How to Fix a Key Not Working On a Gaming Keyboard – Step by Step

There’s nothing more frustrating than being in the middle of a critical point in a game, but failing because one of your computer’s keys stops working. Sometimes a gaming keyboard stops working due to a driver or connection issue. But when you are struggling with one key not working, then there’s something else going on. In this article we’ll discuss how to fix a key not working on a gaming keyboard. 

A key may not be working on a gaming keyboard due to dust, debris, or a problem with the function lock or number lock. The key may also be mapped incorrectly within a game. To fix the key, first, clean it out, make sure that the number lock and function lock are turned off, check if the key needs to be remapped within the game, and check the working status of the key’s internal switch.

Why Is My Keyboard Key Not Working?

If you’re having issues with several of your keyboard keys not working properly, this might be due to underlying driver issues. You can try rebooting and installing new drivers first to see if that’s the problem. However, if there’s a single keyboard key not functioning properly, it’s more likely an issue with that specific switch. 

Common reasons a keyboard key may not be working include dust or debris under the key, the function lock or number lock is changing the function of the key, the key is not mapped for the correct action within a game, or the key’s switch is internally broken. 

These could be the reasons why your keyboard key is not working:

Reason 1. Dust or Debris Is Under the Key

Dust and debris fall between the gaps of your gaming keyboard’s keys and can gunk them up. Due to the tiny space of the gaps, the debris and dust become trapped and compressed inside. This damages your keys over time and can stop them from functioning properly.

Most gaming keyboards like this one come with air intakes on the sides and the back, and sometimes on the bottom, so dust may not always cause a malfunctioning issue. But, if dust and debris stay trapped in there for a long time, and keep building up, it can make your keys stop working. 

Dirt and dust that gets lodged under the keys of your keyboard can affect your gaming negatively leading to you having to fix the keys.

Reason 2. Function Lock or Number Lock Is Changing the Function of the Key

As this video by AddictiveTipsTV explains, when your keyboard is in function mode or number mode, it can cause issues regarding the actual functions of your other gaming keys. Being stuck on your gaming keyboard’s function lock or number lock can cause issues with the remaining keys’ actions. Your gaming keyboard keys might be doing the opposite of their intended action, or they might be interfering with your keyboard’s light setup. 

Most gaming keyboards like this one also come with the function lock as default. If you’re a beginner, it can be intimidating if your new gaming keyboard keys aren’t working properly. The good news is that you only need to unlock it through the combination given by the keyboard’s manufacturer. 

If your gaming keyboard is in function mode it could affect the actual functioning of your other keys, but this is easy to fix.

Reason 3. The Key Is Not Mapped For the Correct Action Within a Game

According to this article from Microsoft, if the connections between your drivers, computer, and keyboard are fine, then there might be issues with the mapping of keys on your gaming keyboard. Even if you are a novice gamer, you must figure out the correct mapping for the actions within the game. Otherwise, the keys won’t work correctly during the game. 

This usually happens because of incorrect mapping within games creating unintended actions or faulty commands. But, the good thing is that you can easily learn how to reset your gaming keyboard mapping to your desired and required mapping. Keyboards like this can be configured to perform customized functions as our article about how to change gaming keyboard light settings explains. 

Reason 4. The Key’s Switch Is Internally Broken

If you’re constantly having trouble with an unresponsive key on your gaming keyboard, chances are that there’s a faulty switch. The key’s switch may be stuck or internally broken altogether. Due to the faulty switch, your computer’s OS is probably not even getting a signal from your keyboard when you are pressing the broken key.

How To Fix Mechanical Keyboard Keys Not Working Due to Dust or Debris

To fix a key not working on a gaming keyboard that’s mechanical, first try the easy fixes. Dust and debris that builds up within the gaps of your keyboard keys alter the proper functioning of the keys, cause damage, and ruin your gaming performance.

To fix mechanical keyboard keys that are not working due to dust or debris, clean the keys by pulling all the keycaps off, soak the keycaps, clean the naked keyboard, and then reassemble the keyboard.

There are step-by-step guides you can follow to clean your keyboard, depending on the nature of the buildup and who the keyboard manufacturer is.

When fixing broken keys of a gaming keyboard be sure to follow the right procedure so as not to do further damage.

Follow these steps to clean your mechanical keyboard:

Step 1. Pull All the Keycaps Off

To pull the keycaps off, use a good wire keycap puller like this one to prevent damaging your keycaps further. When pulling off the keycaps, make sure you are pulling straight and directly from the key’s switch, rather than using any other angle because that will damage your keycaps.

