Louis Vuitton Lock & Key #?

Louis Vuitton Lock & Key #2?? It’s a #200 series I just don’t know the number, please look at the lock and key for reference. The lock and key come freshly polished (the pictures don’t do it justice) and ready for its new home😊 I may be able to include a chain if I am told in the process of purchasing if I have one, not a guarantee.
