Keys Not Registering

Keys that don't register when pressed prevent typing and input. This page covers how to fix keys that aren't registering. Start by identifying which keys are affected, then clean and test the keyboard.

You can verify every key using the keyboard test.

Test Which Keys Are Affected

Use an online keyboard test to identify which specific keys aren't registering.

• Open the keyboard test page
• Press each key systematically
• Note which keys don't light up or register
• Check if it's specific keys or a pattern
• This helps determine if it's hardware or software

Clean Keyboard

Debris under keys is a common cause of keys not registering. Clean the keyboard.

• Turn keyboard upside down and shake gently
• Use compressed air to blow out debris
• Clean around affected keys with a soft brush
• Remove stuck keys carefully if needed
• Test keys after cleaning

Check for Physical Damage

Physical damage to key switches can prevent keys from registering. If keys are stuck or repeating, see the guide on sticky or repeating keys for specific solutions.

• Inspect affected keys for visible damage
• Check if key caps are properly seated
• Look for broken or bent key switches
• Test if keys feel different when pressed
• Mechanical keyboards may need switch replacement

Check Keyboard Connection

Loose connections can cause intermittent key registration issues.

• Unplug and reconnect USB keyboards
• Try a different USB port
• Check USB cable for damage
• For wireless keyboards, check battery and reconnect
• Test keyboard after reconnecting

Update Keyboard Drivers

Outdated drivers can cause key registration problems. Update drivers.

• Windows: Device Manager → Keyboards → Right-click keyboard → Update driver
• Restart computer after updating
• Test keys again
