chiave a cratere con resina

The chewing gum as a technique of opening the locks ??

The chewing gum as a technique of opening the locks ??
For some time now I find myself making the interventions of substitutions on the Euro profile cylinder locks with key crater that apparently were opened without break.
How do I explain to the customer that not all European profile cylinders are safe even if they are equipped with proprietary card?
I can explain that there are various levels of security and, in the case of low levels, the protection of the bumping techniques, dell’impressioning is not guaranteed, as it is said that you can not decode the lock.
In some cases I found a piece of chewing gum in the cylinder, not a small part or a residue, but just a nice piece slipped and crushed nell’imbocco key cylinder.
From The chewing gum, also known as gum, chewing gum in English, is an absolutely particular confectionery product, because unlike all the others, as the name says, should not be eaten, but only chewed.
The question I always do it, but you can open a cylinder with chewing gum?
My answer is that there are techniques that are opening and not, as erroneously are called to “break.” And entering means a transaction which involves the forcing of the lock, in fact the term burglary is used in forensics when the locks or the locks or security are compromised functionality from an operation of burglary.
From “Burglary” means the term of a legal break area. There is, at base, an Italian verb, as, through the French effraction (documented since 1404), burglary is related to a noun medieval Latin effractio, -onis (according Ilgrande dictionary of the Italian language of the Battle) or Latin of all (former) ‘(according to the DELI of Cortelazzo-Zolli) effractus late, past participle of effringere’ break (shatter).
Burglary is witnessed in Italian wrote the chancelleries since 1812 in efrazione shape and since 1855 in the form still in use today.
By “opening” can mean both an opening in the true sense of the word and that is that I open the lock is understood that the lock can be opened, because using soft keys or modular I can achieve a working key; or I can decode the lock, that is taking the steps to implement a key in a traditional manner, from a raw key. These techniques are called NDE (Non-Destructive Entry). Within these techniques will definitely have to enter the methods of “picking” of ‘ “impressioning”, the “bumping” and “decoding”.
At this point you can define two possibilities:
if the piece has found the smell of chewing gum and cluttered all key entrance: I think it’s a joke, one red herring, simply want to avoid let us know which is the technique that really use. Technical really think we can definitely bring used as part of the NDE (Non-Destructive Entry). In this way they try to prevent the public’s knowledge arrivals to take knowledge of the technique used, and really make sure that the news does not disclose as it has been spread in the case of modular keys used in NDE openings of key locks dual map (tool or technique called also pick Bulgarian or Bulgarian tool).
if the piece was found as a residue of small size it is probably not chewing gum, but it is the reality of the wax or resin.
Opening techniques without break and without break, the NDE (Non-Destructive Entry), there are different and they change depending on the model and the type of lock. In the case of cylinder locks with the key in the crater or flat key cylinder (classic cylinder-piston) among the many which there may be two interesting, for both the speed of execution of the opening (to be precise the lock is openable and not open) allowing the realization of a key that works even if apparently seems maybe not a key, but only one blank. Both for the fact that at a later time you can make a final key by using the key NDE as a template or to take the necessary measures.
Among the techniques used you can be listed: the carry keys with resin or wax and keys with the graphite coating. It is always milled keys to the maximum depth (the lowest slot) and then, the part with the removed material, filled with a precisely these materials. Materials that are chosen based on the type of lock and by the type of realization of the lock. For example in the case of a crater keys depending on the cylinder and its features I can choose, on the basis of the tests carried out, if use of the resins or of stearic wax or other type of wax. In the case of cylinder-piston and the pump cylinder locks with my personal opinion it is that the graphite coating is the best, because he is tenacious enough to keep its shape and soft enough to be worked on and to highlight where to remove the material.
