MacBook Keyboard Not Working? Here’s How to Fix It

Quick Answer

Test the keyboard with an external keyboard and Keyboard Viewer. Then turn off Slow Keys and Mouse Keys, check your input source, restart and update macOS. If whole rows of keys stay dead, or the problem continues at the login screen, the keyboard needs repair.

Key Takeaways

• Settings cause many “dead keyboard” cases, especially Slow Keys, Sticky Keys and Mouse Keys.
• Three quick tests tell you whether it’s software or hardware.
• Reset steps depend on your Mac: Apple silicon has no SMC reset, while Intel Macs do.
• Rows or columns of dead keys usually mean hardware.
• Spills need immediate action. Power off and don’t wait.

The fixes differ a little by model, so check yours first (Apple menu > About This Mac):

Why Is My MacBook Keyboard Not Working?

A MacBook keyboard usually stops working because of an accessibility setting like Slow Keys, a software glitch, debris or a failed keyboard. Test it with an external keyboard and Keyboard Viewer. Fix settings and restart first. If rows of keys stay dead or the problem continues at the login screen, the keyboard needs repair.

What Are You Seeing?

3 Quick Tests Before You Try Anything Else

1. External keyboard. Connect a USB or Bluetooth keyboard. If it works, the Mac is fine and the built-in keyboard is the issue.

2. Keyboard Viewer. Search Spotlight for “Keyboard Viewer” and press the keys while watching the on-screen diagram. If a key lights up there but doesn’t type, the Mac registers it, so the problem is software. If it doesn’t light up, the key isn’t being registered.

3. Login screen and Recovery. Restart and try typing your password at the login screen, then in Recovery (Apple silicon: hold the power button and choose Options; Intel: hold Command + R). Keys that fail everywhere point to hardware. Keys that work there but not after login point to software or settings.

10 Fixes for a MacBook Keyboard That Isn’t Working

1. Restart your Mac

A normal restart clears many temporary glitches. If you can’t log in because of the keyboard, use an external keyboard or the on-screen keyboard.

2. Turn off Slow Keys, Sticky Keys and Mouse Keys

Go to System Settings > Accessibility > Keyboard and switch off Slow Keys, which makes a working keyboard feel dead, and Sticky Keys. Then open Accessibility > Pointer Control and make sure Mouse Keys is off, since it can stop a number of keys from typing normally.

3. Check your input source and keyboard shortcuts

In System Settings > Keyboard > Text Input > Input Sources, make sure the right layout is selected and remove ones you don’t use. If only function keys misbehave, check Keyboard Shortcuts > Function Keys, and look at Modifier Keys too.

4. Disconnect other keyboards and Bluetooth devices

Turn Bluetooth off briefly and unplug USB keyboards. A paired external keyboard can change how macOS treats the built-in one. If you use a wireless keyboard and it’s the problem, re-pairing it by forgetting the device and adding it again often helps.

5. Quit remapping and utility apps

If you’ve installed key-remapping, text-expansion or keyboard-customising apps, quit them and test. A new app can interfere with typing.

6. Clean the keys carefully

Shut the Mac down. Hold it upright at about a 75° angle and use short bursts of compressed air from left to right, or gently brush the keys. This is a widely used method for clearing debris from under the keys. Avoid shaking the Mac vigorously, prying off keycaps, or using liquids.

7. Update macOS

Go to System Settings > General > Software Update. If it won’t install, read our guide to a MacBook that won’t update macOS.

8. Test in Safe Mode and a new user account

On Apple silicon, shut down, hold the power button until startup options appear, select your disk, hold Shift and click Continue in Safe Mode. On Intel, hold Shift at startup. Then create a test user in System Settings > Users & Groups. If the keyboard works in either, an app, login item or preference is the cause.

9. Reset the SMC and NVRAM (Intel Macs only)

On an Intel Mac, resetting the SMC and NVRAM can clear stubborn glitches. Follow Apple’s steps for your model, since they differ between T2 and older Macs. On Apple silicon (M1, M2, M3 and later), you simply shut down and start the Mac again.

10. Run Apple Diagnostics, then reinstall macOS as a last resort

Run Apple Diagnostics (Apple silicon: hold the power button at startup, then press Command-D; Intel: hold D). If everything checks out and keys still fail, reinstall macOS from Recovery, which keeps your files. Back up first.

How Can You Keep Working Meanwhile?

• Plug in an external keyboard, wired or Bluetooth
• Turn on the Accessibility Keyboard in System Settings > Accessibility > Keyboard
• Use dictation and Keyboard Viewer to click individual keys

What If the Backlight Isn’t Working?

If the keys type but the backlight is off, check System Settings > Keyboard > Keyboard brightness. Low Power Mode and the “turn off backlight when idle” settings can also dim it. If the backlight still won’t come on at any setting, or it flickers, a technician should check the keyboard and its cable.

What Should You Do After a Spill?

1. Power the Mac off immediately (hold the power button) and unplug it.
2. Turn it keys-down over a towel to let liquid drain, and blot the surface.
3. Don’t switch it on to see if it works, and don’t use rice or a hairdryer.
4. Get it inspected promptly. Sweet drinks and salty liquids corrode components quickly.

Keys can fail days after a spill, as residue spreads. See our page on MacBook water damage repair.

Is Your Mac Covered by Apple’s Keyboard Service Program?

Apple ran a Keyboard Service Program for certain MacBook, MacBook Air and MacBook Pro models with butterfly keyboards made from 2015 to 2019. It covered a limited period after the original purchase, so check Apple’s page for your model, because most eligible Macs are now past the window. Apple silicon Macs and newer scissor keyboards aren’t part of it.

When Does the Keyboard Need Repair?

Repair is the answer if:

• Rows or columns of keys are dead
• Keys fail at the login screen and in Recovery
• The external keyboard works but the built-in one doesn’t
• Apple Diagnostics reports a fault
• Keys stay stuck or double-type after careful cleaning
• It began after a spill, drop or pressure on the lid

What Does MacBook Keyboard Repair Involve?

1. Diagnosis: confirming it’s the keyboard, not software or the board
2. A clear finding: which keys or sections are affected, and why
3. A fixed quote: before any work starts
4. Repair: replacing the keyboard or top case assembly, or a keycap if only that is broken
5. Testing: every key, the backlight, Touch ID and the trackpad
6. Handover: with an invoice and warranty

On most MacBooks the keyboard is built into the top case, which also holds the trackpad and battery, so a careful technician checks those during the repair. Your files stay on the SSD, but back up first if you can.

If you’d like a diagnosis, our MacBook keyboard repair in Dubai starts with identifying exactly what’s failing. For model-specific guidance, see our guides for the MacBook Pro M4, MacBook Pro M3 and MacBook Air M2. To compare shops, read how to find reliable MacBook repair services in Dubai.

What Should You Ask a Repair Shop?

1. Is the diagnosis free, and is the quote fixed?
2. Is it a keycap, the keyboard or the whole top case?
3. Which parts do you use, and what warranty comes with them?
4. Will you check the battery and trackpad while it’s open?
5. How long will it take?

Be wary of any shop that quotes a keyboard replacement without testing the Mac.

How Can You Prevent Keyboard Problems?

• Keep drinks away from the Mac
• Never close the lid on earbuds, pens or camera covers
• Wipe the keys with a lint-free cloth, slightly damp at most
• Avoid eating over the keyboard
• Use a padded sleeve, and don’t stack heavy items on the Mac
• Back up regularly, so a repair never feels risky
