Don’t Use “U-Lock” Bike Locks
I ran across this article on Wired that actually shows how you can open a supposedly unbreakable lock with a ballpoint pen. Having owned one of these locks in the past, it was quite a shock to see. According to the article, all you do is take the tube of the pin, cut four small slits in the top of it, and shove the tube into the lock’s cylindrical lock hole and twist. This news story has been spreading around news groups all over the Internet and surely every criminal in the country will know this knowledge soon.
I recommend taking a look at the article yourself and then go to your bike shop and get a lock not based on the “axial pin tumbler” locking mechanism. A strong chain with a combination lock would even be better, even though chains are pretty easy to cut. The vulnerable type of locks are also used for locking down laptops so you should replace those as well.
