Frequently Asked Questions
How do I test if my laptop or desktop keyboard keys are working?
Simply open our online keyboard tester and press any key on your keyboard. If the key is functioning properly, the corresponding key on the interactive virtual layout will instantly light up and play audio feedback.
What is keyboard ghosting and how can I check it here?
Keyboard ghosting occurs when certain key presses are not registered when multiple keys are held down simultaneously. You can test your keyboard's key rollover capability by pressing multiple keys at once and checking if all pressed keys illuminate on screen.
Is this keyboard key checker secure and private to use?
Yes. The entire key signal testing engine runs locally inside your browser via JavaScript. None of your keystrokes, personal data, or input logs are ever recorded, stored, or uploaded to external servers.
