Lost Motorcycle Ignition Key

So the key ring that my motorcycle ignition key was on must have broke, and I can't find it anywhere. Sadly, I never thought to make a backup. What do I need to do to get this resolved? Can a locksmith or bike tech somehow make a replacement, or do I have to get a whole new expensive ignition assembly or something installed by the dealer?
