The Next Phase of Bumping - 'Spring-Bumping'

[lockey1963]

i prefer the hot glue , same method but no marking or damage to cylinder, though only use bumping as an entry method for ISEO R6 locks and Azbe 6 pin dimple locks.

I don't see the point, honestly. With a small bit cut off the shoulder, the spring pressure on the pins will kick the key back automatically. If that's not happening for you already, you've got too much off the shoulder.

I never have to "reset" my bump keys unless they're old and beat and the shoulder is banged away to much.

I agree, but the spring method could be an improvement to the pull out method. Not that it's necessary to use the pull out method, but it gives another option to bumping.

I honestly don't see any real advantage to using a spring to "reset" the bumpkey. It really seems like an annoyance.
Plus if it were to be used on a lock that is older/dirty you'd still have to pull out on the key to reset it.

hot glue and rubber bumpers have also been tried, if using rubber bumpers, you put a fender washer (wide flange washer) on the key firstso that the bump does not tend to cut where only the edge of key is being driven into it. with a shorter spring, one could put the washer on and the spring on then apply the hot glue into the spring,
No idea should be dismissed without trying it out.
There is a tendency in the forums to dismiss what has not been explored fully firtst. this is intellectually shabby.

Here's one of our keys, the tip is always the first peak and you'll see how much we modify the shoulder. This also helps for 'swing and clip' bumping, a UK bump keys technique like planishing, where you swing the bump-hammer in an arc and catch it on the way down.


Try it

just out of curiousity.... what's to keep that from working as a -reverse- bump key?

i.e. you allow the spring to snap the key out of the lock, and apply the twizt as it comes out? with a lowerprofile ramp (say 9-8 only) overremoval won't bounce the pins more.....

I do now see how this modification improves the quality of a bump key really. What I do see is how it decreases the wear a bump key can cause a lock. Seems like a less time consuming alternative to hot glue.

Well done.

I dont see how this modified bump key any different than the original one aside from having it pull out faster? Ive seen regular bump keys open locks easier than the one in the video.

Seems interesting, but kinda pointless.

For the lazy rich people. They don't have to take the key out, and because they can spend money all extra keys!

I can see this idea implemented into some kind of automatic bumping devise. Something that would look as professional as a pick gun when used by a locksmith.

I tried something like this, I riveted a flat spring to the side of the key. It worked as a bump key but I preferred to bump without the spring. The benefit of the spring was there was not any impact marks on the face of the lock from the shoulder of the key

I think the question for the OP is why is this addition necessary?

Bump keys alone seem to work fine
