MacBook Keyboard Not Working? Fixes When Some Keys Stop Typing

Is it software or the keys?

Find out which side the fault is on first. A setting toggled on by accident or a key-remapping app costs nothing to fix. Debris, a spill or a swollen battery needs the case opened.

A software fault usually hits everything at once or behaves oddly: the whole keyboard goes dead, keys type the wrong characters, quick taps get ignored, or a set of keys moves the pointer. It often clears on a restart and an external keyboard usually misbehaves the same way.

A hardware fault is local and permanent. One key or one row stops while the rest work, a key feels mushy or stuck, or the keyboard quit right after a spill. A reboot doesn't bring it back.

The fixes, in order

Work down the list and stop when the keys come back.

1. Restart and look for a stuck key. Save your work and restart. A frozen process can lock the whole keyboard, and a restart clears it. Then run a finger across the keys and feel for one sitting lower than the rest or not springing back. A key held down by debris can stop the keys around it from registering.
2. Check Mouse Keys, Slow Keys and Sticky Keys. Open System Settings, Accessibility. Under Pointer Control, turn off Mouse Keys: when it is on, keys such as 7, 8, 9, U, I, O, J, K, L and M move the pointer instead of typing. Under Keyboard, turn off Slow Keys (it ignores quick taps) and Sticky Keys (it holds modifier keys).
3. Check function keys, input source and remapping apps. In System Settings, Keyboard, check whether F1, F2 and so on are set to act as standard function keys, which makes the volume and brightness keys need Fn. Check the input source is the layout printed on your keys, and quit any key-remapping app before testing again.
4. Boot into Safe Mode. 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, restart and hold Shift until the login window. Safe Mode loads without third-party extensions, so if the keyboard types here, software is the cause.
5. Reset SMC and NVRAM on Intel Macs. On an Intel MacBook, reset the SMC using Apple's steps for your model, then reset NVRAM by holding Option-Command-P-R for about 20 seconds at startup. Apple silicon Macs have no SMC reset and check NVRAM themselves, so a full shutdown and restart does the same job.
6. Test a USB or Bluetooth keyboard. Plug in any USB keyboard or pair a Bluetooth one. If the external keyboard types perfectly while the built-in one doesn't, the fault is the internal keyboard or its cable, not macOS. That single test tells you whether you need a settings fix or a hardware repair.

Step 6 settles it. If the external keyboard works, macOS and the logic board are fine and the fault is in the built-in keyboard or its cable, which is a contained repair. If the external keyboard also misbehaves, go back to software: a macOS update or reinstall, not a keyboard swap.

MacBook keyboard: some keys not working? Read the pattern

Which keys have died is the best clue we get on the bench. Match your symptom:

• 7, 8, 9, U, I, O, J, K, L, M don't type: almost always Mouse Keys. Turn it off in Accessibility > Pointer Control. If the Option key is pressed five times with the shortcut enabled, it can switch itself back on.
• One letter not working: debris under that key or a worn key mechanism. On a butterfly keyboard (2016 to 2019 MacBook Pro, 2018 to 2019 MacBook Air) a single crumb is enough.
• A row or block of keys dead: usually liquid that reached the keyboard circuit, or a damaged cable. This rarely fixes itself.
• Numbers not working on the MacBook keyboard: Mouse Keys first (it takes over 7, 8 and 9), then liquid, which often runs down the top row.
• Volume or brightness keys not working: check System Settings > Keyboard > Keyboard Shortcuts > Function Keys. If F1, F2 are set as standard function keys, you need to hold Fn.
• Keys typing twice or repeating: a classic butterfly keyboard fault. Cleaning helps for a while; the lasting fix is a replacement.
• Wrong characters appear: the input source is set to another layout, common on Arabic and English keyboards. Check the input menu in the menu bar.

MacBook keyboard light not working

First check it isn't a model without one: MacBook Neo has no keyboard backlight at all, so that is a design limit, not a fault. On other models:

• Raise it from Control Centre > Keyboard Brightness, or with F5 and F6 on older Intel models.
• In System Settings > Keyboard, turn off automatic brightness in low light and check the setting that turns the backlight off after a few seconds of inactivity.
• In a bright room the ambient light sensor may keep it off. Test in the dark.
• On Intel Macs, an SMC reset (step 5 above) restores a backlight stuck off.

If the light still won't come on, or only part of the keyboard lights up, the backlight layer or its cable is damaged, often after a spill. That is a MacBook keyboard repair job.

MacBook keyboard and trackpad not working together

When both fail at once, look for something they share. If an external keyboard and mouse also freeze, macOS has hung: hold the power button to force a restart. If only the built-in ones are dead, the usual causes are liquid that reached the top-case connectors, or a swollen battery pushing up from underneath. Signs of swelling: the trackpad clicks on its own or feels stiff, the case no longer sits flat, or the keys feel raised. Stop using and charging the Mac if you see those, because a swollen battery is a safety risk. See swollen MacBook battery repair and MacBook trackpad repair.

Water or juice on the MacBook keyboard: the first hour

What you do in the first few minutes decides most spill repairs. Water is kinder than coffee, juice or soft drinks, which leave sugar and acid behind that keep corroding after the liquid dries. That is why spilled juice leads to sticky keys days later.

1. Shut it down immediately and unplug the charger. Don't keep typing to see if it works.
2. Disconnect every accessory, then open the lid wide and stand the MacBook upside down in a tent shape so liquid drains away from the board.
3. Blot the keys with a lint-free cloth. Don't use a hair dryer, and don't bury it in rice.
4. Don't switch it on or charge it to test it. Power running through wet circuits is what causes most of the damage.

How to clean a MacBook keyboard after a spill: with the Mac off, wipe the keycaps with a cloth lightly dampened with water or 70% isopropyl alcohol, never dripping. For debris, Apple advises holding the Mac at a 75-degree angle and using compressed air in short bursts across the keys. That is as far as you should go at home. Liquid under the keys needs the board out and cleaned; our MacBook water damage repair page explains how that works.

When it's hardware: butterfly keys, spills and batteries

Butterfly keyboards. The 2016 to 2019 MacBook Pro, the 2018 to 2019 MacBook Air and the 12-inch MacBook used Apple's butterfly design, where a crumb or grain of sand under a key stops it working. Apple's free keyboard service programme covered each Mac for four years after first sale, so it has run out for these models. A careful clean sometimes revives a key; often the mechanism is damaged and the keyboard needs replacing.

Magic Keyboard models (2020 onwards). These scissor-switch keyboards are far more reliable. Most faults we see on them come from liquid or a knock to one key, and a single key mechanism can often be replaced.

Apple vs an independent repair. Apple replaces the whole top case, which includes the battery on many models; an independent workshop can often replace just the keyboard or a single key. For the MacBook Air specifically, see our MacBook Air keyboard guide.
