During the use of the lock, the plug is not smooth regularly (half a year or once a year) or when the key is not smooth, and no liquid petroleum materials such as gutter oil are used as lubricant and spring, so as to avoid that the lock cannot be opened due to the oil rod. You can use a household pencil to apply the pencil to the key, and then insert the lock cylinder several times to lubricate the function. In addition, professional lubricating oil and antirust agent can also be used. Some zinc alloy and copper locks will be found to have & quot; spots & quot; after long-time installation on the door. This phenomenon does not belong to rust, but belongs to oxidation. If it happens, the new station area will unlock and repair locks. For the maintenance of locks, the spots can be removed only by spraying wax on the surface. The first trick to choose a lock is to buy the lock key's teeth;. The more teeth, the deeper the teeth, the more complex the arrangement, the greater the difficulty and the better the anti-theft performance. Second: the lock theory is two, one is larger than the weight of the lock. The heavier the weight, the better the lock quality, the more beads in the core, the better the anti-theft function. Third: choose the lock cylinder to see the color, compare the color to see the work. The quality lock cylinder is electroplated, with smooth surface and bright color. The color of dark yellow is copper core, strong, with good anti-theft performance. The color of lock core is dark, and the color of gray with bubbles is zinc alloy, with general anti-theft performance. The fourth: insert the key to lock the anti-theft performance is poor. After the key is inserted, continue to press the key to lock the key clockwise or anticlockwise to lock the anti-theft performance is poor. The smooth state is poor, and the anti-theft effect of the rotary lock is good. Grade one lock currently has a security lock key with a key and a cross key. The internal structure of class a lock cylinder is very simple, only limited to the change of marbles, while the slot of shrapnel is small and shallow.

The shape of super class B lock is like a single-sided blade with groove or outside milling key. The core type is the side post lock cylinder.
