Frequently Asked Questions
How does the keyboard test work?
Our keyboard tester detects key presses in real-time using JavaScript events. When you press a key, it lights up on the virtual keyboard display, confirming it's working properly.
What is N-key rollover (NKRO)?
N-key rollover refers to how many keys your keyboard can register simultaneously. Gaming and mechanical keyboards often support full NKRO, while basic keyboards may only register 6 keys at once.
Is my keyboard data private?
Absolutely! All testing happens locally in your browser. No keystroke data is sent to any server, ensuring complete privacy.
Why is a key not registering?
If a key doesn't light up when pressed, it may be stuck, damaged, or have debris underneath. Try cleaning the key or checking for hardware issues.
Can I test any type of keyboard?
Yes! Our tester works with all keyboard types including mechanical, membrane, laptop, wireless, and Bluetooth keyboards.
How do I detect stuck keys?
Stuck keys will appear highlighted even when not being pressed. Our tool automatically detects and warns you about potential stuck keys.
