If your MacBook keyboard suddenly stopped working, there are a few fixes to try before taking it in for a repair.
Few tech problems can disrupt a workday faster than when your MacBook keyboard suddenly stops working. It could be a single stuck key, or your entire keyboard might stop responding. While the most common reaction is assuming you have a hardware problem and looking for repair options, sometimes the issue can be much easier to fix.
Software glitches or small particles of dirt under the keys can also cause your keyboard to malfunction, so it's worth double-checking what's causing the problem before you panic. We'll walk through a few fixes you can try if your keyboard isn't working properly to see if any of them will fix the problem without needing a physical repair.
Before tinkering with your keyboard, try the simplest potential fix first: reboot your Mac by clicking the Apple menu and then selecting Restart. If you have a wired keyboard, unplug it and reconnect, making sure it has a good connection.
If you're using a wireless keyboard, turn it off and back on. If that doesn't fix the problem, open System Settings > Bluetooth and unpair your keyboard, then pair it again, as that may solve temporary problems. With wireless keyboards, low battery power can cause the keys to stop working. Plug your keyboard into the charger if it has a rechargeable battery, or put new batteries in if they're replaceable.
If those basic checks didn't help, there are a few macOS settings you can change.
