First things first

I recommend you to first visit the site https://en.key-test.ru and check whether your faulty keys are working on this site or not. If your faulty keys are still not working on this site then go with the below step to fix it:

I have categories this issue in two part by which you can analyze about the key which is not working probably related to the Software or Hardware.

Software Parts

Enable or Disable the key through any third party Software

I have found in some Laptop or computer that the user is facing an issue when pressing a specific key which are not working, related to its software settings. I recommend you to closely look any third party application installed in the computer which is preventing you to type specific character. If it is installed you need to uninstall it instantly and reboot the computer and check. Here I am letting you know about some apps by which you can easily disable the desire key of your Laptop keypad or external keyboard as well.

KeyTweak and SharpKeys is very famous tool now a days to disable specific keys on your keyboard. Both are free to download and use this application when extremely needed. But I can say apart from these two app, users installed any other third party also to block specific keys on keyboard. Which you need to closely look on the computer and uninstall it.

By KeyTweak can be download here

Download and install KeyTweak to Enable or Disable the specific key (in my case A)

Click on Disable Key to disable the specific key and vice versa

Click Yes to restart the computer and check

By SharpKeys can be download from GitHub here if you have Windows 7 or Windows 8. But if you have Windows 10 or Windows 11 you can download it from Microsoft Store itself.

Install SharpKeys from Microsoft Store in Windows 10 or Windows 11

Download and install it from GitHub in Windows 7 or Windows 8

Click the Add button to add the value in Windows Registry

Choose specific letter or button in left pane and select Turn Key Off in right pane

Click OK to and click on Close the SharpKey

Now you need to Sign Out or Reboot the computer to take effect

But to fix the faulty key always notice that you have to delete all the value to get the button again in working state like below.

Enable or Disable the key through Windows Registry

In some scenario, buttons are not working on keyboard if it is disable by Windows Registry. In the below path as shown in the image below is as same as doing through third party application. When you use KeyTweak and Sharp Key or any other similar application for disabling and enabling the key, its change or create the same value in the Windows Registry path below.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout

Open Run and type REGEDIT and press Enter key

As you can see the Scancode Map value for S alphabet in the Windows Registry

To fix this issue which is enabled through Windows Registry just delete the value and restart the computer to take effect and after restart your key will be in working state again.

There is nothing in Keyboard Layout after deleting the value from KeyTweak or SharpKeys

Still not able to analyze on the Software parts

If you still not able to analyze about the faulty keys through Software then I recommend you to download Rufus here application and make your Pen drive MS-DOS bootable. And when you done making it bootable, then boot your system through MS-DOS bootable Pen drive and check by typing the faulty keys there. If the faulty keys are working in MS-DOS that means there must be any settings applied in Windows side or still there is any third party app which is blocking the key to type the text.

Creating bootable Pen drive and checking Keypad in MS-DOS

If the faulty keys are not working in MS-DOS environment then it means your Laptop keypad or keyboard having the issue related to the Hardware parts.

Hardware Parts

First try to clean the faulty keys properly and check. In some type of keyboard you may have Key Puller tool so that you can easily eject or remove the key and clean the track of your keypad and check.

Second which is most important and very successful method to open up your Laptop keypad. Do this as described in the video below and look for Keypad Cable attached on the motherboard. Which you need to clean it properly through brush and thinner or petrol and check. (This second step can be differed in some laptop depend upon the model type and its opening method, and if you are not sure do it by an expert.)
