90%+ of the problems are caused by not plugging the ribbon connector/s into the appropriate receptacle straight and completely. Check there first. The other 10% or so is caused by a torn ribbon or a scratch that removes the conductive ink from the ribbon. Check for those as well. You can also try an external (USB) keyboard as a check.

Then have him check it.

And, by the way, lose the CAPS, it's the equivalent of shouting and will wear out your welcome here very quickly.
