Windows 10: Specific laptop keyboard keys work intermittently

Throughout the past few months, specific keys on my laptop keyboard have been working intermittently. These include 't', 'y' and 'o'. At times, I will have to press and hold these keys for them to be registered, at other times they operate as they should. I have several of the common solutions to these sorts of errors; including uninstalling the driver in the Device Manager and ensuring that the Filter Keys setting is turned off. A USB keyboard will not have this issue when plugged in. Using any DISM /Online /Cleanup-Image commands will result in the following message from the Command Prompt,

Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...

Built in keyboard not working

Certainly try this, also does it work flawlessly in the bios or a live disc? If so you have one odd OS issue, if not I'd suspect a cable issue, while the keyboard itself could be failing a specific key would be more common to work intermittently than the whole keyboard.
