Locking Systems & Security Cylinders

When securing a building with mechanical locking cylinders, there are generally two system types:
Either all doors are configured to be keyed alike – meaning one key opens all doors – or the system is structured hierarchically, so that some keys open more doors than others.

System Structure

Hierarchically organized master key systems can be designed in various ways.
The most well-known configuration is the General Master Key System, where:

Onemaster key opens all doors
Group keysopen selected areas
Individual keysopen only a single door

This classic system is commonly used in commercial buildings and institutions, where each keyholder has access only to predefined zones – and access can only be extended with a new key assignment.

Whatever your requirements may be, BEWENG Security can meet them with:
