Block Hit – The Truth!

There are many and varied articles that appear in this medium that give an inaccurate explanation of lock-bumping. Having read many similar articles here, trying to impart the facts about the phenomena, I can’t help but feel that all these “so-called” experts actually have no idea what they are talking about. Lockpicking was known and existed before the invention of the modern trigger principle by Linus Yale Jr in 1862.

The original design of the bolt method was found in ancient Egypt, where actual models of a wooden bolt lock were found during excavations of ancient sites. One of the oldest of these locks is on display in the Israel museum that houses the original Dead Sea Scrolls. In fact, the modern Yale-type key cylinder uses two sets of pawls combined with springs and a “protected” keyway to establish a locking mechanism that is perceived as secure.

Lock striking focuses on the ability to recreate the “cut” line, normally created by the correct original key for the cylinder, by using a key of the same guard design as the target cylinder, but modified to the depth maximum for each position of the drum. (the cuts in the key).
The striking key is inserted into said keyway, partially. The head of the key is struck with a hammer or screwdriver, while exerting minimal torque pressure on the key. The action produces enough kinetic energy to “hit” the pin drums inside the chambers to recreate the “cut line.”

While previous authors suggest that the method was discovered by locksmiths in Denmark in the 1970s, the truth is that virtually all locksmiths know about bypass FOREVER! The main reason the lockdown hit was kept quiet and inside the trade was to protect the market from the possible sense of insecurity that the knowledge could bring.

Only since the advent of the Internet has the phenomenon spread like a virus onto the scene. There are a few manufacturers that have reacted to this hype and produced their own “shock resistant” versions of locks, but most of their attempts have not created products that are 100% guaranteed to be shock proof. There are already two types of fully guaranteed shock-proof (and virtually pick-proof) key cylinders available today. Abloy and Bilock. Abloy is of Finnish design and has been around since 1908, while Bilock is an Australian design that has been around since 1972.

Contrary to the beliefs of some of the above authors, these shockproof locks are not “that” expensive and are aesthetically pleasing and readily available throughout the world. Truth be told, instances of lock hits are almost impossible to detect due to the fact that the action represents the use of a key.
