Bicycle Lock Warning
Apologies if this has been posted already, but I just read about it
and thought I would pass it along. Reportedly some versions of Kryponite locks are easily unlocked with a bic pen empty pen. http://www.nytimes.com/2004/09/17/ny...ock.html?8hpib Regards |

I have a Specialized 5/8 inch cable lock with a circle key. The barrel is too large for a BIC pen to fit, even after trying to ream the BIC pen tube. However, other plastic tubing is available. Could the Specialized lock be picked with larger diameter plastic tubing. -- Cheers!

I have a Specialized 5/8 inch cable lock with a circle key. The barrel is too large for a BIC pen to fit, even after trying to ream the BIC pen tube. However, other plastic tubing is available. Could the Specialized lock be picked with larger diameter plastic tubing. Maybe. There are other factors which are also relevant to the issue; most important, if the center post of the lock cylinder assembly is fixed and non-rotating, the penning trick fails. Part of what makes the penning method succeed is the fact that the Bic pen body must stretch to fit the center post, which allows it to grab that post and put torque on it to make the attack function. If the post doesn't rotate to operate the lock, then the conditions that allow the attack to work are not present. Cable locks, though, are easily cut, so a thief with a cutter is unlikely to waste time trying to pick it anyway. That cable will stop a cutter for all of about two seconds. It can take several minutes to pen a lock; thieves like to take the stuff that can be immediately put in grab-and-go condition with the tools they have at hand. I wouldn't trust a cable lock to keep a bike from being stolen. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts. |
