How To Lock And Unlock The Fn Key?

Knowing how to use keyboard shortcuts can help you save time and get things done faster. A single function button from this set can perform several different tasks, whether it’s for multimedia or a specific task.

Here are two simple methods to lock or unlock the Fn key. You can either toggle between locked and unlocked mode using the F5/F6 keys or simply hold down the Fn button until the icon changes color.

How Does the Fn Key Work With Function Keys?

Fn stands for “Function”, but it’s a modifier key that lets you change the functionality of certain key settings on your keyboard. As mentioned above, pressing Fn + any number between 1 and 12 will give you access to the alternative sets of commands of the corresponding function keys.

For example, pressing Fn + 2 will let you adjust the brightness level of your screen, whereas pressing Fn + 9 will allow you to turn off the WiFi connection. If you press Fn + 5, you’ll be able to easily switch between the caps lock and shift modes.

While the Fn key is usually used to modify the functionality of the hardware function keys, there are times when the opposite is true. For instance, if you press Fn + 4, you’ll no longer be able to adjust the brightness level of the display. Instead, you’ll only be able to adjust the volume level.

To avoid confusion, we recommend that you keep the Fn key unlocked whenever you use it to modify the functionality of function keys. However, if you find yourself accidentally pressing it, simply press it again to return to the default mode.

Procedure To Lock And Unlock Fn Keys

To lock and unlock the Fn key, you need to press the function key (Fn) once and hold it down until you hear a click sound. Then release the Fn button. You should now be able to access the additional functions assigned to the Fn key.

Some brands of PCs have a dedicated key for locking and unlocking the FN key. But if yours doesn’t, you can still lock and unlock it through software. There are several programs available online that allow you to lock and unlock the Fn keys.

For instance, Microsoft Windows 10 comes with a utility called Keyboard Settings. Open it and select the Function Keys tab. From here, you can toggle between locked and unlocked states.

Another program that works well is AutoHotkey. This program lets you assign any keyboard shortcut to any command. So, for example, you can assign Ctrl+Shift+H to lock the Fn key.

1. Keyboard

If you’ve ever tried to use your computer without the Fn key, you know how frustrating it can be. You might think that there’s no way to fix it, but there is. All you need to do is find out whether or not your computer has the F Lock key. And if it does, you can easily lock and unlock it.

To find out whether or not you have the F Lock key, you should look for the F Lock symbol. Some keyboards come with a light indicator next to the F Lock key. Other times, it’s printed right next to the Esc key. Either way, once you press the F Lock key, it will turn off the light. Then, you can press it again to turn it back on.

After finding the F Lock button, all you need to do is press and keep pressing it until the screen goes black. Then, you can either press Fn or F Lock to lock and unlock the F Lock button.

This method works well for laptop models, but it may not work for desktops. If you’re trying to lock the Fn key on a laptop standby, you’ll need to look for the F Lock key on the keyboard key itself. On desktops, however, you can look for it on the touchpad. Once you find it, you can lock and unlock it the same way.

2. Windows Mobility Center

This guide shows how to access the Windows Mobility Center. Once you’ve opened it, you can find out if your computer can lock or unlock the FN key. And if it does, you can easily change its firmware settings.

Your computer may already be able to show you the Windows Mobility Center. But if it doesn’t, you can still open it manually. Then click OK. Now you should see the Windows Mobility Center.

Once you’ve found the Function Key row, you can either lock or unlock the FN button. Simply click on the dropdown menu and select either Lock or Unlock.

Now that you know how to access the Windows mobility center, you can quickly find out if your computer supports locking or unlocking the FN key. And you can adjust its settings accordingly.


This tutorial shows how to lock and unlock the function key on your PC. You’ll find out how to access the BIOS settings and change the function key behavior.

You won’t be able to control your computer using your keyboard’s arrow keys, but you can use its function key buttons instead. To access these standard functions, go to the Main tab and look under the Function Key Behaviors section. Select it and then press F10 to save your changes and confirm the prompt.

Now you can use the function key to lock or unlock the Fn key on Windows 10 and 11.

How Do I Use The Fn Key Without Pressing The Fn?

This tutorial explains how to use the Fn key without having to press the FN button. You just have to find the right key with a padlock symbol on it. Then press the Fn key and Fn Lock key at the same time. Now, your Fn keys will work without having to press the actual FN button.

There are two types of Fn keys: common Function Keys and Programmable Keys. Both of these keys allow you to change the secondary function of your keyboard. But only the Function Keys can be used without pressing the FN button.

So if you want to use the Fn keys without pressing the FN button, you should look for the key to access Function Keys on your keyboard. There are four Function Keys on a standard keyboard: F1, F2, F3, and F4. These keys are usually found near the spacebar or next to the arrow keys.

Now, once you locate the correct key, press the Fn Lock key and the Fn key at the same time to activate the Fn keys. And now you can use the Fn keys without having to hold down the FN button.
