On newgens 08+, there's numeric code on ignition-switch that can be used to cut new key. I think you may have to remove ignition-switch in order to see the code.
Even without code, a good locksmith can take cylinders out of lock and make a key from that. Similar to this video. I had this done on my original VF500F 25-years ago when one and only key I had finally wore out.
