Direct digit code and indirect code

The two most common key codes used by lock manufacturers are the direct digit code and the indirect code.

A direct digit code represents key cuts based directly on a numerical sequence corresponding to different depths of the cuts made into the key. This allows for straightforward interpretation and duplication of keys as it is governed by a specific, easily understood system.

In contrast, an indirect code system is more complex and represents key cuts based on a predetermined table or at a specific location for cutting. This system can require additional processes to interpret the code correctly, as it does not provide a direct correlation to the key’s physical cuts.

Understanding these two codes is crucial for locksmiths, as it allows them to effectively work with a variety of locks and keys, ensuring they can replicate and manage security mechanisms accurately.
