Introduction to the classification of grades:

1. Lock core standards for anti-theft door locks

The country divides anti-theft door lock cores into three levels: A The first-grade lock cylinder is relatively primitive and the most unsafe. A skilled person can open it very quickly by taking advantage of the fact that some owners' keys are flat or have cross keys. It can take less than two or three minutes at the fastest. Level B is a relatively safe level lock cylinder. The key is double-sided and double-row. Even if a skilled person has the tools, it will take about 10 minutes to open it.
