Blackwidow Chroma v2 key fix?

I want to just clarify that I might have spilt tea on my trusty keyboard the other day and while I dried it off as best I could, it seems to have only affected one key and that's the M.

Is there any way I could possibly fix this? I've seen a lot of resoldering videos but I'm not sure if there's really anything else I can do.

At the moment, I've rebinded it to one of my M1 keys but if there's another way to restore proper functionality, I'm all ears.

I've also had this keyboard for about three years so it's a little out of warranty which sucks.
I'd really like to not have to replace the whole keyboard if it's possible.

Many thanks guys
