The rotating plate lock mechanisms are identical on my 2005 OnGuard Brute and on my Kryptonite New York 3000. They share a "pick resistant" design that makes opening the locks with any sort of picking tool much more difficult.

The rotating plate design works perfectly IF, but only if, owners follow the instructions provided by OnGuard and Kryptonite: insert the key fully so it is seated at the bottom of the key mechanism before beginning to turn the key. If an owner ignores the instructions, and turns the key before it is seated, the lock will not open. That is the "trick" that makes picking these locks so difficult.

If someone accidently rotates the plates and the lock jams, it takes only a few seconds to use the tip of the key to realign the plates, fully seat the key, and open the lock.

The problem here is not with the locks. It is a "defective owner" problem. Most guys consider it unmanly to read the directions that come with a product, just as it is unmanly to read a roadmap when lost out on the road. If a fella can't figure out how these new "flat key" locks work, he can have his wife read the instruction sheet and then explain it to him.
