My NC30 came with just one, non-original key. Can I get an original Honda one cut to suit from this key? If so, where please? honda dealer maybe?

I wouldn't of thought you could get one as they have been out of production for quite some time now..
Think you will have to settle with taking your key to the local locksmiths and having a copy of it made up. (Or two?).
There should be no reason for it to not work adequatley in your bike.

yes you can, i think there are 2 types and yours will be the early one.
david silver may be able to help to supply you a blank or rick oliver.

Indeed you can. I got 2 new ones from local Honda dealer (later type blanks) and then went to local locksmith to get them cut.
If I remember correctly the blanks were about £12 each.

magic - thanks

Great :)

im looking to get a set done as mine only has one and my fuel cap one is a little bent

Dave silvers did have both Type 1 / Type 2 Keys in stock.. £6 each.

I brought several as 'spares' as you don't see them all that often.

Give em a ring and see what they say!

Most decent locksmiths will be able to cut one for you off your copy.
