When you order a product from CISM for the first time, we will assign you an individual proof of ownership card. This card makes you the sole holder of the rights to manage and reproduce the variations associated with the products (keys, cylinders, locks, etc.).
The proof of ownership card contains a masked confidential code that must be specified for any subsequent duplication orders after the first one.
As a result, duplication of your products is completely impossible anywhere other than in our facilities, and you are protected from unauthorized or illegal duplication, which is common with “traditional” keys. The mechanism present in your locks and keys, as well as the associated coding, can only be duplicated by our technicians in the workshop.
