Many keys in keyboard not working HP G62-b80SS laptop

HP G62-b80SS laptop
Many keys in the keyboard aren't working. I've successfully replaced the motherboard for this laptop because it went dead because of some dampness trickling going inside and is now otherwise working fine. It's been abandoned for 7 months. I've reseated the keyboard connector and cleaned it with a contact cleaner.
I guess I need to get a new keyboard, am I right?
Thanks!

Or the motherboard keyboard connector is damages by corrosion...

I've already fitted in a new keyboard and is working fine.
Thanks anyway
