Are you familiar with lock bumping?

  1. What is lock bumping? Up until it was explained to me by my new buddy Martin McKeay, I also had no idea what it is.

    Taken from its very own Wikipedia page:
    There are a number of videos available highlighting the technique of lock bumping, including on YouTube:

    YouTube video #1
    YouTube video #2

    Do a quick YouTube or Google search, and you'll likely be amazed! :eek:

    I'm not sure its such a good idea sharing this information with everyone, but its an interesting thing I've not even heard about. I have some info on lockpicking using picks, but this seems so much easier.... however you need that darn bump key specific to the lock, which may be a little hard to obtain.

    Yes. I made a key myself, problem is I couldn't make it work. I thought I did a pretty good job making it too, so either I'm missing something obvious, or it isn't nearly as simple as all these videos showing how easy it is seem to make it.

    yeah I think those videos are kinda like the "how to repair a scratched CD with a Banana" one on YouTube. Something is a miss somewhere....

    maybe for a $1.95 diy lock kit, but any good lock would not behave this way.

    That's what I thought, then I saw someone do it in person... :eek:

    If you google for 'whatthebump' (I think its wmv but it might be avi) there is a long video from defcon or something similar from a few years back that talks about it.

    Supposedly it works better on more expensive locks because they have tighter controls and the pins then can be struck and move correctly, where cheaper locks the pins might not go straight up and could loose momentum by hitting the walls.

    Perhaps in that same video or another they had a comment about how some ugly looking (poorly filed) bumpkeys worked just as well as nicely made ones. I thought I did a fair job on mine, certainly not perfect, but not bad either and I had no luck.
