Mechanically

The mechanically programmable locking system:

If a key is lost, only the keys for that specific lock need to be disposed of and replaced with new keys. The cylinders are then reprogrammed using the "old" and "new" red keys. There are 77,824 different lock combinations possible.

The key feature of this system is that the cylinders can be reprogrammed with a different lock combination.
As a result, the cylinders never need to be replaced, and expensive interchangeable cores are not required. It also simplifies inventory management since all cylinders are "identical."
Since keys can only be reordered with the presentation of a security card and due to the unique round shape that cannot be copied with standard key-cutting machines, the locking system is considered very secure.
The mechanism inside the cylinders is highly robust as it eliminates traditional pins and springs. The special mechanism provides excellent protection against "traditional" lock-picking techniques.
This system is more cost-effective to acquire compared to systems with interchangeable cores, and in the event of key loss, it is much cheaper
as only the keys need to be replaced, which are available at a low cost compared to other systems.
