Problem with keyboard I can only write with the digit zero
i can only write, if i press zero (0) on my Macbook Keyboard. But there are no problems with an external keyboard.

Try booting in safe mode ( hold the shift key down until you see the spinning sundial) to see if it's related to a 3rd party application install.
If the problem goes away you'll have to think about when this first occurred, and what to install or what preferences to change.
If the problem persists you could try a 3rd party key remapper app or replace the keyboard.
