I was a little skeptical, so I followed the link trail to the actual paper:

They did not take a recording of an actual key in an actual lock and determine the shape of the key. Instead they simulated the sound of a key in a lock, and determined the shape of the key from that simulated sound. And the simulation assumed that the speed that the key moves at is fixed as it enters the lock, at 1 inch per second.

So this article is false. It wouldn't have been that hard to read the paper, and say what they actually did. It bothers me that articles like this don't, and instead run with an exaggeration.

EDIT: As far as I can tell from the paper, at least. What on earth is a "simulation, based on real-world recordings"? I don't see anything about an actual recording in section 4.

Dug out a link to the orginal research paper (mainly because I was a bit skeptical of the claims)
