This tool is designed for diagnosing keyboard problems, not fixing them. It helps identify which keys are faulty, but physical repairs require cleaning, professional service, or keyboard replacement.
Possible reasons include:
Physical damage or debris under keys
Keyboard driver issues
Browser security restrictions (some browsers limit certain keys)
Low battery in wireless keyboards
New keyboards can have manufacturing defects. Testing ensures:
All keys function properly
No stuck keys or double-press issues
Special function keys work as expected
