This set comes with the most common residental locks and the most common padlock key, we sell this set to a lot of property owners for this very reason. i would suggest getting a bumpp hammer as well http://www.bumpmylock.com/bump-keys/bump-hammers.html this will save you a lot of time and make learning the proccess a lot easier.

Is this the best set for residintal locks? I manage many rent houses and the clients are always changing the lock and moving out with out giving me a key. and what else do I need to make this work.

I have opened padlocks and doorlocks in this fashion. If you get the torque pressure just right it can open a lock in one stroke. Otherwise it can take a few strokes.

Scrubbing is fast because you don't need to pay attention to individual pins. Consider the effect of running the pick over all the pins with a pressure that is great enough to overcome the spring and friction forces but not great enough to overcome the collision force of the key pin hitting the hull. Any pressure that is above the flat portion of the force graph and below the top of the peak will work. As the pick passes over a pin, the pin will rise until it hits the hull, but it will not enter the hull. The collision force at the sheer line resists the pressure of the pick, so the pick rides over the pin without pressing it into the hull. If the proper torque is being applied, the plug will rotate slightly. As the pick leaves the pin, the key pin will fall back to its initial position, but the driver pin will catch on the edge of the plug and stay above the sheer line. In theory one stroke of the pick over the pins will cause the lock to open.

In practice, at most one or two pins will set during a single stroke of the pick, so several strokes are necessary. Basically, you use the pick to scrub back and forth over the pins while y ou adjust the amount of torque on the plug

1.) Insert the pick and torque wrench. Without applying any torque pull the pick out to get a feel for the stiffness of the lock's springs.

2.) Apply a light torque. Insert the pick without touching the pins. As you pull the pick out, apply pressure to the pins. The pressure should be slightly larger than the minimum necessary to overcome the spring force.

3.) Gradually increase the torque with each stroke of the pick until pins begin to set.

4.) Keeping the torque fixed, scrub back and fourth over the pins that have not set. If additional pins do not set, release the torque and start over with the torque found in the last step.

5.) Once the majority of the pins have been set, increase the torque and scrub the pins with a slightly larger pressure. This will set any pins which have not set low due to beveled edges, etc.

Will this key work?

i dont think so, the spacing looks off. it is not recomended to make your own key. if you make a mistake you can ruin the lock.

I actually use a tension wrench through the hole in the key when I bump. That way it's easy to control the tension and you don't hit your fingers.

I have found that by installing a simple rubber gromet over the cut part of the key to the end of the cuts, that it will hold the key out and compress when the key is struck with the hammer, but allow the key to return to the original pre strike position. This method has greatly inproved my success in bumping locks.

You pull the key out just a bit, ( about 1/16 to 1/8 inch) then you would use a bump hammer to bump the key into the lock (like a nail in a board with a hammer) you can check out a video off the proccess on our site http://www.bumpmylock.com/video.

The most common mistake when lock bumping is putting to much turning presure on the key, once the key with pulled out one notch (about 1/8 of an inch) you need to hold turning presure like you where using a tension wreach and hold the presure while you bump.

I am confused does bumping mean sliding the key in and out rapidly while applying slite preasure

by looking at a lock how can you tell if it has 5 or 6 pins?
I am realy new at this but it sounds like a great hobby for a old foegy like me

I was trying to practice bumping the door knob lock on my front door and having trouble. Are there any tricks I'm missing? How do I know how far out to start the key before I bump it?

you can do this with some lock it depends on how the pins are set up, if you have the pins set in a high position it is posible that a key with ridges lower will bump the lock.

Nice description! I have a friend I was talking to about bumpkeys and bumping locks. She said she has bumped padlocks but not with a bumpkey....she was bumping padlocks with whatever key would fit it the lock. I didn't see it done but she sounded like she knew what she was talking about. Interesting huh?

A pin tumbler lock is composed of a series of spring-loaded stacks called pin stacks. Each pin stack is composed of two pins that are stacked on top of each other: the key pin, which touches the key when it is inserted, and the driver pin, which is spring driven. When the proper key is inserted into the lock, all of the key pins and driver pins align along the "shear line," allowing the cylinder to turn. When the different length key pins are aligned at their tops by the insertion of the correspondingly cut key at their bases, the tops of the key pins and, consequently, the bases of the driver pins, form a straight line, so that the cylinder can be turned, rotating the key pins away from the driver pins. When no key or the wrong key is in the lock, pin misalignment prevents the cylinder from turning.
When bumping a lock, the key is initially inserted into the keyway one notch (pin) short of full insertion. Bumping the key inward forces it deeper into the keyway. The specially designed teeth of the bump key transmit a slight impact force to all of the bottom pins in the lock. The key pins transmit this force to the driver pins; the key pins stay in place. This physics action can be visualized by observing the same effect on the desktop toy: Newton's Cradle. Because the pin movements are highly elastic, the driver pins "jump" from the key pins for a fraction of a second, moving higher than the cylinder (shear line of the tumbler), then are pushed normally back by the spring to sit against the key pins once again. Even though this separation only lasts a split second, if a light rotational force is continuously applied to the key during the slight impact, the cylinder will turn during the short separation time of the key and driver pins, and the lock can be opened while the driver pins are elevated above the keyway. Lock bumping takes only an instant to open the lock. The lock is not damaged in any way. Certain clicking and vibrating tools designed for bumping can also be used. These allow for rapid repetition of bumping against locks that have advertised "bump proof" features. Only a rare few key-pin locks cannot be bumped. Electronic locks that have a key backup are obviously completely susceptible to this method.

You can pick locks with almost anything.

Just for fun I have used paperclips, bobby pins, bits of wire, street cleaner bristles and homemade picks ground with a dremel out of hacksaw blades. All can pick but not as nicely as picks I have bought from this site.

A small allen wrench can be ground into a nice torque wrench. Street cleaner bristles make nice torque wrenches and lock picks too.
