My bicycle/powersport vehicle was stolen while locked with a Kryptonite lock. I did not register for the Anti-Theft Protection Offer, what can I do?

What other proof of value is acceptable for this? Do you need to have homeowners insurance to register for this offer? I sent in my key registration form. Am I now automatically registered for the Anti-Theft Protection Offer? Why do I need to send back a piece of the broken lock as part of my claim? More Questions on Anti-Theft Protection Offer?
