Lock
Until 2004, Kryptonite locks used the tubular pin tumbler locking mechanism. Videos circulating on the Internet demonstrated that some tubular pin tumbler locks of the diameter used on Kryptonite locks could be easily opened with the shaft of an inexpensive Bic ballpoint pen of matching diameter.
In 2005, Kryptonite changed their locks from a tubular-key to an I-key, which stopped the ability of a BIC pen or other cylinder shaped object from defeating the locking system.
