What Key Is Stuck? Find the culprit in 30 seconds (Free Stuck Key Finder)

If your laptop is typing by itself, your cursor keeps moving, or you can’t enter your password, you’re usually dealing with one problem — a key is being held down, and you need to know which one. This What Key Is Stuck tool gives you a fast, no download way to reveal exactly what your keyboard is sending to your browser, including “invisible” troublemakers like Shift, Ctrl, Alt, and arrow keys.

Try this now: click the focus box, press, and release keys once, then look at Keys currently down to spot anything that won’t let go.

Outcome: you’ll identify the stuck key in plain English, then you can decide the next best step (clean the key, test an external keyboard, or check settings) with confidence, and without guessing.


Keyboard, Mouse & Touchpad Tester

Test key presses, clicks, scroll and stuck keys — useful for quick troubleshooting before you buy replacements or reinstall drivers.

Press every key once • Click left/middle/right • Two-finger scroll

Touchpads vary: some gestures don’t expose separate events to the browser. Two-finger scrolling should show as “wheel”.

Quick troubleshooting tips

  • No keys registering? Click the keyboard focus box again (the browser needs focus).
  • “Stuck key” warning? Tap the key a few times, check for debris, and try an external keyboard to compare.
  • Right click not detected? Some touchpads require a two-finger tap or a corner press — try both.
  • Scroll not detected? Check touchpad settings (reverse/natural scrolling) and test with a mouse wheel if available.
