The FN key is a key found on most keyboards that allows you to activate the secondary function for any other dual purpose key. If you press a specific combination of keys, you may accidentally activate the FN key lock unknowingly. When locked, you will only be able to type the symbol that is associated with the primary key. Using a specific code, you may be able to unlock the FN key on your keyboard without much effort.

Restart your computer. Depending upon the model of your computer and/or external keyboard, the FN key may unlock once the computer is rebooted. Verify whether the key is still locked by trying to type a few characters.

Press and hold the "FN" key followed by the "Num Lock" key. On most keyboards, the "Num Lock" key is located near the top of the 10-key number pad. Release both keys together. Pull up any text program, such as Word, and attempt to type your name.

Press and hold the "FN" key followed by pressing the "Scroll Lock" key. Depending upon the model of your keyboard it may read "Scroll" with a lock symbol on the key. Release both keys together. Pull up any text program, such as Word, and attempt to type your name to verify that the lock has been removed.