An easy way is to reach under the keycap of your keyboard’s desired key. To do this, you can use a small and flat-based screwdriver from a set like this as well. The purpose is to hold down the rectangular part that is under the keycap mounting post. Once you’ve got your part of the stem stable, you can use the keycap puller. It’s best to use it by applying pressure in a rocking upward motion. Continuing this motion, start at the edge of the key and then make your way toward the center. 

To clean your keyboard remove all the keys carefully without damaging anything.

Step 2. Soak the Keycaps

Once you’ve taken the keycaps off, put them aside and soak them in a bowl. Fill the bowl with lukewarm water and add some good dish-cleaning liquid like this. Mix the dishwashing liquid with keys, swishing them around in it. Leave the keys to soak in the cleaning mixture for at least ten minutes. 

While you’re cleaning your keycaps, you may want to try cleaning your mouse and mousepad at the same time. Our article about how to clean a sticky mouse & mousepad could prove to be helpful, while our simple tips and tricks to clean a mouse provide the steps to thoroughly clean a gaming mouse to ensure it lasts a long time. 

Step 3. Clean the Naked Keyboard

Now that your keycaps are being cleaned, you need to properly clean the surface under the keys, as explained in this instruction manual by Razer. Use Isopropyl alcohol and cotton swabs to gently wipe the surface of the keyboard under the keys (but make sure the cotton swab isn’t too wet). If the dust and debris buildup is substantial, use an air compressor like this or a simple can of air to blow out the nasty buildup. 

If there is still residue stuck under the keys, use a tweezer to pull out the buildup from the key switches. After you’re done cleaning the keyboard allow it to dry thoroughly, then give it a good brush with a keyboard brush like this one to freshen it up.

Step 4. Reassemble Your Mechanical Keyboard

Once your keyboard is cleaned, check on the soaked keycaps. Gently remove any dirt and debris. Dry them using a kitchen towel or paper towel. The keys must be completely dry before placing them back on the keyboard. If you don’t, water can seep into the keyboard and ruin it. 

If you’re uncertain if they’re dry or not, set the keys on top of a dry towel and let them dry overnight. Once the keycaps are completely dry, place the keycaps back on the keyboard. Give it an overall brush, and your keyboard should be clean. A handy trick to help you remember where each key goes is to take a photo with your phone before disassembling the keyboard.

How To Fix a Key Not Working on a Gaming Keyboard Because It Is Mapped to the Wrong Function in a Game

An incorrectly mapped key on a gaming keyboard can be pretty annoying. But, once you have figured out the correct and the incorrect keys, it’s easy to remap or reset your gaming keyboard mapping within your game settings. 

To fix a key that’s not working on a gaming keyboard because it’s mapped to the wrong function, reset it within the game settings. Figure out the keymap layout section, and then replace or reset the key from there. Ensure that the key functions are correctly assigned, and stay within the game’s required settings. Look for help in the documentation that came with the gaming keyboard.

Even if you’re a beginner, this article from will help you remap your keys and assign the correct functions to them.

Option 1. Access the Keyboard’s Remap Key

Most gaming keyboards come with their own specific remap button on the keyboard itself, to help with these particular issues. If your gaming keyboard has a remap button, then all you need to do is hold it down, then press the key you want to remap, and then press the key that contains the function you want to assign to the key that you want to remap.

Option 2. Use Remapping Software To Remap the Key

How to Repair an Unresponsive Key on a Gaming Keyboard Due to an Internally Damaged Switch

If the above methods aren’t fixing your dead key, chances are your key’s switch is broken. This makes it unable to send signals or operate correctly. 

To fix an internally broken switch, the most effective solution is to replace the switch. Working with a mechanical keyboard makes this easier, as every key has a mechanical switch under it, which can be replaced individually using a puller or a solder.

According to this video tutorial by Kix, the best way to restore the switch is to check if the damage to the switch is manageable or if you’d need to replace the switch altogether.

Here is how you can repair an unresponsive key on a gaming keyboard:

Option 1. Replace the Switch Using a Puller

Option 2. Replace the Switch Using a Soldering Iron

If your mechanical keyboard doesn’t come with hot-swappable switches, replace the switches with a soldering iron like this one. Soldering is more complicated than using a puller, so if you’ve never done it before, you should take the keyboard to a computer shop to avoid any damage. 

If you think you have the know-how to do it yourself, you can desolder the joint that is connecting the keyboard and the broken switch, replace that switch, and then solder in a new, working switch.
