Chengdu, Sichuan News Network, December 20 (Yang Yang reporter Leizi) Longmou is a person with a criminal record of theft. He was released from surveillance by Dujiangyan police on June 19 this year. After returning to freedom, Longmou still did not repent, thinking that burglary was a way to make money, so he used some learned unlocking techniques to sneak into Songpan County, Barkam City and other places in Aba Prefecture to carry out burglary. He was arrested by Marcand police after two consecutive burglaries in Malcolm.
On December 2, two families in Malcolm were stolen continuously on the same day. Strangely, the doors and windows of the victim’s home were not damaged, but the gold and silver jewelry and cash totaling more than 20,000 yuan at home were gone. After receiving the alarm, the Malcolm City Public Security Bureau quickly organized forces to carry out the detection work.
The criminal suspect Long Mou identified the scene.
After a large number of interviews, investigations, image screening and other work, the police handling the case finally locked the identity and activity track of the suspect after 16 days. After learning that the suspect appeared near a residential area in Dujiangyan, at 20 o’clock on December 18, the police handling the case arrested him with the cooperation of Dujiangyan police.
After investigation, the 29-year-old suspect, Long, came from Ziyang. He was idle on weekdays, but he learned the skill of unlocking unintentionally. After Long’s own confession, he committed burglary in Songpan County and fled to Malcolm City. On December 2 nd, through the early observation, Long locked the target of the crime into a certain community in Malcolm City. When the victims Xu and Su were not at home, they used their own tools (two wires) to unlock the lock and then carried out the theft.

Hurry home and see what kind of lock cylinder your home is.
List of all kinds of keys
Marcand police said that the low security level of the stolen door lock cylinder gave criminals an opportunity. The police reminded that it is an extremely important way to prevent theft and upgrade the security level of the door lock cylinder. So, what are the common lock cores and keys? The police made a simple comb, which may help you to some extent.
A
At present, there are mainly one-word keys and cross keys for Class A anti-theft locks on the market. The internal structure of Class A lock core is very simple, which is limited to the change of marble, and the marble grooves are few and shallow. The anti-technical opening time is within 1 minute, and the mutual opening rate is extremely high. The marble structure is single-row marble or cross lock.
Once, relevant people in the industry did experiments on the spot, and it took 41 seconds to open the locks of residents’ homes, which is what we call class A locks.
After a large number of investigations, it is concluded that 90% thieves will give up voluntarily if they fail to open the lock within one minute, while thieves can usually open the A-class lock in more than ten seconds, so the safety factor of the A-class lock is low.
Unlocking time of Class A lock core: professionals can open it within 30 seconds. Unable to upgrade.
B
The key of Class B lock is a flat key with double rows of marble grooves, which is different from Class A lock in that there is a row of crooked and irregular lines on the key face. There are three main types of lock cores: computer double-row lock core, double-row crescent lock core and double-sided blade lock core. The anti-technical opening time is within 5 minutes, and the mutual opening rate is high. The lock cylinder can be opened within 1 minute by strong twisting tool.
Unlocking time of B-class lock core: professionals can unlock it for more than 5 minutes and less than 120 minutes.
C
At present, the safer lock core on the market is the C-class lock core, which adopts the patented key of double row, computer and compound curve groove, and cannot be opened technically in 270 minutes.
Unlocking time of Class C lock core: It takes professionals more than 240 minutes to open it.
The three levels of unlocking time are different. The longer the time, the higher the safety factor and the lower the possibility of theft. The police reminded that the year is approaching, and the anti-theft at home cannot rely solely on the security door. At home, we should still pay attention to some anti-theft details in life. For example, it is best for a person to lock the security door at home and close the doors and windows when sleeping at night, so that the probability of theft at home is correspondingly much smaller.
