Welcome to our Keyboard Tester – an interactive tool that lets you check whether every key on your keyboard is working properly. Whether you are using a laptop keyboard, external USB keyboard, mechanical keyboard, or wireless keyboard, this tester helps you find stuck, broken, or unresponsive keys in seconds.
Simply press any key on your keyboard, and the corresponding key will light up on the virtual keyboard above. Along with the key highlight, you will also see important information such as key name, code, which value, and location displayed on the screen. This makes it easy to test not only normal keys but also function keys (F1–F12), arrow keys, numpad keys, and special keys like Ctrl, Alt, Shift, Windows, and Spacebar.
