Posted by LogiGoi on 07 January 2016 - 12:52 PM

Using bump keys doesn't require a profession...it is already by default that locksmiths are the ones making it after all it was their job and skills that put the bump keys into existence...whatever your profession is, you can use a bump key,...just don't make using bump key to other people's door lock your profession...

#6970 Bump Keys vs Locks

Posted by redcity on 02 January 2014 - 06:27 PM

I would say that the biggest part of locks can be opened using bump keys except for the very expensive ones made for special buildings they would have deadbolts and trap pins. Search for non-bumpable locks if you are willing to buy one and yes they are certainly safer.

#4622 History Of Lock Bumping

Posted by Customer Support on 20 April 2008 - 12:57 AM

History of Lock Bumping

How did the fascinating technique of lock bumping get its start? When did this lock bypass system begin to come to the attention of the public? What’s that, anyway? Let’s explore the interesting history of lock bumping and look at a few important details pertaining to it.

Lock bumping has been around for a long time. Some estimates place the beginnings of lock bumping to about 50 years ago. This special technique allows a special type of key to be used in any lock of the same type. Most of the locks that are currently being manufactured are susceptible to the skilled use of a bump key.

Tumbler locks are the most widespread style of lock in use today. The system of pins is quite simple. A series of pins are spring-stacked to hold the rotating bolt of the lock mechanism in place. Because the pins are all different lengths, one usually uses a custom cut key to open the lock. The grooves on the key “tickle” the pins and lift them out of the way enough to let the bolt slide away, resulting in an unlocked door. However, a bump key can do the same job even though all its grooves are the same depth.

Public knowledge of lock bumping really began in the 1970’s, when Danish locksmiths distributed a method for bypassing the tumbler lock mechanism. They would tap on the side of the cylinder and simultaneously press the lock plug (in our case, one would press the back of the bump key). The vibration would cause the pins to become loose; once this happened, the lock plug could be removed easily.

The advent of bump keys came much later. Surprisingly, they were not even considered a security problem until 2002 or 2003. The German media was the first to pick up on the possible hazards of lock bumping keys. Other organizations published carefully considered reports on the uses, techniques, and hazards of lock bumping. Papers have also been written about the possible legal problems connected with bump key usage. Although in many States a bump key is considered by law to be a “burglary tool”, this is no reason to avoid them. This law is not going to harm you as long as you use the bump key for legitimate purposes. Currently, there must be proof that there was intent to use the bump key in a burglary before you can be charged with anything.

Lock bumping can be a beneficial skill. It is an easy way to get back in if you are locked out of your home or office. You can make a bump key for free with a simple file, and it takes minimal training to learn how to use it. Don’t ever go through the frustration of being locked out of your own home (or your own personal safe) again. Learn how to use a bump key and practice until you know you can get past the tumbler locks in your home. One day, you’ll be glad you did.

Good reviews like this really help. Specially from forums. It will help those who are just planning to buy as they can directly ask how a certain product like bump keys work for them. 

You can also have trust in the website if there are many people who are giving positive feed backs...at least before you decide whether to buy or not, it's much better to review some feed backs...better safe than sorry... ;)

#7723 Easiest way to make your own Bump Key

Posted by xcaliber on 12 December 2015 - 10:52 PM

Utilizing these qualities, you'll make your first cut utilizing the first esteem (key shoulder to first cut), then each resulting cut will be separated at equivalent interim utilizing the second esteem (separation between focuses). When in doubt, you slice to the indented line on the clear key. Then again, for more prominent exactness and enhanced adequacy of your home-made knock key, you'll most likely additionally need to decide the cut profundity, which is an exact estimation from the base of a slice to the base of the key (this data ought to likewise be given in your lock maker's profundity and separating aide). In the event that you don't have a precise cut profundity, you can for the most part slice to the indented line (never beneath!) and your key will likely work in many lakes.


It is essential that you ensure that the valleys in your key, don't go beneath the indented line on the key, furthermore, that the point of your slices are sufficiently shallow to permit smooth insertion and expulsion of your knock key from your objective lock. On the off chance that the valleys are too profound, you knock key will presumably not work. In the event that your values are excessively steep, you may harm the lock or you will be unable to expel the key from the lock once you've knocked it! Our expert knock keys are sliced by producer's predefined cut profundity with progressive valleys and tender crests.


Finally, once you've created all of the necessary peaks and valleys in your new bump key, you'll want to file a small bit off the tip and shoulder of the key (generally <= 1/2mm will suffice).

Smart Ass Answer #2:

A truck driver was driving along on the freeway. A sign comes up that reads, "Low Bridge Ahead." Before he knows it, the bridge is right ahead of him and he gets stuck under the bridge. Cars are backed up for miles.

Finally, a police car comes up. The cop gets out of his car and walks to the truck driver, puts his hands on his hips and says, "Got stuck, huh?"

The truck driver says, "No, I was delivering this bridge and ran out of gas."

"Now class, I won't tolerate any excuses for you not being here tomorrow. I might consider a nuclear attack or a serious personal injury or illness, or a death in your immediate family, but that's it, noother excuses whatsoever!"

A smart ass guy in the back of the room raised his hand and asked, "What would you say if tomorrow I said I was suffering from complete and utter sexual exhaustion?"

The entire class is reduced to laughter and snickering. When silence was restored, the teacher smiled knowingly at the student, shaking her head and sweetly said "Well, I guess you'd have to write the exam with your other hand."

Some pics of the keys would help. Preferrably both sides and an end shot so we can see the shape of the keyway.

Taking clear closeup pics of anything is difficult without professional camera gear, but I've found a large magnifying glass, like those found in some swing-arm lamps placed between the key and digital camera really helps. Also plenty of ambient light and no flash usually helps.

#2752 A Master padlock and homemade M1 bump key

Posted by theopratr on 29 March 2007 - 07:17 PM

People are pretty split on what lock to start on. I started on a Kwikset, so I'm rather biased. Many people start with Masters to go on to long, happy bumping careers, so to start with a Master lock, I gather, is not a terrible thing.

As for your key... not a bad attempt at all. Your self-analysis was largely correct. The spacing is sufficiently off such that the key will never work. The peaks were a bit large, but that could have been fixed. Get yourself another blank and try it again. Take an existing key (regular key, not a bump key) and mark on your blank the relative horizontal positions of the grooves, and file those down first. Once your grooves are all set, then go about making your peaks into nice little triangles. This way, you'll be guaranteed a key that can be made to work.

On the key that you made, the quality looked great. You mentioned that your grooves should be flatter... and although machine cut keys do have nice, flat grooves, you don't necessarily need them. It just makes the key look better, but as long as the cut is wide enough to let the whole pin rest at a point that is below the deepest cut for that particular keyway, you're good, whether or not the groove surface is flat. The angles on your peaks looked great, and the key has a nice sense of uniformity on it. If you mind your separation intervals between grooves, your next key should work like a charm.

I know I just posted, but my explanation was a bit sketchy. This diagram should clear it up a bit. Best of luck.
