A bump key is a lock-picking tool used to override many locks almost instantly. So, if your whole house has Evva locks, an Evva bump key could open every door. Y'all can make i from a blank key, as long as yous have the real fundamental or lock as a guide. Bump keys are unremarkably associated with lockpicking and burglary, just this how-to is strictly for legal purposes. Only open doors legally, and store your crash-land key in a safe place.

1. 1

   Buy a blank key that matches the model of the lock you lot're picking. If yous're trying to make a bump cardinal for a Kwikset lock, y'all'll demand a blank Kwikset key. ^[1] To brand a crash-land lock, you'll need the key from the right manufacturer also as a working copy of the legitimate key.

   • At that place are some people making crash-land keys without original keys every bit guides. To practise so, y'all need an electronic caliper capable of measuring the distance between pins in the lock -- a complicated maneuver reserved usually for burglars without access to an original.^[ii]

2. two

   Review the basic vocabulary of keys before moving forward, specially if you lot are new to lock-picking. This how-to will employ certain terms and phrases to refer to parts of the key. Knowing the simple terms will help you lot make a more effective fundamental.

   • Length: the length of the primal from its tip to the end; the longest measurement of the key.
   • Groove: a dip or indentation in the serrated edge of the key. Each groove is next to at least one summit.
   • Peak: a tooth in the serrated edge of the knife. Peaks tin can exist steep or apartment, but jut outwards from the body of the key. Each peak is next to at least one groove.
   • Maximum depth: the length of the deepest groove on the primal. The deepest groove should never cross the track.
   • Track: the narrow indentation along the key's length. Different keys take differently sized tracks. The track falls roughly in the heart of the key length-wise.
   • Shoulder: when the key is inserted, the shoulder sits at the elevation and right outside the lock's archway. The shoulder stops the key from existence inserted also far into the lock.

3. 3

   Utilise a fine permanent marker to trace your real key onto the blank one. You lot demand to know where each groove is along the length of the primal, equally well as the maximum depth that whatsoever groove has on the key. Lay your existent key over your bare central. The but difference between the two is that the real key is serrated where the blank key, your bump key, is not. You lot just have to trace that serrated border. ^{[3] [iv]}

   • The maximum depth should never cross the rails, which is the indent going through the length of the key.

4. 4

   Stick the blank key in a demote vice. Place the central then that the track and lesser are in the vice and the elevation sticks out. Y'all will demand to file the key into the shape you've outlined. You can ready the original key aside.

   • If you do non accept a bench vice, find another fashion to hold your key deeply while filing it down. You lot must exist able to file downwardly to an authentic depth, so having information technology somewhere it tin't move is crucial.

5. 5

   Utilise your file to arts and crafts the bump key into a rough approximation of the original. Employ the file, keeping the peaks in place. Your biggest goal is to never go lower than the maximum depth of the original. Just get the key into the rough shape of the original and then yous tin can fine-tune it into a bump primal.

1. 1

   Use a metal, triangular or taper file to grind the grooves into the bump key. The biggest affair to focus on is the depth of each groove. Y'all never want to become past the tread running along the bottom of the key, and you never desire to go deeper than the maximum depth of the original key.

   • Practice not worry about the sharp peaks between grooves for now -- they come side by side.
   • You should have the same number of grooves as real the fundamental.

2. 2

   File all the steep peaks down so they are only four-5mm above the grooves. The peaks of your blank key are probably too high and might cause your key to get stuck in the lock. File down the peaks so that they are a few millimeters loftier. The right height is one that triggers your lock but doesn't get stuck; you may take to experiment and practice to find the correct height.^[5]

   • Your peaks should be of equal height to one some other.
   • The peaks just need to be high plenty to grab in the lock.

3. 3

   Use your file to clean upward the primal so that all the grooves and peaks are at matching heights. Your terminal crash-land key should look similar a saw with an evenly serrated, jagged edge. The little, toothy peaks, shouldn't be too steep, and the grooves should be evenly spaced right where the grooves on the original central are located. Information technology is okay if the grooves are flat-bottomed.

