Room Keys from a Parisian Hotel... Identify Manufacturer?

[shanodot]

I was in Paris recently and stayed at the Hotel West End and this was the key to my room. I'm back now and I'm remodeling a home in California, and I would love to have this type of keyset for my front door. Can anyone lead me in the correct direction? (already tried phoning the hotel). I don't want your standard simple skeleton type key but that is all I can find after searching on the internet. As you can see in the photo, this one is very intricate. Any ideas?

THANKYOU SO MUCH!
