Door locks are essential items in daily life. After thousands of years of development and many changes, with the support of intelligent technology, smart door locks are gradually entering thousands of households. For example, in the way of unlocking, people in and out of their families use fingerprints to open the door, and parents and sisters in their hometown come to the remote APP to open the door. Renters have temporary passwords, password access doors, card access doors, emergency situations, and mechanical keys to respond to different needs at any time. The security of smart locks is higher. We all know that the level of lock cylinder determines the safety of a lock. Among them, the A level lock cylinder has the lowest safety, with a thief being able to unlock in just one minute, and the C level lock cylinder has the highest safety. Even with professional tools, it takes 270 minutes to unlock. Both intelligent and mechanical locks can be replaced with lock cylinders, so there is no comparison in this regard. However, smart locks have multiple alarm functions such as remote monitoring, anti technology activation alarm function, and anti violence activation alarm function, so smart locks are more secure. So when choosing a Smart Lock, pay attention to: 1. Select C-level anti-theft alarm lock cylinder The C-level lock cylinder has the highest safety performance, taking 270 minutes to unlock. It also has functions such as identifying non original keys and reminding of forgotten keys. 
2. Select semiconductor biometric fingerprint head
Smart locks with low security levels can easily open the door with copied fingerprints, while semiconductor recognition locks must use live fingerprints to open the door. 3. Select zinc alloy material
Among the smart lock panel materials, zinc alloy material is easy to shape and have a beautiful appearance in production, and has a relatively long service life, which is also environmentally friendly and free of formaldehyde; Secondly, it is made of aluminum alloy material.
