Kensington Laptop Locks Not So Secure

eric434 writes "According to a security alert released by Security.Org, the Kensington laptop lock that many of us use and love isn't secure. In fact, it can be opened in 30 seconds after about a minute of practice with a $1 worth of equipment. (A Bic pen, and a pair of scissors. In the interest of giving people some time to stop using the locks, the actual method of opening the lock is left up to the reader.) To make matters worse, Kensington's 'We'll give you $1500 if someone steals your laptop' guarantee doesn't apply -- because the process of opening the lock doesn't damage the lock or cable." Mind the source, though -- security.org wouldn't mind selling you a book on locks and safes.

    We'll give you $1500 if someone steals your laptop' guarantee doesn't apply -- because the process of opening the lock doesn't damage the lock or cable.

    After your lock has been cleanly picked, go to your local Home Depot, get a cable cutter and cut the cable yourself. Make sure you make a real mess of it. Then send back to Kensington and claim the $1500.

      It is fraud on Kensigton's part that they claim they have cable that is secure, yet is easily pickable.

    Trunk of your car is better than nothing in Chicago, though, and certainly better than the front seat. As long as they don't know there's anything in the trunk, they're less likely to hit your car.

    Especially if you drive a beater that looks like it couldn't possibly have anything valuable in it, and leave it in a good neighborhood with lots of Jettas and SUVs and expensive crap. (coughLincolnParkcough).

    On the other hand, I've sat with the owners and watched their 300k mile, damn near dead, Chevy Nova get stolen from in front of their house. I mean, they wanted it to be stolen, since getting it towed (there were brake problems to the point that they didn't want to drive it, not safe) would have cost as much as a junkyard would have given them, but still, its kinda funny to sit with someone who's *watching* their car get stolen. I love Chicago.

    Instead of locking the laptop to a desk or table, loop the cable around a body part - preferably a body part where constriction will not kill you (neck = bad, waist=good). When you stand up to walk away, the laptop will be dragged along with you.

    This also serves as a work-around for many short term memeory disorders - answering once and for all the age old question of: crickey, where did I leave my laptop?

    Jam one point of the scissors into the rectangular hole on the circumference of the circular key slot. Twist the scissors so that the inner part of the lock turns into the 'open' direction. Keep applying a gentle pressure, and use the paperclip to push in the little pins in the circular groove, one by one. Push down lightly and slowly until you feel the pin 'snap'. If you release the pin, it should be held in place and not spring back up again. If it does, just try first with another pin. Eventually you'll get them all and the lock will turn open.

    That just sounds like normal lock-picking to me. Here is an article on the technique that is describing pretty much the same thing on a more traditional yale-style key.

    Great. I've just taught serveral thousand geeks how to lock-pick... ;-)
