How to use our keyboard tester
- Press the keys on your physical keyboard. Each key you press should light up on the virtual keyboard—this confirms that key works.
- Click the reset arrow to clear existing highlights and test again. Try pressing multiple keys together to check if your keyboard supports simultaneous key presses.
- If every press produces an immediate response on the tester, your keyboard is working normally. If certain keys don’t respond or the response is delayed, there might be a problem.
Tips
- Test every key—including function and special keys—to ensure nothing is missed.
- The tester adapts automatically to both Windows and Mac keyboard layouts.
- Press Ctrl + D to bookmark this tool for future tests.

Keyboard test failed?
If some keys do not respond, try these steps:
- Check the connection: Ensure the keyboard cable or wireless receiver is firmly connected. For USB keyboards, try another port.

Frequently Asked Questions
What is an online keyboard tester?
An online keyboard tester is a web tool that lets you check if all the keys on your keyboard are working properly. Simply press any key on your physical keyboard, and it will light up on the virtual keyboard in your browser.
How do I use this keyboard tester?
1. Open this page in your browser.
2. Start pressing keys on your physical keyboard.
3. The corresponding keys on the screen will highlight instantly.
4. You can also test special keys like Enter, Space, Ctrl, Shift, and function keys.
If a key doesn’t light up, it may indicate a hardware or software issue.
Can I use this keyboard tester on a laptop?
Yes. This tool works on both desktop and laptop keyboards. If you are testing a laptop, you can check standard keys as well as function (Fn) shortcuts. Note: the Fn key itself cannot be detected by browsers.
What should I do if a key doesn’t respond?
If a key doesn’t highlight on the tester:
1. First, make sure your keyboard is connected securely (or your laptop keyboard isn’t blocked by dust).
2. Try cleaning under the keycap or testing with another keyboard.
3. Update or reinstall your keyboard drivers (for Windows).
If the key still doesn’t work, the keyboard hardware may need repair or replacement.
Can I test my mouse clicks here too?
Yes. The tester also detects left-click and right-click events. When you click your mouse, the corresponding button will light up on the screen.
Is this tool safe to use?
Absolutely. No keystrokes are stored, uploaded, or shared. Everything runs locally in your browser, which means your privacy is fully protected.
Why use this keyboard tester instead of others?
Unlike many online tools, this tester includes:
1. Key history tracking (see your last few pressed keys).
2. Keys per minute (KPM) counter to measure typing speed.
3. Sound toggle option for audio feedback.
4. Clean, ad-free interface with no pop-ups or distractions.
Do I need to download any software?
No. This is a completely web-based keyboard test. You don’t need to install anything. Just open the page and start testing immediately.
