90% of the keys are easily opened with any of the 10 key matching keys

Whether it is a cheap or high class key, if it is a key that adopts a classical form, it can be opened quickly by using only 10 key keys (or such a key) A shivering movie called. If it matches the shape of the key and the number of pins, it takes only a few minutes, just a few seconds, to open it if it is the shortest.

On average, it seems that 80% of keys can be unlocked in this way without damaging within 3 minutes, and 50% or more can be unlocked within 1 minute. Without "doing no damage" is the point, even I do not notice what was broken ....

Appreciation is from the following.
YouTube - Bump keying

The above movie is a documentary of the result of the interview by Dutch "NovaTV", and detailed about this technology which was interviewed "TOOOLThere is an original high-resolution movie on the page of. With English subtitles properly. Apparently it seems that we are distributing on the site after obtaining permission. It is not thought in Japan and other countries, but as expected it is the Netherlands.

This is a high-resolution movie (WMV format: 63.4 MB)

As a procedure of unlocking, I thrust the same kind of key with matching pin number etc, tapping with taunt and jumping up the pin, the feeling that the key opens. It is confusing. It is not a dedicated tapping tool, I am striking with the handle of the driver.

There is also an English version on the official website properly, and it is written about which kind of key is still relatively safe in the PDF file distributed there. However, safety in this case means "safe" in a way to open without causing this damage, and if you are willing to destroy the key, the story will be different again.

Previously, in GIGAZINE 's office I also exchanged the key, the person who said that the locker used at that time was originally a key maker and made various key prototypes. It is sad that even people like that will be restructured, but as a matter of course I was quite familiar with the key and heard many stories.

In conclusion, one key will be broken by any key if one key. The key A is strong for so-called picking, but there is a possibility of being destroyed, the key B is strong against destruction etc., but feeling that it is weak for picking. This is it! There is no such key as for general use. It is safe if it is a TV program! Like saying is a big lie.

The only key that is most close to perfect is the kind of key that is adopted in the bank's vault. The door itself is the key. When opening it is also a type that unlocks the lock by turning the handle around the handle. You can find out by inquiries with a metal huge latch on the top and bottom of the door. It seems that it will also be attached to ordinary households, even if it costs money. Well, in addition to being so high as to jump out, we have to put in our hands from the construction phase of the house ... but it is not good. However, it seems that there are also families actually employed (not naturally a house where ordinary people live). That's why most keys will be opened unless it's at that level.

However, if there are two or more keyhole in one door, furthermore it is a type that is made tough with chains and other things, it certainly opens if it takes time but conversely when it takes time to open it, Risk is raised if it comes from, so we are wary of entering the preliminary stage first.
