some keys not working! photo wich ones

Hello! Yesterday night I was on Netflix then I tried to text a friend but some keys didn’t work so I called it called it a day and went to sleep. I didn’t thought about it but silly me are blocked the MacBook i mean closed it. Today i wanna watch smth on my mac.. my password can’t be filled….. yesterday i also checked and the software was up to date . I took an key out and cleaned but still it doesn’t workkk . I didnt spill juice or water on it…. It js randomly stopped working , cuz when i searched the serial on Netflix it worked….

I do have an warranty for the product but i dont wanna get deep into it and can i return it back if it randomly stopped working?? At least i need answers if i can fix it now.
