Numbers 1-9 Not responding on Keyboard

I saw a post for an earlier model with similar issues that was semi-resolved. Basically the numbers 1 through 9 don’t work. I had to do some crazy rerouting to change my login to not contain numbers and now I’m getting by using a virtual keyboard.

Nothing happens when I just press one number. However, if I press “s” and “d” and then smash down three consecutive numbers “2”, “3” and ”4”, it registers on the computer as if I’ve typed an additional “f”. Nothing happens if I just smash down three consecutive numbers. I’ve also cleaned the keyboard with pressured air. I’m guessing it’s a connection issue with that specific row of keys but I’m not sure where the wire connections are located or what to look for if something is loose.

Any help would be appreciated!
