'dead' right arrow key and page down key

So I recently got a Razer Cynosa Chroma Pro a few months ago and been loving it since. Thing is, while I was away from my computer, my little brother tried to clean the keyboard with warm water. I came back 20 minutes later and saw that the keyboard was wet. I turned it upside down and shook it till no more came out. Then I took paper towels and dried spots where some didn't come out. I did a quick test to make sure the keyboard worked since in the product description razer stated that this keyboard was spill-resistant, so I thought nothing of it. Little did I know that the right arrow key and page down key did not function at all. I checked if any macros were running and there weren't any. I checked in synapse to see if it still responded sadly no. Now I am afraid it's been water damaged. I tried blowing through it to get any dust out and try and fix it but it did not prevail. Now, since it was a few months ago that I bought it the warranty is still in check but I want to see what I can do myself before going down that route.
