Wow, what an insecure "lock"!
I'm not certain, but I think the lockers at school might have used a similar system. We are going back the late 80's, but I have vague memories of some of the kids being able to open the lockers of others, and of the key being able to turn around inside the lock even when only partially inserted. At the time I had no special interest in locks so didn't pay great attention to the mechanism and action.
The keys themselves only had the notches on one side though - however I can't see a reason why you couldn't make a warded lock with the wards on only one side. Can anyone with more knowledge confirm this?
The key was just a flat piece of metal that looked something like this...

P.S. They didn't teach me ASCII art at school, so I'm self-taught
