Yes that's exactly what happened. I was one of the largest Kryptonite distributors for many years, and was very dissapointed when they changed to this IMO lousy keyway system. See if you can line up the discs and get the key all the way in, then work it all the way to the right and back all the way to the left and see if that aligned the discs so you can withdraw it. Otherwise, bring it back to where you bought it and let them deal with this BS.
