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!

I have quite large rimlocks that use a key like that. Brass plated, multiple round bolts (shooting one direction). Principally designed for gates and having double or triple throw they are not necesarily as secure as other locks because they are rim locks with normal fixings to the door. Were you going to put it on your front door and do you have insurance requirements?

This is a Deny key:
Check their web site (in French though)

This is an old thread, but for anyone searching, there is coverage of the Deny lock in PULFORD, G High security mechanical locks pp414-5.
This is a lever cylinder mechanism derived from the Davis lock of 1799 UK2306, containing both wards and levers. Many key steps are redundant, but the lock despite not being high security is useful for its weather-resistance.
The company was founded by Charles Dény, and operates in Picardy.

This lock is not like the Italian-style doublebit locks also seen in Europe and elsewhere.
