Bump key experiments


[Barry] took one of his blog readers comments to heart and started wondering just what happens when you bump a lock. As suggested, he made a cut away lock core and started experimenting. [Barry] doesn’t have a high speed camera, so he tried some alternatives like filling the chambers with grease to indicate pin movement. Master Lock put together a nice video demo of lock bumping (in order to sell their new bump stop gear).

Open an AXA bike lock with a blank key (Doh)


[Barry] sent in his writeup and video about a serious vulnerability in the AXA bike lock. (One of the most popular locks in the Netherlands.) It turns out that quite a few of them can be opened with a blank key. [Barry] demo’s the hack, and has some comments about the lame efforts of the manufacturer.
