Interesting. Completely mechanical, so no batteries and no need for a key. They appear to be a bit more complicated to install than the regular electronic ones, but still, very interesting.

Thanks

I suppose I should have been aware, but the truth is I've never really thought much about different locks. When I had a new front door installed, they put in a deadbolt, and I never gave it a second thought.
