some keys on my keyboard not working

Hi, the following keys on my MacBook pro 17 stopped working: q,w,e,r,t,y,u,i,o and ENTER
i'm using a virtual keyboard atm.
Some others are charged for example F12key is now responding F3 key
Can someone tell me why is it happening and maybe help me to solve this problem?

Awaitting response soon,
Thank you

Otherwise, you might have a bad top case. Or liquid has been spilled into it
