Frequently Asked Questions
How do I test if my keyboard keys are working?
Simply press any key on your keyboard while on this page. If the key is working, it will light up green on the virtual keyboard display. The tool tracks all key presses and shows you detailed statistics including key codes and press counts.
Can I test my mechanical keyboard?
Yes! This keyboard tester works with all keyboard types including mechanical keyboards (Cherry MX, Gateron, etc.), membrane keyboards, laptop keyboards, wireless Bluetooth keyboards, and gaming keyboards.
How do I detect stuck or chattering keys?
Press and release each key once. If you see multiple key presses registered for a single press in the statistics panel, your key may be experiencing chattering (a common issue with worn switches). Stuck keys will continuously register as pressed.
What is a key code?
A key code is a numeric value that represents each key on your keyboard. It's used by software and games to identify which key was pressed. Our tool shows both the JavaScript keyCode and the physical key code for each press, which is useful for developers and gamers.
Do I need to install anything to use this keyboard test?
No installation required. This keyboard test runs entirely in your web browser. Just open the page and start pressing keys to test them. It's completely free and works on Chrome, Firefox, Safari, Edge, and other modern browsers.
About This Keyboard Tester
Our free online keyboard test is the easiest way to check if all your keyboard keys are working properly. Whether you're troubleshooting a malfunctioning key, testing a new keyboard before purchase, or diagnosing key chattering issues, this tool provides instant visual feedback.
The keyboard tester displays a virtual keyboard layout that mirrors your physical keyboard. When you press a key, it immediately lights up green to indicate it's working. Keys that remain gray haven't been tested yet, making it easy to identify which keys you still need to check.
This tool is especially useful for:
- Testing new or used keyboards before purchase
- Diagnosing broken or unresponsive keys
- Detecting key chattering (double-pressing) issues
- Checking if all keys work after cleaning your keyboard
- Verifying keyboard functionality after spills
- Testing mechanical keyboard switches
- Getting key codes for programming or gaming macros
Unlike downloadable keyboard testing software, our online keyboard test works directly in your browser with no installation required. It's compatible with Windows, Mac, Linux, and Chromebook, and works with any keyboard connected via USB, Bluetooth, or built into your laptop.
