Duplication means for an electronically coded key and related method

A method for the duplication of original electronic keys, comprising:

• intercepting, via an interception device placed in proximity to an original key, at least one radio-electric signal containing an identification code (ID) and an encrypted random code and storing the intercepted identification code (ID) and the encrypted random code in a storage of the interception device, the radio-electric signal being generated by an electronic authentication system of a vehicle performing authentication by
• transmitting, by a processing unit and in response to the activation of a central processing unit, the radio-electric signal including an identification request for the identification code (ID) of the original key, to the original key,
• transmitting, from the original key, the identification code (ID) stored in the original key to the central processing unit,
• comparing, at the central processing unit, the identification code (ID) with a previously stored corresponding ID code, and
• in response to a positive result from the comparing, generating, at the central processing unit, a random code encrypted by the algorithm, which includes the secret code, and sending the random code to the original key;
• transmitting, from interception device to a duplicator device, the intercepted identification code (ID) and the encrypted random code;
• and
• decrypting, at the duplicator device and using a series of mathematical functions and calculations, said encrypted secret code from the encrypted random code.

A method for the duplication of original electronic keys, comprising:

• a) interrogating an original key by transmitting a radio-electric signal from a key duplicating device to the original key inserted into the key duplicating device;
• b) receiving a radio-electric signal from the original key containing an identification code (ID);
• c) storing said identification code ID into a blank key;
• d) receiving, at the blank key, in response to an attempt at ignition from the blank key inserted into a vehicle lock of a vehicle, and from a central processing unit of the vehicle, a radio-electric signal containing an encrypted secret code;
• e) decrypting, at the key duplicating device, the secret code via computing and mathematical functions;
• f) interrogating, at the key duplicating device, the original key with a radio-electric signal containing the secret code in order to emulate vehicle operation;
• g) receiving, at the key duplicating device, a passcode from the original key in response to the interrogating;
• h) transmitting, from the key duplicating device to the blank key, the passcode and the secret code;
• and
• i) storing, into a defined memory of the blank key, the passcode and the secret code.
