The Classic Center is “supposed” to follow the TRP (Theft Relevant Part) policy for all keys and locks now. The policy is supposed to require dealer verification and handling of all keys.

However I think they have a soft limit on this, that if you have a car approaching or greater than 25 years old, they relax the rules and allow you to interact with them directly and as long as you have proof of ownership (send them a copy of the title/registration and a copy of your DL with the same name on it) they will ship you a key.
