Review on Kryptonite Kryptolok Folding Bike Lock by Alfredo Nosrac

I've just purchased this great Kryptonite Kryptolok bike lock which has had great reviews. However, it was an open box primarily sold by AMAZON.LLC. . Who would have thought Revane would screw it up. The keys that were in the box did not open the lock. They went with some other castle. If you're buying an open box, what you think might not be great. A lock without a key turns into big, heavy paper. Of course I sent it back, but what a hassle.
