How do you unlock your tab key?

To unlock your tab key, first ensure that no keyboard shortcuts or settings are preventing its function. If you're using a specific program, check its settings to see if the tab key has been reassigned or disabled. Additionally, try restarting your computer or testing the keyboard on another device to rule out hardware issues. If your keyboard has a "Fn" key, ensure it’s not engaged in a way that alters the tab key's function.
