One-word lock cross lock is not anti-theft

Police warning

This year, the police officer He Shuwu and his attack team at the Donghua City Police Station in Dongcheng City arrested a total of 21 thieves. He told the Legal Evening News that 80% of the cases of using technology to unlock burglary were single-word locks, and thieves often used a tin foil to easily open the door.

"To unlock the scribe, as long as you screw a key more. In the face of technology unlocking, the public only has to replace the one-word lock with low anti-theft coefficient." He Shuwu said.

The reporter learned that according to the Ministry of Public Security GAT73-94 mechanical anti-theft lock regulations, the lock of the general protection level is indicated by the letter "A", and the lock of the advanced protection level is indicated by the letter "B". He Shuwu reminded the public that the public can remove the lock cylinder and purchase a higher-level lock cylinder according to the specifications. "Generally, regular security doors can be replaced with lock cylinders, eliminating the need to replace the entire door and lock."

Case analysis

High incidence area

The old community and the urban-rural combination have a high rate of crimes. "And these communities are generally poorly closed, and the doors and windows are old and easy for the thief to commit crimes."

Crime time

The two periods of the most burglary are the morning and afternoon. These two periods also correspond to two different methods of burglary: one is the unlocking of the pick, and the other is the technical unlocking.

Case method

1. Picking up the lock: It is very simple. The thief uses the plastic sheet to make the picks from the door seams. Those who simply touch the lock tongue without the lock are open and can be opened with a single stroke.

The picking of the picks mainly occurred in the early hours of the morning. Using the luck of everyone who thought that there was no need to lock the door at home, the monks fell asleep and committed crimes. The thief is mainly aimed at the "floating money" in the living room - mobile phones, laptops, bags at the door, and so on.

2. Technology unlocking: Thieves often use the "one-word lock", "cross lock", "tin paper", "key blank" and other tools to open the security door lock into the room for theft.

It usually happens in the afternoon, first knock on the door to confirm whether there is someone in the house. After the person is confirmed, use the tool to open the door to steal. This kind of theft is not only for floating money, it is often rummaging, cash and jewelry are the main targets.

Do you change your lock at home?

Class A anti-theft lock: mainly has a word key and a cross key. The internal structure of the A-class lock cylinder is very simple, limited to the change of the marble, the marble groove is small and shallow, and the mutual opening rate is extremely high.

The tin foil unlocking is mainly composed of a word lock and a cross lock. Since the toughness of the tin foil can be deformed in the lock body with the teeth of the pin lock teeth and bite on the tooth, the door lock can be quickly opened. "The thief can open the A-level lock in a few seconds, and the shortest is only a few seconds." He Shuwu said.

Class B lock: flat key, with double row of marble slots, the difference with the A-class lock is that the key surface has a row of curved and irregular lines. The B-level lock is relatively difficult to open, because the time to open the B-level lock is higher than the thief's criminal psychological endurance. If the thief can't open within one minute, it will change to another, reducing the chance of being discovered.

Super B-class lock: The key shape is a single-sided blade inner milling groove or an outer milling groove. The lock core type is a side column lock cylinder, and the mutual opening rate is extremely low. If the tool is opened, the lock cylinder will be destroyed and it will not open. There is also a Class C lock similar to a premium car key that can be used by citizens to improve the level of family protection.
