I'm guessing that a number of his customers must have been asking: he's updated the description on his more recent auctions:

These are Bump keys everyone is asking about . . . These are cut to Factory Specifications you modifiy the TIP and or SHOULDERS yourself . . . I don't know how these are used . . .

I think he may be pushing the eBay rules a bit now... the additional instructions weaken his "I don't know how these are used" claim a bit. :wink:

Ehh either way, let the man make some cash to feedhis family.. or get drunk either way.

Now if a tomahawk appears int he auction to then i say its a little over board :wink:

Here is a rather poor photo of the space and depth keys that the vendor mentioned in the first post is selling

He includes Schlage, Yale, Westlock, Weiser and Kwicklock. all cut by code to the deepest cut for that blank.

Just to remind folks...... in of them selves these keys won't bump locks, until the shoulders and tips are ground down a bit.

I grabbed a set since I've been on an eBay spree lately and the price seemed fair to me. I've wanted to try bumping for some time now but can't be arsed to sit there and try and file a key blank down to the required bitting by eye. I'd rather file out a shiny new pick if I'm spending that much time...

Whenever I feel the need to bump one of my locks I'll just take the correct one of these babies over to the local convenience store and have a couple of working copies run off, so I can do the required modifications while keeping the master version unmolested. I guarantee that there is no way the nice old lady there knows what a "bump key" is either. :twisted:

Well if oyu already have the key its no biggier, just pop in push the button and bang there it is.

Its asking for themt o cut one by code or specifing its gets a little sketchy.. or jsut go to lowes like i did

That's why this guy's auction is a godsend... Anywhere around here that can cut to code would be an actual locksmith shop and would know about bumping (and probably tell me to take a hike). With a set of pre-cut bumpkeys I can go to any mom'n'pop mini mart or hardware store and they'll just run off as many copies as I need (and probably have no clue as to their true purpose).

The first is a schlage. My home key is a schlage and has the same design (except for the teeth).

Yeah, you know this guy knows what he's selling...just using wording to cover himself, LOL, but hey, I'm liking it and may pick up a set, LOL.

Pickmonger, can you modify the picture you sent to show how the shoulder and tip should be modified? Cool topic!

by **!*AMP*!** » 4 Aug 2006 13:57

um, I understand how bumping works, and have gotten a set of bumpkeys, but was also wondering what type of modification has to be done. I'm assuming it's that the shoulder and tips that have to be shortened to make better, smoother contact with the pins? Thanks guys...and yes, I joined before the MSNBC story, and actually never even saw the story. Thanks.

by **!*AMP*!** » 4 Aug 2006 13:58

Doh, I wish there was a freakin edit button...guess I should read the thread LOL

So, should I file them down a bit until smoother contact is made? Or am I deburring the key? Thanks.

No. When you isert an unmodded bump key into the lock fully, what happens when you hit it? Yup, absolutely nothing. In order for the key to move inside the lock a bit more, you need to file a bit oof the shoulder, and off the tip, this lets it get further in the lock than should be possible.

The alternative technique is to merely pul the key out one space and then bump like that, but it's less effective.

by **!*AMP*!** » 4 Aug 2006 14:12

Oh, I understand what your saying man...after watching an animation of how bumping works, I understand that what you said makes sense...it has to be able to go past the pins just slightly, if I see this right, so that it can release the pressure front he key into the pins, um, am I right? Thanks man.

by **illusion** » 4 Aug 2006 14:16

The peaks of the key have to bash into the pins, and this causes the pins to seperate, due to a phenomenon I'm sure you already know about. If the key is not aloud to enter the keyway a bit after it has been bumped, then you merely make nice little dents on the plug of the lock, but little esle happens.

by **!*AMP*!** » 4 Aug 2006 14:33

I wonder if police in the US will start seeing more dented doorknobs on botched robberies since the MSNBC story, LOL
