Keyboard Keys not functioning in Pavilion x360

[HelloWorld12368]

Hello there,

I am experiencing this issue that some of the keys (eg: B/N/Delete/PrtScr) in my HP Pavilion x360 are not functioning. I suspected a driver issue and updated them and I am running Windows 10 Home 1909 x64. Now I suspect a hardware malfunction. Because I spilt water over the keyboard a couple of months back. But then it was fixed and was working fine. 

Now that I had used sanitisers to wipe clean the computer I have a suspect if it was the reason behind it. If so, is it possible to remove the keycaps and rub them using alcohol bud? (Note that I have a backlit keyboard) 

Or are there any possible reasons for this? Please let me know if there is any quick fix for this issue.

Your support in this regard is highly appreciated.
