How to Create a Bump Key to Open Any Door « Null Byte :: WonderHowTo

Lockpicking is a skill that takes years upon years to master. Locks come in all sorts of shapes and sizes, but have common ground in how they work. Most cylinder locks have "tumblers," which are metallic cylindrical objects that sit vertically to the actual locking mechanism. Tumblers have five or six holes with rounded key pins of various height in them, each needing to meet anexactheight or the cylinder in the center (the lock itself) will not be allowed to turn. This is the reason why you see those "mountains and valleys" on keys, and why these types of locks are called pin tumbler locks. Each is unique.Today'sNull Byteis going to demonstrate how to effectively make what is called a "bump key". A bump key can open any lock that it fits into. It's helpful to have in your pocket if you ever lose your keys, because it can open your door lock and your deadbolt, even if they normally require seperate keys. I keep mine in my wallet.What Makes It Work?The teeth in a bump key are set really low so that you can fit it into locks where the tumblers may be set as low as possible. The teeth are steep and jagged because when you "bump" the key while applying torque, for a split-second, all of the tumblers will bounce up into their perfect positions allowing a window for you to open the lock. The torque you apply makes the tumblers stop once they reach the desired height.Please don't use this key to go into places where you do not belong.Step1Make the Bump KeyGo to the any store that has blank keys.Wal-MartandHome Depothave them. They look like this, without teeth at all:A bump key is made by using atriangular file(they're at every hardware store… very cheap) on the blank key.Point the file down to shave the extreme "valleys" that you see in a bump key, with ample force. Use it to shave down the grooves on the key to look like this:If you don't want to use a blank key, you can just use one of your spare house keys.Step2Bump Open a Lock!Put the key into a hole at the end of the plug (exactly how you would normally open a lock). The bump key pictured above would fit into most cylinder locks and deadbolts.After it's pushed all the way into the lock, pull the key out until you feel it click twice.Take your blunt object (I use a pocket knife) and hit the key with a bit of force, while applying torque (pressure) to turn the key in the direction you need to in order to open it.It's a little hard to get at first, but once you get the feel for it, you can open it the first try nearly every time. Here's a video demonstration on how I used one to open my garage.Please enable JavaScript to watch this video.Good job making your first bump key! Talk with me one-on-one at ourIRCchannel!
