So how do you tell the quality of the lock when you choose the lock? Remind to pay attention to the following points:
First, look at the key. First of all, see if the processing trace of the key is smooth, the surface of the key is smooth, and there is no trace of manual processing. Secondly, if the structure is complicated, there are at least three kinds of anti-theft structures. For example, the key has a cylindrical shape on both sides, a multi-point concave keyhole, and a plurality of concave key grooves or curved concave key grooves.
Second, look at the lock core. Align the lock cylinder with the light source, and the inside of the lock cylinder is clean and tidy.
Third, the weight of the 。. The heavier the weight, the better the quality of the lock cylinder.
"There is no lock that can't be opened in the world. The so-called security level is divided according to the time required for a professional unlocked person to open the lock. "You can't change your lock and feel that everything is safe, or you should develop a good anti-theft awareness. For example, the door is fully locked, and when it is home, it is locked. â€
