Understanding Why Your Keyboard Stops Working
A keyboard that won't respond can happen for several reasons, and knowing what's actually going on helps you fix it faster. Sometimes it's a simple connection issue. Other times it's settings on your computer getting in the way. Your keyboard might be locked by accident, caught in a power-saving mode, or dealing with driver problems—which are the programs that let your computer talk to your keyboard.

The most common culprit is a loose connection. If you're using a wired keyboard, the USB cable might not be seated all the way into your computer's port. If it's wireless, the battery could be dead, or your computer and keyboard lost their connection. These issues account for roughly 40% of keyboard problems that people report. The other 60% splits between software issues, accidental locks, and actual hardware damage.
Another frequent cause is the Num Lock or Caps Lock key getting pressed without you realizing it. Some keyboards have lights that show when these are on, but not all of them. You might type something and see nothing appear on screen, then panic—when really your keyboard is in a mode that's preventing normal input. Similarly, Filter Keys or Sticky Keys (accessibility features built into Windows and Mac) can lock your keyboard into behaving differently than you expect.
Before you assume your keyboard is broken, it helps to understand that software locks and connection issues are far more common than actual hardware failure. This guide walks through testing methods and fixes that work for most people. The key is trying them in order, starting with the easiest ones first.
Quick Checks You Can Do Right Now
Start with the basics before doing anything complicated. These quick checks solve the problem about half the time, and they take just a few minutes.

For wired keyboards: Unplug the USB cable from your computer completely. Wait 10 seconds. Plug it back in firmly—you should feel it click into place. If your keyboard has a separate power switch, make sure it's turned on. Look at the cable itself for any visible damage, pinches, or cuts. If you see damage, the keyboard likely needs replacement, but try a different USB port on your computer first to rule out a faulty port.
For wireless keyboards: Check the battery compartment. Most wireless keyboards use AA or AAA batteries. Open the battery cover and make sure batteries are installed correctly, with the positive and negative ends facing the right direction. If batteries are in there, replace them with fresh ones anyway—low batteries are the single most common cause of wireless keyboard problems. If your keyboard has a power switch, flip it off and back on. Wait about 5 seconds for it to reconnect to your computer.
For both types: Look at your screen. If the cursor is frozen and nothing else works either, your computer itself might be locked up—not just your keyboard. Try pressing Ctrl+Alt+Delete on Windows or Command+Option+Escape on Mac. This opens a menu where you can restart your computer. If your keyboard works for that, great. If not, hold your computer's power button for 10 seconds to force it to shut down, then turn it back on.
Check indicator lights. Most keyboards have small LED lights that show Num Lock, Caps Lock, or battery status. If you're on a laptop, pressing Num Lock might lock the number pad portion of your keyboard. Try pressing Num Lock again to toggle it off. The same goes for Caps Lock—if it's on, all your letters will type as capitals, which might look like nothing's working if you're not expecting it.
Fixing Connection and Driver Problems
When the quick checks don't work, the issue is often a connection dropout or an outdated driver. Drivers are special programs that act as translators between your keyboard and your computer's operating system. Without the right driver, your computer doesn't know how to read signals from your keyboard, even if the keyboard itself is working fine.

Reconnecting a wireless keyboard: Most wireless keyboards have a pairing button on the bottom or back. Press and hold this button for 3-5 seconds until you see the LED blink. Your computer should detect the keyboard within 10 seconds. On Windows, go to Settings > Devices > Bluetooth & other devices and look for your keyboard in the list. If it appears, click it and select "Connect." On Mac, go to System Preferences > Bluetooth and do the same. Sometimes unplugging the wireless receiver (the small USB dongle) and plugging it into a different USB port helps too.
Updating drivers on Windows: Right-click the Start button and select "Device Manager." Look for "Keyboards" in the list and click the arrow next to it to expand that section. You should see your keyboard listed. Right-click on it and select "Update driver." Choose "Search automatically for updated driver software." Windows will check online and install any newer versions. After this finishes, restart your computer. If the keyboard still doesn't work, try right-clicking the keyboard again and selecting "Uninstall device," then restart. Windows will reinstall the driver automatically.
Updating drivers on Mac: Click the Apple menu and select "System Preferences" (or "System Settings" on newer versions). Go to Keyboard > Keyboard. If there's an "Update" button, click it. For wireless keyboards, also check System Preferences > Bluetooth and make sure your keyboard shows as "Connected." If it shows "Not Connected," click it and select "Connect." Unlike Windows, Mac doesn't have a traditional driver manager, but you can check for system updates by going to System Preferences > Software Update, which sometimes includes keyboard-related fixes.
What to do if the driver update doesn't help: Go back to Device Manager on Windows and look for any devices with a yellow triangle or exclamation mark—these indicate problems. If your keyboard shows a warning, right-click it, select "Properties," and note the error code. Search that code online for specific troubleshooting steps. As a last resort, you can uninstall the keyboard driver entirely and let Windows reinstall it fresh when you restart.
Disabling Accidental Keyboard Locks and Accessibility Features
Windows and Mac both have built-in features designed to make keyboards easier to use for people with certain disabilities. These features are helpful when you want them, but sometimes they get turned on accidentally, making your keyboard behave strangely or stop responding entirely. Learning where these settings hide can solve your problem without needing any hardware fixes.

Sticky Keys on Windows: This feature makes it easier to press keyboard combinations like Ctrl+Alt+Delete by letting you press one key at a time instead of all together. When Sticky Keys is on, your keyboard might seem unresponsive or behave oddly. To check if it's enabled, go to Settings > Ease of Access > Keyboard. Look for "Sticky Keys" and make sure the toggle is off. If you see it was on, turn it off and test your keyboard. You can also press the Shift key five times in a row—Windows will ask if you want to turn Sticky Keys on or off. Select "No" if you don't want it.
Filter Keys on Windows: This feature ignores repeated keystrokes that happen when you hold down a key. It can make your keyboard seem slow or unresponsive. In the same Ease of Access menu, find "Filter Keys" and turn it off. Like Sticky Keys, there's a keyboard shortcut: hold the Shift key on the right side of your keyboard for 8 seconds. A dialog box will ask if you want to turn on Filter Keys. Click "No."
Accessibility features on Mac: Go to System Preferences > Accessibility > Keyboard. Look for "Slow Keys" and "Full Keyboard Access." If Slow Keys is enabled, your Mac waits after each keystroke before registering it, making typing feel broken. Turn it off by unchecking the box. Full Keyboard Access lets you navigate using only the keyboard, which can interfere with normal typing in some programs. You can also toggle Full Keyboard Access by pressing Control+F7.
Num Lock on older computers: Some BIOS settings (the very basic system information your computer loads before Windows or Mac starts up) can lock the Num Lock key in a specific state. If you have an older computer and Num Lock won't toggle off no matter what you do, restart your computer and look for a message that says "Press [
