Five problems in the collective protection of the stolen lock industry in Xi'an

[ Hui Cong Hardware Network ] In the early morning of November 13, 2009, 6 households in a residential area in Xi'an were stolen, but the doors and windows were not damaged. Yang Yucai, an investigator of the Xi'an Public Security Bureau's Technical Defense Office, analyzed in an interview. It must be that the thieves used professional technical tools to open the door lock. This incident exposed at least five major problems in the lock industry.

Question 1 - Standard old anti-theft lock is qualified but not anti-theft

It is understood that the current standard of mechanical anti-theft locks was promulgated in 1994. According to the standard, mechanical anti-theft locks are divided into two standards: A and B. The anti-destructive opening time of the A-level anti-theft lock should not be less than 15 minutes, and the anti-technical opening time should not be less than 1 minute: the anti-destructive opening time of the B-class anti-theft lock should not be less than 30 minutes, and the anti-technical opening time should not be less than 5 minutes.

At present, about 60% of consumers in Xi'an market use A-class anti-theft locks, that is, if you use professional tools to open the door locks, it can't be less than one minute. "In fact, many A-class anti-theft locks can now be opened in less than a minute. This is not a failure of the lock. The standard was established in 1994. It has been a standard for more than a decade. Know the theft. Technology continues to 'progress', but many manufacturers have not updated the technology, still in accordance with the old standards of the past, the quality of the locks produced is also qualified, but in fact no anti-theft!"

Question 2 - Lock production and cut corners

The lock itself is cutting corners and is also a reason for the increasing number of burglaries. Good locks should use pure copper, but some merchants will use recycled copper. This kind of copper is not hard enough. After a long time of use, the keys will be smoother and smoother. For thieves, it is more convenient for theft. Some manufacturers will use iron or aluminum, and the hardness is even worse. In addition, manufacturers reduce the number of processes in the production process, reduce the fineness, reduce the number of marbles in the lock cylinder, and reduce the safety performance of the lock.

Question 3 - Excessive supervision of the lack of necessary supervision

It is understood that Xi'an is active at least two or three hundred unlocking companies. According to Zhang Lixin, director of the Xi'an Public Security Bureau's Technical Defense Office and Security Association, most of the unlocking personnel are responsive to the needs of customers, and they do not verify the identity of the owner. "There was such a thing last year. Two people from Shandong came to Xi'an to find a lock-up company. They asked for the training of professional unlockers. The lock-up company did not review the visitors. If they paid the money, they would give training. Who knows these two people? Actually, it was the leader of a theft group. After they learned the technology and returned to Shandong, they began to steal a lot of cars. When the public security department solved the case, they stole a total of tens of millions of cars!"

Zhang Lixin believes that there should be control over the qualifications and number of professional unlocking personnel and unlocking companies. Four or five years ago, people found that there was market space for unlocking, because people took the key to climb windows or even fall down the building. Because of the existence of the market, the unlocking company quickly developed, but the development was too fast. The lack of necessary supervision has become a new problem.

Question 4 - Professional unlocking tools are extremely easy to buy

Yang Yucai said: "Professional unlocking tools are sold all over the Internet. The variety is very rich, and it is very professional and advanced. This is very worrying!"

The author searches for "unlocking tools" on the Internet. In less than half a second, all kinds of rich unlocking pictures are all presented. If you continue to click, the manufacturer's contact phone number and sales hotline will appear. It can be said that ordinary consumers buy professional ones. The unlocking tool is very convenient, which also facilitates the thief.

Question 5 - spend a lot of money to buy a house, do not want to spend a small money for a lock

Zhang Lixin told the author that many home security door locks are urgently needed to be upgraded. The ordinary A-class anti-theft lock can be easily opened with steel wire, iron piece and tooth mold. For the old-fashioned security door with cat eyes, the thief only needs to open the cat's eye first. Through the cat's eye hole directly with an iron hook, you can open the door lock and break into the door.

As the president of the Shaanxi Branch of the China Locksmiths Club, Zhang Lixin told reporters that in order to promote the popularization of security knowledge for ordinary residents, from the beginning of this year, he visited many communities in Xi'an and personally gave many residents publicity, hoping that they could upgrade their homes. The door lock, but most people react very indifferently, think that the lock at home is very good, nothing to do, spend so much money to change the lock.

Zhang Lixin said: "Everyone would rather spend hundreds of thousands to buy a house, and would not spend a few hundred dollars to change a good lock, unless it is really stolen at home, they would like to replace it. So, six residents in this community were stolen. Let everyone ring the alarm, security awareness everyone needs to improve together!"
