This doorlock from 1680 has lots of cool security features

The engraving on the works is beautiful, and the key even more so. What a gorgeously intricate thing!


“1680”. Someone trying to bust in likely wouldn’t have been able to read the inscription. Otherwise, that someone would have said, “Whoa! Message received! I’d better just turn right around and skeedaddle!”



An excellent example of security through obscurity. Few people that saw this lock would know how to operate it, even now. (

Reminds me of the security door to the Reptile Room in the recent adaptation of A Series of Unfortunate Events. ("…or just turn this doorknob.")


The key is striking, really

Most mechanical locks work that way. I have a transparent padlock I bought on ebay. It came with lock picks and once you get the trick, its easy to see how most similar locks could be opened.

You have misunderstood how it works. The hat trick only unlocked the latch not the bolt.

The key is required to lock and unlock the bolt.

Granted, picking that lock would not be that hard if you had the correct tools.

This lock was described in the 1727 treatise “Locked mechanism difcovered in the back of a closet in manor house”.


I’m imagining the owner of the lock excitedly showing it off to his servants. One hundred times, you say?
