The lock cylinder is the main part that controls the opening of the lock, and is the heart of the lock. Therefore, the lock cylinder is very important. When we buy a lock, we must pay attention to the choice of the lock cylinder. So how to choose the lock cylinder?

1. Choose a regular big brand
Generally, the big brands have a long time to make lock cylinders, have a good reputation, and the quality is generally stable. Small brands are unstable and the quality is uneven.
2. Look at the material of the lock cylinder
It has been proved by practice that brass is the most suitable material for the lock cylinder, which has the characteristics of corrosion resistance, invariance, and smoothness with use. Of course, brass is also divided into good and bad, depending on the weight, the heavier the better.
3. Look at the structure
At present, the highest anti-theft structure on the market is the C-class anti-theft lock cylinder. There are so many lock cylinders, but the structure is complicated. Many cheap lock cylinders are either unusable or cut corners, which are unreliable.
