I recently bought a salvage 1199 from a Copart auction. It had no key, ignition, immobilizer, or dash. I bought a set of keys and immobilizer from someone on FB for about $400. It's plug and play. Just plug the ignition/immobilizer into the bike, and the keys that come with it will work.
I went this route rather than SOSDiagnotics, which you can send your existing ignition/immobilizer to, and they'll cut and program a key to work with it. I think they charge about $500 for this service.
Oh...and don't bother calling the dealer. I did, and they swore the only solution was to buy all new keys, ignition, immobilizer, dash, ECU, etc for like $2,500. I should have called them back, spoke with the service manager, and told them to stop lying to people. Maybe that $2,500 option is the only option the dealer can offer. But it's certainly not the only option that exists.
