The door handle itself is fine but the little gear that connects to the golden part in which the key enters is broken. Any help identifying this part would be helpful. The lock says made in new zeal and and the letters II.

We don't have a replacement for that little gear, unfortunately. The only thing we can offer is an all new handle set like our 82-081. I am sorry that we can't offer a better solution.
