An infrastructure to obtain a copy key of a key, comprising:
- a first device associated or provided with a detection system of characteristic parameters of the key;
- a remote unit in which, in an organized manner, for each key acquired by the detection system, the characteristic parameters identified by the detection system or corresponding operating instructions necessary for obtaining the characteristic parameters are memorized;
- a second device configured to manage, check, or control a start of a step, in which the copy key is to be obtained, the second device being portable and managed by a user, who is an owner or a manager of the key to be acquired in the remote unit or by the user who wants to obtain the copy key of the key already acquired in the remote unit;
- a third device, which communicates with the second device and/or with the remote unit, the third device being configured to receive the operating instructions of the key, of which the copy key is to be obtained, the third device being located at a duplication center and being managed by the duplication center;
- a key duplicating machine, which is provided with or associated with the third device, to create the copy key based on the operating instructions received by the third device;
- and
- a first software module configured to:
- authorize the third device to receive and use the operating instructions to create the copy key, and
- removing or deleting automatically from the third device, as soon as the copy key has been obtained from the duplicating machine, the operating instructions previously received from the third device and used by the duplicating machine to create the copy key,
- wherein:
- the first software module configured to authorize the third device to receive and use the operating instructions comprises a software loaded and executed in the remote unit, a second software module is loaded and executed in the second device, and a third software module is loaded and executed in the third device, the first, the second, and the third software module being configured to interact so as to implement a procedure for authorizing the third device to download and to use the operating instructions for obtaining the copy key of the key that has already been acquired, and
- the third software module of the third device is configured to never visualize entirely on a display of the third device and/or of duplicating machine data related to the operating instructions to be supplied to the duplicating machine to obtain a particular encryption.
