Bump Key

Bump Key

How is a bump key used, how does it work, is it new, and what are its limitations?

A bump key is a specially designed key that is used with a hammer or other item that applies blunt force to open a lock. These keys are usually used on a standard pin tumbler lock. While this sounds alarming as if it makes locks useless in protecting your property and keeping your family safe, there are limitations in what locks a bump key can open.

 

How a standard pin tumbler works

The basic parts of the lock include a key pin, a driver pin, a shear line, a cylinder, the plug, and the bible. The bible houses the plug, cylinder. The key is inserted into the cylinder. For a lock to open, it requires the use of the correct key. When a key is cut to fit a specific lock, the grooves are what allow the pins to line up properly with the shear line in order to turn the key and unlock the lock by turning the tumbler. The basic pin tumbler lock uses several stacks of pins. Each stack contains a bottom pin which is the key pin, a top pin which is the driver pin and a spring that is located above the top pin. The key pins are of varying lengths, while the driver pins are usually a standard length.

Using a bump key requires both skill and a bit of chance. A bump key is cut using the same brand of key as the lock. The grooves on the key are carefully filed down. The trick behind a bump key is that it moves the pins to either side of the shear line for just a quick amount of time that allows a blunt force, bump, to line up the driver pins above the shear line with the key pins below and allow the tumbler to turn.

 

Are Bump Keys New Technology?

Bump keys, or methods of picking a lock, have been around since the invention of the key and lock hundreds of years ago. The easiest keys to turn into a bump key are those that have a bow, the head of the key, a tip, the part that is inserted into the lock, cuts or grooves, and a shoulder, the part that rests against the edge of the outside of the lock to stop the key from going further into the keyhole when inserted. Years ago, locksmiths introduced a technique that was used to correct a cylinder that had been assembled improperly in their workshops and not as a way to break into a home. This technique involved tapping on a lock cylinder while applying pressure to make the pins jump inside the cylinder making the plug slide out freely.

Bump Key Limitations

Because almost all of residential doors in the United States use cylinder locks that are so vulnerable to bumping that a child could do it, they are an easy target for criminals. However, there are some limitations and show visible signs of forced entry when the lock is examined. A bump key will not work on high-security locking systems or on automobiles because vehicles do not use a pin tumbler style of lock but rather usually use sliders or wafer locks. However, there is a jiggle key that is somewhat similar to bumping.

 

How Do I Bump Proof My Locks?

First, take steps to securing your property by taking part in neighborhood watch programs, keeping landscaping trimmed so criminals may not hide as they try to gain access, and use security cameras and alarm systems.

You could also install an anti-lock bumping device that prevents the turn knob that locks and unlocks the lock from turning, install security pins or high-security locks or a keyless entry system.

Lock Picking – Information and History

When you are locked out of your home, office, or vehicle, the skill of lock picking begins to look very appealing even though it is often connected with would-be crooks to break in and steal. When it is your own property you need to access, lock picking is sometimes the only way to get back inside. There are some do-it-yourself tricks to try, but when you want to gain access to your own space and need to get inside quickly without leaving damage to your locks, it’s time to contact a local professional who will arrive quickly to get the job done right the first time with the proper tools, training and technology to open your locks and duplicate your key on the spot.

 

It is helpful to understand the history of lock picking. The locksmith profession dates back to the 1770s when an inventory by the name of Joseph Bramah came up with the technology and skill to do so. It began with a lock he created known as the Bramah safety lock the consisted of complex layers between the key and the deadbolt. In 1777, he issued a challenge to anyone who could come up with a device that could pick the lock. The challenge included a cash reward. Around the same time, a man named Jeremiah Chubb met the challenge of the British government who asked for a lock that would alert you if there was an attempting break in. Chubb and Bramah were the names of perfect security locks until 1851.

In 1851, at the Great Exhibition in London, an American locksmith named A. C. Hobbs demonstrated that he could pick the Chubb lock and did so in less than a half an hour. Not only did he pick the Chubb lock, but he met the lock picking challenge that Bramah had issued 70 years prior. His ability to pick both locks left lock buyers questioning whether perfect security would ever exist again. However, a locksmith by the name of Linus Yale, Jr. managed to mass produce locks with a pin and tumbler that became the most commonly used lock even to this day even though it is one of the easier locks to pick.

 

It is possible to use everyday items for lock picking, but these methods often damage the lock requiring expensive locks changing or repair services later. These do-it-yourself methods include using a screw driver to slide into the keyhole while working the knob to get it open, a pen’s plastic casing that often works on tubular locks like those used to secure bicycles, a soda can and scissors to open padlock combination locks by cutting out the bottom and inserting it against the inside of the shackle of the lock, a plastic bottle to cut out a rectangular sheet to fold and use like a credit card to jimmy the lock, or a paper clip or bobby pin that can be inserted into the keyhole and jiggled to position until you open the lock. Along with these items, you will also need an L-shaped piece of metal called a tension wrench.
