Keyboard Tester Pro

Yes, Keyboard Tester Pro is completely free to use. There are no hidden fees, subscriptions, or premium features. Our keyboard testing tool is available 24/7 with no registration required.

No, you don't need to download or install any software. Keyboard Tester Pro works entirely in your web browser, making it accessible from any device with an internet connection. Simply visit our website and start testing your keyboard immediately.

Yes, our keyboard tester recognizes most standard keyboard keys including function keys, media controls, and special keys. Some system-specific keys or custom macros may not register properly as they might be handled at the operating system level.

Absolutely! Our keyboard tester works with virtually any keyboard that connects to your computer, including built-in laptop keyboards, external USB keyboards, wireless keyboards, and Bluetooth keyboards.

When you press a key on your physical keyboard, the corresponding key on our virtual keyboard display will highlight and appear in the key press history. If a key doesn't register when pressed, it may indicate a hardware issue with that specific key.

Yes, our keyboard tester supports N-key rollover testing, allowing you to press multiple keys simultaneously. This is particularly useful for testing gaming keyboards or checking keyboard ghosting issues. The virtual keyboard will highlight all pressed keys.

If certain keys aren't responding in the keyboard tester, try these troubleshooting steps:

1. Refresh the browser page and try again
2. Try a different web browser
3. Clean the problematic keys (use compressed air or carefully remove keycaps)
4. Check for driver updates for your keyboard
5. Test the keyboard on another computer if possible

If the issue persists, it may indicate a hardware problem with your keyboard.

This issue is known as "key chatter" and is common in mechanical keyboards. It's usually caused by dirty switch contacts or deteriorating switch mechanisms. Try cleaning the keyboard first. If that doesn't work, you may need to adjust keyboard settings in your operating system to increase debounce time, or the keyboard might need repair or replacement.

If the keyboard tester isn't detecting any keypresses, try these steps:

1. Make sure your keyboard is properly connected to your computer
2. Try a different USB port or connection method
3. Restart your browser and allow any permission requests
4. Temporarily disable any browser extensions that might interfere
5. Make sure you haven't clicked outside the browser window (focus issue)
6. Restart your computer

Keyboard Tester Pro works with all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. For the best experience, we recommend using the latest version of Chrome or Firefox as they provide the most consistent key event handling.

While our website is mobile-responsive, the keyboard testing functionality is designed for physical keyboard testing and may not work as intended with on-screen mobile keyboards. For the best experience, we recommend using Keyboard Tester Pro on a desktop or laptop computer with a physical keyboard connected.

Certain key combinations (like Ctrl+T or Alt+F4) are captured by your browser as shortcuts before our keyboard tester can detect them. This is a security feature of web browsers and cannot be bypassed. For testing these specific combinations, you may need to temporarily disable browser shortcuts or use dedicated software keyboard testers.
