With the improvement of the residents' awareness of anti-theft, everyone pays more and more attention to the quality of the locks during the decoration. Sometimes, for a lock, it costs thousands of dollars. The figure is to have a more secure sense of security in the home life. In fact, for the room security, the choice of a good lock is only half of the completed project. As the use time increases, a good lock will be greatly reduced if it is not scientifically maintained.
If the door lock switch is not smooth during use, it should be sprayed on the oblique tongue in time to avoid damage caused by forced friction. When the key is inserted into the keyhole, it is necessary to spray some lubricating oil into the keyhole. It should be noted that the lubricating oil should not be too thick. Be careful not to insert the key with water on the surface, as this will cause the spring inside the lock to rust. Also remember not to open the door directly with the key. After the key is turned to the door lock, the key can be directly opened by opening the key without returning to the original position, which will seriously shorten the service life of the lock. In fact, in daily life, for the sake of convenience, it is extremely common for residents to use keys as handles, so that everyone has become numb to this wrong approach.
