Adding to the discussions about the searches for a replacement/duplicate key.
My search is for a NB636 key. It's original to the bike; '67 CL77, fitting both the ignition switch and the fork lock.
Every source contacted so far says NB636 is not available. And a new key cannot be cut because the NB blank is no longer made.
Perhaps a forum member has this NB636 key or knows of a source to find one or cut one.
