Can I fix this???

Do you have another computer you can try that keyboard on?

Take it back if you can. Last one I had in used to turn out as a + sign whenever the w key was pressed, told the customer to go buy a new one!

Its most likely a defect with the keyboard itself and in how it was made. I also suggest taking it back!

PS: is it JUST the 0 key or is it the shift key?

[catnapper]

Its the ) symbol... which strangely is working again

The 0 worked fine and the shift worked fine on everything else. I wonder what happened!

[G535]

Cat hairs in the keyboard perhaps?

Who knows! Glad it's working again.

There's not much of a contact path in keyboard traces, so if there's any dust at all in the contact area it can cause problems.
