Reliability that is immediately visible!

Many entrance doors are equipped with common brass cylinder locks (sometimes called bots). There are several ways to open such a lock: drill, knock out, break, use a master key. The main models of cylinders produced by the Italian company CISA (CHIZA), have protection against drilling (hardened steel inserts), against sledgehammers (burglar-resistant pins, reinforced housing), against unauthorized duplication of keys (numbered keys produced only for the bearer of the Secutity Card holder), against a master key (up to 8 billion key combinations, interactive movable element). Additional protection is provided by the installation of special protective armor plates.

If, nevertheless, the entrance lock was broken, but the robbed apartment is insured, then the owners have a chance to compensate for the damage incurred – if the fact of burglary is proven to exclude the situation when the owner himself took out the things, and then applied for compensation to the insurance company. In this situation, today you can face a serious problem: the apartment is robbed, the door is open, but the lock is not damaged – it is fully functional! If this happened, then we can assume that the door was opened by one of the new methods of hacking, information about which appeared on European sites 2 years ago. This method is called bumping.

Bumping is a method of longitudinal impact on a cylinder lock. The name of the hacking method comes from the English word “bump” – “knock, blow”. And the process itself looks like this: an attacker needs a special key blank (bump key) and a small hammer. The burglar inserts a bump-key into the lock and starts tapping it lightly. Due to vibration, the secret mechanism of the lock can adapt itself to the bump key, which must be turned in the keyhole. A little patience and the door is open. Now only a special examination can help the owner prove the fact of hacking. But isn’t it better to warn the danger in advance??

imageCISA gave a worthy answer to this challenge of the criminal world. First of all, it was proved that the serial cylinder CISA RS3 with interactive movable element (CISA patent), bump-proof. But since the super reliable cylinder RS3 does not belong to the class of cheap cylinders, CISA set the task to develop a method of protecting other cylinders, primarily the most popular and demanded – series ASTRAL and AP3. Today CISA solved this problem by obtaining a patent for matching cylinders RS3, AP3 S and ASTRAL S European standards EN 1303: 2005, including the requirement for protection against bumping. In Russia, tests of these cylinders were carried out in a specialized laboratory of the FSB, which also confirmed their compliance with the specified requirements..

Cylinders AP3 S and ASTRAL S have special markings “BKP” (Bump Key Proof – anti-bumping). How is such a high level of burglary resistance achieved? Note that the letter has been added to the cylinder name at the end S – abbreviation of the Italian word Sigillo (free translation – “with seven seals”). The design of these cylinders includes an insert of six hard hardened steel plates (for added strength) and one flexible stainless steel plate (for flexibility). The insert runs the entire length of the cylinder and is visible from both sides, even when the cylinder is mounted in the lock. The intruder recognizes the protected cylinder at a glance, which can make him refuse to hack! This means that it is much easier to prevent an attempt to open the lock than to eliminate the consequences. If your house is reliably protected, then this means not only the safety of property and nerves, but also care for those close and dear to you.!
