That's kinda funny that they've gone through the trouble of putting spoorated drivers in the lock, only to color-code the key pins... which means that anyone who's seen another brinks kit like that can decode the lock bitting by sight. Worse yet, if you've combinated that lock to match your house, they now have a key to your house too!
Then again, if you have a KW1 on your door to begin with, it's probably takes less time to pick than it does to decode the lock

Still, those are cool little kits, it's just a shame that the tradeoff in making it easy for the customer to use is that it becomes pretty easy to decode the lock.
