Are Your Keyed Padlocks Crashproof?

  When choosing keyed padlocks, it is important to consider whether it is susceptible to impact. Even though the keyed padlocks are made of strong and durable material, they can be opened by impact. Using special bump keys -- also known as knock keys -- a motivated thief can pry open traditional marble-keyed padlocks.

  What are keyed padlocks?

  Not to be confused with picking, bumping involves using a bump key to access and open marble keyed padlocks without the original key. A special bump key is used to mimic the mechanism of the original key. The thief inserts the bump key partially into the keyed padlocks, at which point he or she will attempt to open the keyed padlocks by "bumping" the key inward.

  To better understand how collision works, take a look at traditional marble keyed padlocks. In marble keyed padlocks, there are multiple spring pins. Each spring-loaded pin consists of two parts: a key pin and a drive pin. When you insert the original key into the keyed padlocks, the key pin and drive pin of each pin will be perfectly aligned, opening the keyed padlocks.

  The striker has teeth that drive the key pin into the pair of drive pins. After successfully aligning one pin, the thief will move to the next pin. The keyed padlocks will only open after all pins are aligned.

  Select keyed padlocks with custom-shaped pins

  In addition to the number of pins used in marble keyed padlocks, the shape of their pins also affects their sensitivity to collisions. Pins with traditional basic shapes are relatively prone to bumping. On the other hand, those with custom shape designs will have the false impression that the pin is properly aligned when in fact it is not.

  To prevent collisions, you need to choose keyed padlocks with lots of safety pins - these safety pins need to have a custom shape. These two features alone can protect your property from theft.
