Keyboards will eventually go bye bye. Unfortunately you will have to either live with it or buy a new keyboard. Otherwise you could try air-dusting the keys.
The missing keys seem to all be on the third row of the keyboard. That sounds like hardware trouble. Try another keyboard and see if that fixes the problem. Good luck.
