart. Reset NVRAM on Intel Macs.
  • If the built-in still does not work, physical damage or connection failure may need a technician.
  • Good: Built-in works after settings and restart.
  • Bad: Call Apple or a technician.

Software checks

Goal: Fix keyboard when no keyboard works.

  • Turn off Slow Keys and Sticky Keys. Re-pair Bluetooth keyboard if external. Restart.
  • If a USB keyboard works but Bluetooth does not, the Bluetooth pairing or keyboard battery may be the issue.
  • Good: Keyboard works after settings and re-pair.
  • Bad: Try USB keyboard or call a pro.

When to get help

Call Apple or a technician if:

  • An external keyboard works but the built-in one does not after settings and restart.
  • Physical damage or liquid spill.
  • Keys register wrong characters.

Verification

  • Keys register correctly when typing.
  • No delay or missed keystrokes.
  • Slow Keys and Sticky Keys are off if you do not use them.

  1. External keyboard test Connect USB or Bluetooth keyboard; if it works, built-in keyboard is the issue.
  2. Accessibility settings Turn off Slow Keys and Sticky Keys.
  3. Bluetooth and restart Re-pair Bluetooth keyboard; restart the Mac.
  4. Physical check Inspect for stuck keys, debris; blow compressed air under keys.
  5. Call a pro External works but built-in does not; physical damage or liquid spill.
