How Do You Make A Bump Key?
A bump key is a device that can be made from a simple house key to help you should you find yourself locked out of the house. Locksmiths have been using them from upwards of 30 years. They can be purchased online as well, however they are much too expensive given the short amount of time and effort involved in constructing one. Such a key will work for any normal multi-pin tumbler lock, such as the kind you have connected to your deadbolt and front door. This is also an effective exercise in home security. Thieves have likewise been using bump keys with relative impunity for just about as long as locksmiths have. It’s unfortunate that people who tout home security have downplayed this information in an attempt to get you to purchase shiny new home security systems that do nothing to keep thieves out. Once you’ve made a bump key and given it a try, maybe you’ll be willing to pony up the extra expense of purchasing new bump-proof locks, which also happen to be proof against normal lock p
A bump key is a modified key that can be used to gain entry to locks. The key has all of the cuts to the maximum depth (999). This works by hitting the modified key causing the pointed and deep valleys to shoot the pins (also known as the billiard ball effect) above the sheer line causing the lock to open. • Lay out your key which you will make the bump key out of and the triangle file on a flat working surface. File down the key in between the pointed parts so that they create a sharp “V” shape. Make sure that the valleys between the points do not go below the indented line (I’m sorry i don’t know the proper name for this). Be sure you file down in between each of the points on they key or else your bump key may not work correctly.
