Questions on blanks for bumping.

by **Bibble** » 30 Mar 2007 23:04

i've got a question that i haven't been able to figure out.
I've been a lock picking/bumping enthusiast for a while on and off, and i've recently gained access to a number of locks and blank keys. (i work at the hardware store, and we cut keys)

If i don't have a key to work off of to make a bump key and i only have a blank, how to i cut the key to the shape of a bumpkey so it works? do i just cut them at equal intervals?

Are you planning to cut them at work?

this post seems kinda suspect to me, although you do seem to have a "basic" knowledge of the questions u are asking it seems odd for a "picking/bumping enthusiast" to ask how to make a bump key.

I suggest buy one or have a search around the site. all the questions are answered and as an enthusiast you will know the terminology to be able to find the information you need.

I do not mean to offend but as a fellow enthusiast you will appreciate that we must act with some caution to such questions.

All the best

Do you not have depth/space keys at work?

Im not sure how things are in the USA but most DIY/hardware stores in the UK can only trace key not cut them from code. If you want a code cut key u have to go to a locksmith.

Does it not work like that there?

I believe you are correct.

by **Bibble** » 31 Mar 2007 2:32

correct.
we can't cut keys at work unless we have something to copy them from, and all the bump keys i've made are from the miscuts that don't work, and i've filed them down myself.

I know how bumping and picking works, and i've bumped a few locks, but i have never made a bumpkey from a straigt blank.

I've used the method where i mark the center of the "valleys" in the key, and file them down that way by hand.

I only get the blanks and locks from work, i don't actually cut out the keys there.

Reading over my post i can definately see how it could be suspect.
I should have elaborated more. But yeah. No offense taken. I can see where you're coming from.

You can get the depth and spacing for a particular lock and try to work from there or you can get a bunch of different keys for a certain model and copy all off them on the same keyblank.

I have cut keys in hardware stores, I know most of the machines used by the major Home Depots, Lowes, and Walmarts on the East Coast, and I know you would get fired from your job for making one of these things. I will admit that I made a few from some miscuts, but once I figured out I could make them with ease, they bored me. That's why I'm on this forum. I also think lock bumping should be restricted to the advanced sections of the forum, no matter how much other information is on the net. Bumping is not picking and takes no skill.

If that comes across as harsh, I'm sorry, I'm not dumping on you, but I hate to see people trying to take a short-cut to solving puzzles. It's like saying you're a musician because you have a CD, but you never listen to anything else or learn to play yourself.

This has been discussed to death here and it appears this type of info will stay in the public forums.

Bibble, my first bumpkey was made with a duplicator. I cut a copy of a key then I just eyed the cutting wheel straight into the cuts on the copy. guessing on the depth. Then I just took a file to it and kind of finished it up. This key is still one of my best working keys and I've often wondered if it's because the valleys are not as wide as a normal key.

I assume the main reason is because there so much of it on here. it would take days to get them all moved or delete.

If the valleys are steeper then i guess it would make the pins just more?

Bible, are you in the UK? at least put a country in your profile so we can help on your questions,

We dont need more bum key threads but as its a question not often addressed im willing to help out a bit if i can,

As for spacing please look up the impressioning threads,

A simple way would be to run a marker over the blade edge or use the soot off a candle,

Insert the key to the lock and twist it both ways putting a little force on both directions,

Remove the key, if its clear where the pins have marked this is your spacing, if it isnt clear put it back into the lock and turn to one side and wiggle the key up and down whislt putting turning pressure on, do this the opposite direction as well and then look for your marks,

As regards depth with nothing to compare it to you can only guess but guess may be made better if you measure the plug diameter and divide it by 2.5, remove that from the top of the key for a starting point,

I only asked about the D&S keys because many of the local hardware stores I've seen are far better equiped than a Walmart of Home Despot.

Nah, in the uk they have claped out duplicators only,

The locksmith shops tend to have code cutters,

From my point of view its the mobile lockies with a duplicator in the van that use S+D keys,
