When she came back from buying vegetables, she found that she could not enter the house. She contacted Zhang, the master of unlocking, to open the door for her. Both parties agreed that the cost of unlocking was 150 yuan. According to the work requirements, Mr. Zhang asked Ms. Wang to provide her ID card to verify her identity before opening the wrong door. Ms. Wang said that her ID card was at home, and she would check it for Mr. Zhang after opening the door. So Zhang opened the door for Ms. Wang with professional tools, and Ms. Wang paid Zhang 150 yuan to enter and lock the door.

on January 2, 2016, the reporter invited your company to demonstrate the one word lock cross lock anti-theft door AB lock second open for us. Improve the public's knowledge of anti-theft and safety.

Experiment 1: "filling" key slot for locks: class a lock cylinder, class B lock cylinder

Professional unlocking time: 12 seconds

reporter unlocking time: 20 seconds

unlocking process: Master Wang first fixed a Class-A lock cylinder on a small vise, then took out a piece of tin foil and a * * key made in advance, and began to simulate the unlocking process.

Starting from the time when the * * key is inserted into the lock hole, master Zhou only takes 12 seconds to open this A-class lock cylinder easily.

According to master Wang's unlocking steps, the reporter uses the same unlocking tool to try to unlock. In the 20th second, the lock cylinder is opened.

Master Wang said that this unlocking method is to use tin paper to "fill" out the key slot, which is equivalent toMake a disposable key on site, so the unlocking process is effortless, just like using the original key. This method can be opened under the condition of anti lock and non anti lock of class A and b lock cylinders, but it is invalid for super class B lock cylinders.

Experiment 2: "hitting" lock cylinder

for locks: A-level lock cylinder and B-level lock cylinder

unlocking time for professionals: 4 seconds; reporter * * failed, and the second unlocking time was 6 seconds

unlocking process: Master Wang first inserted one end of a * * key into A-level lock cylinder, and then hit the other end of the key with hammer. During the beating, he will try to twist the * * key. After inserting the key, the master only hit it with a hammer, and the lock cylinder was opened, taking 4 seconds.

Because this unlocking method has certain requirements for the technique, the reporter cannot unlock the lock after striking for many times. The second attempt takes 6 seconds to open the lock cylinder.

It is understood that this unlocking method is the same as the previous unlocking principle, which mainly uses the design loopholes of class A and b lock cylinders to hit the lock cylinder bullets to achieve the purpose of unlocking. For the anti-theft doors with a and b lock cylinders that are not unlocked, it only takes a few seconds for the right thief to open them. If the lock has been anti locked, the crime time will be extended several times or even longer.

Because the internal structure of super-B lock cylinder is more complex, this unlocking method is invalid for super-B lock cylinder.

There is a piece of news on the Internet recently: in a few seconds, a thin piece of tin paper and a pair of professional unlocking tools can easily open the door lock. This makes many people worry: my door lock, safety?

Experiment 3: "insert" lock tongue

for locks: class a lock cylinder, class B lock cylinder

ProfessionalUnlocking time for people: 6 seconds; reporter unlocking time: 9 seconds

unlocking process: the experiment requires a made rectangular plastic card. Mr. Zhou first inserted the card into the gap between the door and the door frame, then slid it down to the location of the lock tongue, and then opened the door smoothly. The whole process took master Zhou 6 seconds. The reporter uses the same method to unlock the lock, taking 9 seconds.

This kind of crime is a more primitive means of unlocking the lock, but it is more common. The crime is more common in old residential areas. The thieves mainly target at wooden doors and old anti-theft doors. In fact, it is very simple to prevent the door from being "plugged" open, as long as the lock cylinder is reversed or the safety latch is inserted. This unlocking method is invalid for super-B lock cylinder.

More ways to prevent unlocking need to be improved

Chewing gum lock: the thief chews the gum soft and plugs it in the lock hole, and uses tools to push the softened chewing gum into the lock hole.

When replacing the lock cylinder, we should pay attention to the following four aspects: first, to improve the safety level of the lock, we only need to replace the lock cylinder. Consumers can dismantle the lock cylinder by themselves, and purchase the higher-level lock cylinder according to the specifications and models of the removed lock cylinder. In general, regular anti-theft doors can replace the lock cylinder without replacing the whole door and lock.

Second, consumers should pay attention to the model and specification of anti-theft lock, one-to-one replacement. Generally, the outline and installation dimensions of class B lock cylinder and common lock cylinder are unified. There are also special anti-theft door locks with different specifications. Please confirm the specifications of the lock cylinder before purchasing.

Third, the price of class B anti-theft lock cylinder is more than 200 in the hypermarket, so it is recommended that consumers choose regular brands. It is also a class B lock, but also to choose products of good quality. At present, there are many kinds of key materials. Copper or aluminum iron alloy is easy to be copied. At present, the better material is steel.

Fourth, the national standard only has A-level lock and B-level lock, and there is no super B-level lock and C-level lock. At present, super-B lock and C-level lock on the market belong to the concept of enterprise self-determination, but super-b-level lock and C-level lock must reach national B-levelThe basic requirements of lock, that is, super B-level lock and C-level lock can be regarded as B-level lock.

First, let's know what kind of lock is called super-B lock. Super-B lock cylinder is monitored by relevant departments. It is called "super-B lock cylinder" according to the standard that technology cannot be opened or technology can be opened for more than 270 minutes.

The advantages of super-B lock are: adopting multiple anti-theft technologies, multiple special-shaped anti pulling bullets, eliminating technical opening, cooperating with unique bullet and blade structure design, it has high safety performance of anti-technical opening. The lock box is equipped with precise number and special-shaped bullet structure, which will automatically lock when the number and special-shaped bullets must be pulled out at the same time when the technology is opened, so that the technology can not be opened. The lock cylinder adopts multiple combinations of different shaped marbles, and more can be programmed with billions of key numbers, so as to realize zero mutual opening (1 / 16 million) of the area. The lock cylinder is added with a side internal pressure type side column pin clamping device, which greatly improves the ability of preventing violent and strong torsion.

The difference between super-B locks and other types of locks:

A: the keys are flat or crescent, with one or two rows of concave keyways on one side or two sides or convex keyways on four sides of the cross;

b: the keys are flat or crescent, with two rows of concave keyways or cylindrical multi-point concave keyholes on one or two sides;

super-B: the keys are flat, with two rows on one or two sides Concave and S-shaped keyway, or internal and external double snake shaped keyway.
