What is a Keyboard Tester?

A keyboard tester is an online tool that helps you check if every key on your keyboard is working correctly. Whether you have a QWERTY, AZERTY, or custom layout, this tester detects key presses in real-time, showing you exactly which keys respond and which ones fail.

This is especially useful if:

• Your keyboard has unresponsive keys.
• You’re troubleshooting mechanical keyboards or laptop keyboards.
• You want to verify anti-ghosting or multi-key press support.
• You’re checking a gaming keyboard before competitive play.

Common Keyboard Problems and Fixes

1. Sticky Keys

Sticky Keys is an accessibility feature that allows you to press keys like Shift, Ctrl, or Alt one at a time instead of holding them down.

• How to turn off Sticky Keys (Windows): Press Shift 5 times quickly, or go to Settings > Accessibility > Keyboard and disable it.
• On Mac: Go to System Preferences > Accessibility > Keyboard and turn off Sticky Keys.

2. Ghosting Issues

If certain key combinations don’t register, your keyboard may not support full anti-ghosting. Our tester’s Multi-Key Test can help identify this.

3. Wrong Layout

If pressing one key types another symbol, you may have the wrong keyboard layout selected. Switch between QWERTY and AZERTY in your OS settings or use our layout switcher.
