Now they use the flat keys and Kryptonite locks are now having reports of the key snapping inside the lock making the whole thing useless.
Yep, the discs of those springless disc detainer locks can naturally float and rattle out of alignment and the user has to thread the key in carefully and make sure it's all the way home before torquing it. Also, always use the weather cover over the keyway and
lubricate the lock every now and then.
