We have a similar type of key. Had them hand cut by a locksmith shop. They use a suitable blank and start filing, and they know how to charge for it. Only in steel unfortunately.
Greetings,
Am I to assume you are looking for a key for your SALOON doors?
Try these people in Deland Fl. The Brass Works Inc - Brass & Stainless Steel Hardware they have made them for Monk owners (similar key) in the past. Lots of other hardware on their site.
Greetings,
