While in vacation in Rome, I stayed in a newly constructed "bed and breakfast" otherwise known as someones rented condo. Now, the condo was through a key-coded gate, key-passed building entry, and finally, the focus of my inquiry, the vault like front door.
I believe the key was a dimple type. It took 3 half-rotations of the key to retract all of the door pins (540 degrees). I know there were 4 door pins where the latch/receiver would be, at least 2 hinge pins, and 2 more pins on the top of the door.
So...does anyone know where I can get a door mechanism/lock like this? A name, anything similar?
As far as hobbies go, I have too many

P.S. the condo was not in a dangerous area to my knowledge
