Home burglary is one of the most concerned security issues for consumers. The security door is the infrastructure of the home security. To ensure the safety of the home, it is essential to purchase a safe security door. The security of the security door mainly depends on factors such as its material, installation and door lock. Among them, the door lock is the most critical part.
At present, most consumers use A-type locks in their homes. With the development of unlocking technology, the safety of these locks has decreased. Some anti-theft locks have set the number of multi-turn turns to improve the safety of the locks, but There are more revolutions, and the A-type lock can be successfully cracked in the hands of thieves for dozens of seconds. In the near future, thieves use a new technology commonly known as “tin-paper unlocking method†to open the anti-theft lock. The shortest unlocking process can be completed in a few seconds.
The China Consumers Association reminds consumers to pay attention to the following matters when replacing the anti-theft door lock cylinder:
First, to improve the safety level of the lock only need to replace the lock core, the consumer can remove the lock core by himself, according to the specifications of the disassembled lock core to purchase the higher-level lock cylinder. Generally, the regular security door can replace the lock cylinder without replacing the whole door and the whole lock.
Second, consumers should pay attention to the model specifications of the anti-theft lock, one-to-one replacement. Generally, the B-class lock cylinder and the ordinary lock cylinder have the same shape and installation dimensions. There are also special anti-theft door locks, the specifications are not uniform, please confirm the lock core specifications before purchasing.
Third, the price of the B-class anti-theft lock core is currently in the hypermarket, which is 200~300 yuan. It is recommended that consumers buy regular brands. The same is the B-class lock, but also choose a good quality product. At present, there are many kinds of key materials, and copper or aluminum-iron alloys are easily copied. The better material is steel.
