It is well known that expired food can cause harm to the body. But, you know what? The locks at home will expire. Once the shelf life has passed, it will cause us unpredictable danger just like food. Look, is your lock core expired?
Door locks should be changed every five or six years.
Recently, when the reporter visited some unlocked shops, the unlocking master said: "The locks bought by ordinary consumers will wear out after a long time, and they are easy to be opened by keys with similar teeth shape." But it is often difficult to find out for oneself that in life, as long as the lock is not damaged, it is not necessary to replace it. This is not the case. It is understood that the warranty period of ordinary door locks is only five or six years.
Nowadays, many burglar-proof doors and locks in our residential areas are purchased and installed by real estate developers. Most of these locks are Class A locks, with low safety factor and shorter shelf life.
"I once went to the wrong unit, but opened the door of other people's house with my key. What's the matter?" said Ms. Liu, who lives in a residential district of Xisanhuan in Zhengzhou, who uses the same type of lock in the same district. In theory, the probability of "opening several locks with one key" is very high. In addition, if the lock core is not replaced for a long time, there will be potential safety hazards. Only by changing the lock core in time can the safety factor of living environment be improved.
It's New Year's Day. Some problems should be paid attention to.
To celebrate the New Year, whether it's visiting relatives, friends'gatherings, or traveling, buy yourself a "sense of security". How to protect our "home"? Let's change the super B lock core. In addition, the reporter also summarized some common sense of anti-theft, hoping to be useful to you.
Firstly, we should choose reliable anti-theft door: the manufacturer should have a production license issued by the relevant departments, product specifications and models that are qualified after testing (with testing reports), and the sales unit should have a sales license issued by the relevant departments. Be careful not to try to buy "three no products" cheaply.
Secondly, when installing, we should adhere to "tailor-made clothes", pay attention to the close cooperation between the door and the hole, the screw should be welded to death, and it is strictly forbidden to install flat-pat external hanging type.
Thirdly, after the key is lost, the original manufacturer should be asked to change the lock in time to prevent the bad people from using it.
Finally, once the door lock breaks down, it should be repaired in time, which is not suitable for use and gives the bad guys a chance.
