Can these helmet locks be rekeyed to match the others?
If someone today has two bikes, check to see if the same key fits the helmet locks and unlocks either bike's helmet lock. The glove box lock will open with just about any Concours key. I think they have only one tumbler inside. I have two bikes, if I remember when I get home, I'll check it. So, there's a possibility that any lock will work. I don't think there is a right and left, they are both the same (at least my '87 is).
And, I think they can be rekeyed also. You may have to work that chrome cover on the front off to do it.
