Kryptonite abandoned cylindrical key locks all together and now use a flat key lock that is harder to pick. The whole BIC pen cap thing took everyone, including the lock manufacturers by surprise as Cylindrical locks were considered higher security back then. But I suspect that if you just give it some time, the scummy theives will always find new ways to pick the newest lock designs too. It's just a technology war that keeps going on and on between the lock makers and the bad guys. Unfortunately, the bad guys keep figuring out simple "McGuyver" types of solutions that gets overlooked by so called lock "engineers". The BIC pen cap was an inexcusable mess up by the lock makers IMO. At least, Kryptonite offered a nationwide lock exchange program. They replaced two locks for my motorcycle (A brake disc lock and a large "New YorK' U lock) with the program without any cost to me, but I don't think the other manufacturers were as nice about it.
