Troubleshooting a MacBook Keyboard Not Working

Your Mac keyboard might stop working due to dust and other contaminants. Additionally, if you own a newer MacBook that features Apple’s butterfly keyboard, even the smallest amount of contamination such as food, dust, or liquid can cause problems to it. In fact, these keyboards were such a problem that Apple even issued a Keyboard Service Program for MacBook, MacBook Pro, and MacBook Air.

So, if your Mac keyboard has stopped working, you can try to fix it with some of the solutions mentioned below. However, you shouldn’t try any advanced repairs or disassemble the keyboard yourself as Apple fixes the majority of these problems for free.

Clean Your Keyboard

Dust and debris are the most common reason for the malfunctioning of Mac keyboards. So, you should start by cleaning the keyboard to the best of your ability.

Put Your MacBook on Charge

Sometimes, if your MacBook’s battery is low, the keyboard might stop working. In this case, you should try plugging in your laptop and let it charge for a while. You can see if the keyboard is working once the Mac is a bit charged.

Turn Off Mouse Keys

If you’ve accidentally turned on the Mouse Keys, the number pad on your keyboard might stop working. So, make sure that the keys are turned off by going to the Mouse tab in System Preferences.

Turn Off Slow Keys

If Slow Keys are turned on, you’ll have to press each key longer than you normally do before the system registers them. This can give the impression of the keyboard not working at all if you press each key for only a short period. Here’s how you can turn the Slow Keys off:

  • Go to the Apple menu and open System Preferences.
  • Click the Accessibility tab and navigate to Keyboard and then Hardware.
  • Turn off the Slow Keys.
