Can you make a bump key?

Step 1 Make the Bump Key A bump key is made by using a triangular file (they're at every hardware store… very cheap) on the blank key. If you don't want to use a blank key, you can just use one of your spare house keys.

Today's Null Byte is 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. 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 an exact height 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.

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.

Step 1 Make the Bump Key

Go to the any store that has blank keys. Wal-Mart and Home Depot have them. They look like this, without teeth at all: A bump key is made by using a triangular 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.

Step 2 Bump 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.

3 Other Uses of Sugar Wax You Didn’t Know About by Sugar Coated

Exfoliates the Skin

Sugar waxing doubles up a gentle exfoliant. Sugar waxes stick to the hair and dead skin cells. Removing the strip picks up those dead skin cells and exfoliates the skin. This is part of the reason why sugar waxing leaves the skin feeling so smooth. Unlike waxing, there is no need to exfoliate before sugar waxing.

Food for Bees (Well... this one is just for Sugar Coated)

Diluted pure sugar syrup is a great alternative source of food for bees when they are unable to get enough nectar in colder months. This is only used as a special measure by beekeepers when certain hives need a little boost. Sugar Coated sugar syrup is the only sugar wax that is suitable for this as we only use pure sugar syrup with nothing else in it. We donate a portion of our sugar syrup to local beekeepers to help their hives. We donate straight to the apiary manager so they can use their expertise to manage when to use it. Sugar Coated sugar wax is 100% natural, registered as vegan by The Vegan Society, Leaping Bunny approved as cruelty free. It is eco friendly and has 100% recyclable packaging.
