Police Tip: Please pay attention to the authenticity when installing the B-level lock

The lock core is the heart of the anti-theft door. No matter how many lock points the anti-theft door has and how strong the door is, as long as the lock core is opened, the last line of defense will be lost. At present, the vigorously promoted B-class lock cores certified by the Ministry of Public Security increase the difficulty of technical unlocking, effectively reduce drop-in technology to unlock burglary cases, and better protect the life and property safety of the people.

A few days ago, the Public Security Prevention Brigade of the Public Security Management Detachment of the Dalian Municipal Public Security Bureau discovered that a "cottage" lock core appeared during the visit. Door locks are the most important for families to prevent theft. When residents install Class B locks, how to identify the authenticity and protect their rights and interests, the police remind you to do "four must see":

One is to look at certification. Regular B-level locks are certified by the Technical Inspection Center of the Ministry of Public Security, with anti-technical opening function, and are highly secure locks.

The second is to look at the structure. The B-level lock cylinder is mainly a blade side cylinder lock cylinder, which is different from the straight-line and cross-shaped lock cylinders with lower anti-theft levels. Open. The B-level lock key is a flat plate type, and the key slot is a single-sided or double-sided two-row concave plus S-type, or an internal and external double-snake type internal milling slot structure.

The third is to look at the price. To buy locks of regular brands, most of the obviously low prices are counterfeit products. It takes a few seconds to open technically. It does not have anti-theft function, so try to choose good quality products. It is especially important to note that most of the current keys are easy to be copied. Residents should take care of them, do not expose their keys in front of others, and enhance security awareness in daily life to prevent the keys from being easily copied.

The fourth is to look at qualifications. When installing locks, look for regular lock repairers who are registered in the industry and commerce and filed with the public security. They should check the business license of the unit, whether they hold the registration certificate issued by the public security organ, check the ID card of the employee, and wear the public security system Issued a lock repair service card. Practitioners should issue invoices to consumers and the "Triple of Locks Repair Registration" printed by the public security organs.

In the future work, the public security department will further increase the inspection efforts. If the public finds a problem with the lock, they should also report it in time. The police and the people work together to maintain the good order of lock management and create a safe and harmonious home.
