Keys B,N and Space not working on Dell Inspiron 1525 laptop.

I tried replacing the keyboard and still the same problem. So updated the drives but still the keys wouldn't work.

Has anyone got anymore suggestions?

I'm going to suggest removing the keyboard and checking the integrity of the keyboard ribbon cable header. Lightly push down on the header to see if you can detect any looseness or give, I'm thinking that's the issue due to the relative location of the header to those keys
