A lot of people are looking online for information on how to make a bump key. If you’re familiar with bump keys, then you know why this is the case. After all, more and more people are warning about the potential security threats with this relatively easy lock picking technique. But still, you probably want to know how to make one because you want to see for yourself if it’s really that easy. If you’re not familiar with them, then it’s in your best interest to arm yourself with the knowledge because there’s a good chance that you’re at risk.
What is a bump key?
A bump key is a key that’s crafted in such a way that it will work with just about any lock that has pins. It’s one half of the tools that are needed to bump locks, with the other half just lying around your home.
It’s sometimes called a 999 key because it’s filed down to maximum depths which locksmiths call the 999 depth.
What locks will it pick?
Bump keys are designed to defeat locks that have pins in their mechanisms. So in theory, they can pick pin tumbler locks. They also work perfectly with just about any type of cylinder lock. Should you be concerned? Well, you should be considering the fact that research has shown that 9 out of 10 homes in the US are protected by cylinder locks.
Also, don’t make the mistake of feeling secure with high-quality locks. If you think that their precision is working for you, you have to know that it actually makes it easier to bump the lock. In addition, here are the things that you have to consider when it comes to choosing locks:
- Security pins (mushroom or spool) don’t guarantee that the lock cannot be bumped. At the very least, they’re going to make it a little harder.
- Lock pickers love hardened steel. This is because hardened steel can help them escape detection. While lock bumping doesn’t cause any damages when done correctly, hardened steel will prevent damages if you’re not too careful.
What locks will protect you?
Through the years, lock manufacturers have put up security measures in their locks to make them “bump-proof”. Unfortunately for a lot of burglary victims, they never really succeeded in the past. Fortunately, lock manufacturers were able to catch up. There are now locks and security measures that can help you. Here are the most effective ones:
- Shallow drilling
Lock manufacturers brilliantly thought of the idea of having several pin stacks drilled shallower than the other pin stacks. This way, the bump keys won’t be able to bump the pins up since the grooves can’t reach the pins.
The locks of BiLock don’t use pins. Instead, they give the legitimate lock owners a lock code that’s used on the programmable side bars. The company claims a 0% success rate in attempts to bump their locks.
- Abloy Protec
This lock doesn’t have any pins on them that can be bumped. Instead, they utilize a disc tumbler system. The company wants their locks to be so secure that you’d need the included signature card to request for a spare key.
- KwikSet SmartKey
The KwikSet SmartKey one-upped the Abloy Protect by taking out the tumblers as well. Instead of pins or tumblers, this system uses a side locking bar.
- Spring-less locks
If there are no springs, there’s nothing to bump. This is why electronic and magnetic locks work. However, you have to make sure that they don’t have backup locks that can be opened by keys. That part can be bumped.
Things that you need to make one
You’ll be surprised at how easy it is to accumulate the things that you need to make a bump key. You’ll be even more surprised at the number of things that you need.
A blank key works best. However, any old key that you don’t need works just fine. Just make sure that the blank or old key is designed for the type of lock that you want to bump.
- Triangular file
Sure, you can use any shape of file. However, a triangular file works best since they fit perfectly on the valleys of the teeth of the key. In addition, you’re going to file the bump key and form a triangle in the process and a triangular file will take care of that.
- Strong table
Actually, any strong and flat area works just fine. But a strong table that you’re already comfortable with will work best.
As you can see, you don’t even need to go outside your home to buy the needed equipment. Once you have accumulated the needed equipment, you can now make your own bump key.
How to make a bump key
Just follow these simple steps in order to make your own bump key:
- Determine the deepest part of the key’s grooves. Do you see the first straight line that’s directly below the grooves? That will be your guide.
- Hold the key’s handle with your non-dominant hand and place the key on the table. Make sure that the teeth are facing upwards.
- Get to work! File down the valleys in between the tips of the teeth until you get to the deepest part. It’s a good idea that the valleys will form sharp triangles because a lot of people swear that they make the bump key more effective.
How it works
You won’t know how it works just by looking at it. But it’s actually very scientific. It actually works using the third Newton’s law of motion. This law states that, “To every action there is always an equal and opposite reaction.” Lock bumping works by inserting the bump key inside the lock and bumping the head so that the teeth of the key will force the pins upward. You’ll then catch the pins as they’re going down and you’ll be able to turn the key as they get in place on their way down.
Lock bumping is simple. Making bump keys is even simpler. That answers the question as to why there are a lot of people that are taking advantage of them.
