How to fix a keyboard that adds numbers when you press a key?

Hi, good day!

To help narrow down the cause, kindly answer the following questions

• Is this a laptop keyboard or an external USB/Bluetooth keyboard?
• Did this start after a Windows update, spill, drop, or any other event?
• Does the issue occur in every application (such as Notepad), or only in certain programs?

If you're using a laptop, please try pressing Num Lock or ( Fn + Num Lock), depending on your keyboard model.

Please check if this fixes the issue.

I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.

Hi george kariuki,

Since pressing specific keys is producing both letters and numbers, the keyboard may be sending duplicate key inputs rather than simply having Num Lock enabled. As a quick check, please try these steps:

1. Open Device Manager > expand Keyboards.
2. Right-click your keyboard device and select Uninstall device.
3. Restart your PC to allow Windows to reinstall the keyboard driver automatically.
4. Test the keyboard in Notepad to see if the behavior continues across all applications.

If the issue only affects the built-in laptop keyboard and an external keyboard works normally, that would suggest a keyboard hardware or keyboard firmware issue rather than a Windows setting.

I hope this helps point you in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
