Keyboard tester

To determine whether a switch on your keyboard is still active and sending the correct signal, you can use this keyboard tester: https://keyboardchecker.com/. It will show whether a switch is active and sending the correct signal, or whether it isn't active and might need to be replaced.

How to Use the Tester

1. Open https://keyboardchecker.com/ in your web browser.
2. Press each key on your keyboard, one at a time.
3. Watch the on-screen keyboard. A key that works will turn green, and the "Last key pressed" field will show the key you pressed.
4. Note any key that does not turn green or that shows the wrong key.

If a Key Fails the Test

A key that registers more than once or not at all may be affected by dust or debris. See our article "Keyboard Chatter" for cleaning tips.

If the key still does not work, please submit a ticket through our help desk at: Open a technical support ticket. Let us know which keys failed the test. To check your coverage, see our article "What Is My Warranty Period?"
