Keyboard Tester

Honestly, most people don't think about testing their keyboard until something goes wrong. But there are a few situations where it's really useful:

• →Just bought a keyboard: Check every key before your return window closes — especially if you bought it online.
• →A key feels off: Some keys register twice (chattering) or don't register at all. Easy to spot here.
• →Gaming issues: If you're dropping inputs mid-game, use this to see if the problem is your keyboard or something else.
• →After a spill or cleaning: Water damage and deep-cleaning can knock out keys. This is the quickest way to check.
• →Buying second-hand: Always test before you pay. Sellers don't always mention sticky or dead keys.

• →Dead keys: A key that never lights up no matter how hard you press it. Could be physical damage, a dirty switch, or a firmware issue.
• →Chattering (double-registering): You press a key once and the history log shows two or three presses. Common on worn-out mechanical switches.
• →Sticky or slow keys: The key lights up but takes a split second longer than others. Look for inconsistency in your key press history.
• →Ghosting: When you hold certain key combinations, other keys stop working. Basic keyboards ghost at 3–4 simultaneous keys.
• →Wrong key registering: You press one key and a different one lights up. Usually a wiring issue inside the keyboard matrix.