4. iv

   Find the shoulder of the key. Insert your bump key into its corresponding lock, noting where the primal stops it from going any further in. This is the shoulder, which exists between the grooves/peaks, and where your fingers grasp the fundamental in order to use it. The shoulder exists to stop the entry of a key into a door at exactly the correct location so that the grooves and peaks align with the lock.^[6]

5. 5

   File the shoulder downwardly into a flat line. The shoulder controls how far the key goes into the lock, but you don't want the shoulder there. Using a crash-land key, you want to be able to control how far the key is going into the lock to jiggle the lock open up. Getting rid of the shoulder allows y'all to position the fundamental every bit you lot want while tapping it in. Use your file to wear the shoulder downwards to the tiptop of your peaks, at least. ^[7]

6. half-dozen

   File downwardly the tip of the key. This is an optional step, simply can help you fit the central in.The tip is the part of the primal that inserts into the lock first. If you lot are having problem fitting and jiggling the key into the lock, try filing down the tip of the key by 1/four to 1/2 of a millimeter.

   • You volition need to fit small condom spacers on this area, allowing you to "bump" the central confronting the lock so it recoils back a bit at y'all.
   • This is called the "minimal move" method. ^{[8] [nine]}

1. 1

   Identify your bump key in the lock to test the required length. Encounter where the shoulder used to exist? Using your permanent mark, draw a dot or line where the primal emerges from the lock. This marker should exist right where your bump primal'southward shoulder used to exist.^[ten]

2. two

   Place rubber rings on the key where you fabricated you marks. Slide them onto the key and position them where your key's shoulder used to be, starting at that mark you drew. To apply a crash-land primal, you want bouncing rubber where a real key has a metal shoulder. This way, the cardinal will bounce back out a petty every time to hit it into the lock. A skillful bump key will jiggle around in the lock fluidly until it properly aligns with the lock, and will not get stuck.^[11]

   • If yous practise not have rubber rings, you lot tin can still test your bump key. Y'all volition accept to reset the fundamental in the lock afterwards every time you hit it, though. This is called the "pull-back" method. ^{[12] [13]}
   • Any footling rubber ring volition exercise. You lot could utilise gaskets from the plumbing section of a hardware store, farm equipment, and hosing.

3. 3

   Identify your bump central into the lock. If you button on your bump cardinal and hear a click, then move on to the next step. If y'all do not hear a click, jiggle your fundamental or consider filing one-half a millimeter off from the tip of the key.

   • If you have safety rings, your key should bounce back to its original position in the lock every time yous push in and let go. ^[14]
   • Without rubber rings, yous must pull your central back out one notch afterwards pushing it in once.^[15]

4. 4

   Turn the key slightly clockwise. Using i hand, apply lite rotational pressure. It should exist as if you were trying to plough the central to unlock the door. ^[xvi]

5. five

   Hit the key into the lock lightly to "bump" it open up. Hold a small hammer, the dorsum of a screwdriver, or another mallet-like object in the hand not holding the central. Hitting the key straight in the direction of the lock, bumping it several times while still rotating the key slightly. This will probably take a number of tries. Jiggle the key if needed.

   • With rubber rings, you can hit many times in quick succession.^[17]
   • Without safety rings, you must pull your fundamental back out one notch after pushing it in. This can get tedious, but it is non impossible.^[18]

6. 6

   Open up your lock and remove your bump key. Keep information technology in a safe place and utilize information technology only for legal purposes. Notation, nevertheless, that improperly fabricated or used bump keys tin permanently impairment locks. Just use your crash-land key when you are admittedly sure yous demand it, as it can cause more headaches than it is worth if you aren't careful.

   • The actual "bumping," or knowing how to turn the cardinal and how hard to hit information technology, will have some practice. Each lock is slightly unlike, simply you'll learn to get the feel for it with some practice.

• Question

  What if I don't take access to the original fundamental, but have used keys that fit in the lock only won't unlock it?

  

  Become to a motorcar dealer and show your license and registration. There is a way they tin make your primal.

• Question

  My original keys wont work afterward making the copy keys. But the copy keys work fine. How is this possible?

  

  More likely your original keys and lock (which we can consider as only the unlike size brass (usually) pins in the tumbler) these surfaces have worn down slightly over time. And then, when you copied your original keys (depending on how the bare keys are cut, information technology could be a little different from the original). Now where the peaks and grooves of your original keys are worn downwardly some, the peaks and grooves on your new keys are not worn downwards, and will have precipitous edges if their not smoothed over some. Anyway, what likely happened is your new keys with their sharp edges/taller peaks, etc., cut into or wore downward the tumblers in the lock after a few uses, and now your old "worn down" keys no longer work.

• Be careful of your fundamental getting jammed in the lock. This tin can happen later on hitting or jiggling your fundamental. To lower your take a chance of jamming, sand your crash-land central so it has few rough parts and employ harder metals. ^[19]

• When using the bump fundamental apply very slight tension. ^[20]

• Exist careful non to carve the grooves lower than the track, the indented line in the cardinal.
