The key shape of class C lock is single-sided blade inner milling slot, outer milling slot key or double-row + blade, the lock core type is side column lock core, and the marble structure is double-row blade plus V-shaped side column lock. If the lock cylinder is opened with a strong twisting tool, the inside of the lock cylinder will be damaged and locked by self-explosion, resulting in the failure to open.

In addition, a good smart lock adopts a semiconductor capacitive fingerprint head, so that living fingerprints can be identified and unlocked, and there is no possibility that fingerprints can be copied and unlocked. Some smart locks also have networking monitoring function, which can monitor the status of switch locks on APP at any time, and once someone opens the door, they will receive a prompt message.

2) Fingerprint head

There are two kinds of fingerprint heads of fingerprint lock: optical fingerprint head and semiconductor fingerprint head. Generally speaking, the price of semiconductor fingerprint head is higher than that of optical fingerprint head, and the recognition rate of semiconductor fingerprint head is better than that of optical fingerprint head.

The main materials of fingerprint lock body are stainless steel, zinc alloy and iron. The lock body structure is made of pure stainless steel, and its mechanical strength and stability are much higher than those of alloy locks popular in the market at present.
