A key can open more locks, cheap locks, "inter-opening rate" is much higher than international

Single lady Ms. Huang was alone in the rental room to take a nap. Suddenly a drunken man opened the door with a key and came in. She suddenly screamed and screamed. The man lived on the 7th floor, and Miss Huang lived in 6 On the floor, the man remembered the wrong floor after drinking, just as the landlord used the same brand and model of the door lock in all the rooms of the building, thus staged this false alarm. It is understood that the standard set by the state for lock manufacturers is “inter-opening rate” less than six ten thousandths. Exceeding this standard is considered as a non-conforming product.

Frightened: drunkard breaks into single woman room

Ms. Huang is a real estate company employee in Dashatian, Nanning City. She rents a 7-storey private residence near Yinshacai City, Jianxin Road. Yesterday, Miss Huang was lying in bed for a nap, and suddenly heard the sound of a key to turn the door lock. Before she had returned to God, a young man with a slap in the air opened the door and screamed in, and Miss Huang suddenly screamed.

When I heard Miss Huang call for help, the landlord and the tenants rushed over. At this point, the drunken man refused to drink, and when he left the room, he apologized to Miss Huang, claiming that he had drunk a few cups at noon and opened the wrong door. Miss Huang insisted on calling the 110 police. Fortunately, the landlord arrived in time to confirm that the man was indeed a tenant living on the upper floor of Miss Huang. He had just moved in less than a month.

After learning that the drunken man did not intend to break into it, everyone focused on Miss Huang’s door lock and key. The landlord took the key from the drunken man and found that he personally handed it to him.

The landlord took the key and inserted it into the keyhole of Miss Huang’s door. The door lock was really opened. The landlord took the key to the room where the drunk man rented, and opened the door easily. The original landlord used the same brand and model of the door lock when decorating the building. The two keys and the lock "crash".

In the end, the landlord apologized to the drunken man and Miss Huang respectively, and agreed to fund the replacement of the new lock for the two.

Why can a key open two door locks at the same time? With this question, the reporter interviewed Zhou Jie, who has a lock shop at No. 14 Dongfeng North Road, Dashatian.

Reason: the cheap opening "opening rate" is much higher than the national standard

Upon hearing the reporter's intention, Zhou Jie replied to the reporter that the same lock factory produced a large number of locks every day, but it could not be equipped with only one set of key molds for each lock, so there was a “inter-opening rate”. According to Zhou Jie, the “inter-opening rate” standard set by the state for lock manufacturers is less than six ten thousandths. Exceeding this standard is unqualified.

Because of the cheapness of the greed, many citizens like to buy cheap locks produced by small factories. The "inter-opening rate" of these locks is usually much higher than the national standards, especially some padlocks, often as high as one percent or even one-tenth. .

The reporter then went to a lock shop in Dongfeng Road. I saw that the counter was filled with padlocks of different sizes. One box (10 packs) was padlocked by Kelly brand produced by Mingguang Lock Factory in Pujiang County, Zhejiang Province. The reporter immediately opened one and tried to open the other five new locks with the key. I didn't expect one of the locks to be opened easily.

Seeing this situation, the store owner was a little embarrassed and joked: "Tonight, the two-color ball draws, you can go buy the lottery."

Reminder: People should be cautious when purchasing locks

What kind of key can open multiple door locks? The reporter took the problem to visit the market. The area around Renmin Road in Nanning is a concentrated area for locks and stores. Various brands of security doors and locks are available in various sizes, ranging from tens of yuan to hundreds of yuan.

In one of the lock stores, the owner, Mr. Xu, said that in the hands of professionals, the lock of the word and the cross was opened in a few seconds. If it is a simple or poorly crafted lock, it can be opened with the same type of key. . The crescent lock and the cross lock are relatively difficult to open. After that, he took out a key word and opened several locks one after another.

Zhou Jie told reporters that this kind of key is called the "universal" key, which is caused by the difference in the control of the various locks in the production process. However, many people are unaware of it, and when they are used, they are unintentionally discovered. If they are mastered by criminals, the consequences are unimaginable.
