Anti-theft door selection lock cylinder

First, look for the key to the door lock. The more and deeper the "teeth" of the key, the more complicated the arrangement of the door lock is, and the more difficult it is to open.

Second, look at the color of the door lock. The door locks of good quality are all processed by electroplating, and the gloss and smoothness are very good. If the color is dark yellow, it should be copper core. This material is relatively strong, so the protection is better.

Third, look at the weight of the door lock. The heavier the weight, the better the material of the lock cylinder, the better the quality of the lock cylinder, the more beads in the lock cylinder, the better the protection performance of the lock.
