Our service will help you check whether this key works or not. If, when you press a key on the physical keyboard, it doesn't light up on our virtual keyboard, then this key doesn't work.
Try to remove the key from your keyboard and clean it, as well as the place where it is attached. Then put the key back and try testing it again.
You may have accidentally spilled some liquid on the keyboard or it has become dirty over time. If you have a separate keyboard or laptop, we recommend that you take it to a repair service to clean and configure all keys on the keyboard to work properly.
You can easily repair your keyboard layout using our online tester. Just press the missing keys and restore the keys according to the signals of our virtual keyboard.
We have tried to make the most simple and convenient keyboard tester for you, which will help you quickly test the keyboard for free.
