A smart prepper knows that a locked door doesn’t guarantee total safety. For a person who knows how to pick locks, this is only a minor obstacle.
Lock-picking is commonly associated with criminal activity, but it’s a useful survival skill. Here are some scenarios where lock-picking skills may come in handy:
Despite its usefulness, not everyone has a lock-picking set they can use. In fact, some countries (like Japan) outright ban them. If you want to learn this prepping skill, you can use a bump key. They’re easy to use, and you can make one yourself. (h/t to UKSurvivalGuides.com)
A bump key refers to a key whose ridges are cut to the maximum depth (999). Sometimes called a “999 key,” the low ridges make it possible to pick pin-tumbler locks, which are the most widely used locks in the world, including household doors. With a bit of maneuvering, a bump key allows the holder to pick the lock open.
Bump keys are different for each manufacturer. For example, if you have a Yale lock, you need to use a Yale key for a bump key. It’s best to prepare a set of bump keys from the most common brands of locks, like Kwikset and Yale.
When you use a bump key to gain entry, it’s called “bumping.” The most common way of using it is the “pull-back method.” In this method, the holder lightly taps a bump key in order to jar the pins inside the lock. This causes the pins to jump slightly for a second, allowing you to turn the lock.
How to do the pull-back method:
Another way to use the bump key is called the “minimal movement.” It follows the mechanics of the pull-back method with small differences. In this method, you file 0.25 to 0.5 mm of the key tip and shoulder. This allows you to insert the key deeper and have more leeway with the lock.
There are bump keys you can buy, but as a prepper, it’s best to learn how to make one yourself. You can practice using your old keys. Follow the instructions below to make your own bump key:
At this point, you must have realized that your own house is vulnerable to bumping. Aside from being an advantageous skill when SHTF, knowing how to pick locks helps you set up precautions against them. Here are some ways to protect your home from bumping:
Common locks have keys and pin-tumbler systems, which make them prone to bumping. Companies have tried improving their designs by adding features that reduce risks in bumping, but they are not foolproof.
Bump-proof locks are expensive, but they offer a lot of security. If you can’t afford one, ask a locksmith to replace the original pointed pins with mushroom-shaped ones. It may not be foolproof, but it makes the lock harder to bump.
The simplest way to improve your home security is to add other security measures. It can be big additions like a CCTV system with a camera facing your door. It can also be something small, like additional locks.
Bumping is a skill with advantages and disadvantages. With the right use, it can help others. If used by the wrong hands, it’s best to be prepared for them. Learn more about setting up security measures in your home at Homesteading.news.
