I have a kryptonite evolution mini U-lock with the new laser-cut style keys that is about a year old now. A few days ago the key got stuck in the lock while I was locking up outside and now it won't come out at all. I can still use the key to lock and unlock, but it won't come out no matter how I turn or jiggle it. Have any of you come across this problem before, or know of a solution? (short of sending it off to kryptonite for replacement) Thanks!
