MacBook Keyboard Not Working? Troubleshoot with These Steps

Is your MacBook keyboard not working? Don’t worry, we’ve got you covered. At Salvation Repair, we understand how frustrating it can be when your keyboard stops working. In this tutorial, we’ll walk you through the steps to troubleshoot and potentially fix the issue.

Before we dive into the troubleshooting steps, it’s essential to note that software issues are often the culprit behind a non-functional keyboard. So, let’s start with some software-related solutions.

Software Fault

Incorrectly configured settings, app conflicts, and malware infections can all cause keyboard issues. Let’s address these potential problems one by one.

First, check your keyboard settings to ensure that they’re configured correctly. You can do this by going to System Preferences > Keyboard. If you’re using a third-party app that modifies keyboard behavior, try disabling it to see if it resolves the issue.

Next, restart your MacBook in Safe Mode to isolate the problem. To do this, restart your MacBook and immediately hold down the Shift key. Release the Shift key when you hear the boot chime for the second time. If your keyboard works in Safe Mode, it’s likely a software issue.

Run a virus scan using an anti-malware software like Malwarebytes or Avast to detect and remove any malware that might be causing the issue.

Debris in Keys or “The Butterfly Keyboard Effect”

Dust, lint, and crumbs can accumulate under your keyboard keys, causing issues. This is more likely to affect individual keys than the entire keyboard.

Give your keyboard a good clean by turning your MacBook upside down and gently shaking it. You can also use compressed air to blow out any debris. If you’re comfortable with DIY repairs, you can remove the key caps to clean underneath.

Battery Swelling

Lithium-ion batteries can swell with age or due to underlying issues, causing internal pressure that may affect the keyboard and trackpad.

If you suspect battery swelling, it’s essential to take precautions to avoid any damage. You can try resetting the System Management Controller (SMC) or seeking professional help from a repair service like Salvation Repair.

Faulty Trackpad or Trackpad Cable

The trackpad cable may be at fault, even if you have a dedicated keyboard connection. Keyboard-related components may be on the trackpad itself or connect to a small daughterboard.

If you’re not comfortable with DIY repairs, it’s recommended to seek professional help from a repair service like Salvation Repair.

Faulty Keyboard Cable

The keyboard cable may also be at fault, although this is less common. If you’ve previously repaired your MacBook, it’s possible that the keyboard cable was damaged during the process.

Keyboard Is Faulty

Ultimately, the issue may be with the keyboard itself. This can be due to liquid damage or other factors. MacBook keyboards are often difficult to replace, and it may require replacing the entire top case.

If you’re not comfortable with DIY repairs or if the issue persists after trying the above steps, it’s recommended to seek professional help from a repair service like Salvation Repair.
