Duplication means for an electronically coded key and related method
First Claim
1. A method for the duplication of original electronic keys, comprising:
- intercepting a radio-electric interrogating signal of an encrypted electronic authentication system transmitted between a central processing unit of a vehicle and an original key, the radio-electric interrogating signal including therein an encrypted random code generated by an algorithm, the encrypted random code including therein a secret code, the encrypted electronic authentication system utilizing an identification code (ID), the secret code, a password, and the algorithm;
transferring said intercepted random code to a key duplicating device;
decrypting said secret code from said random code at said key duplicating device;
performing an interrogation process by transmitting a radio-electric signal, including said secret code, from said key duplicating device, to said original key;
receiving the password, transmitted by said original key, at said key duplicating device in response to the transmission of the secret code;
transferring said password to a blank key, the blank key including the algorithm and a data storage device configured to store an identification code (ID), a secret code and a password.

Abstract
A method for the duplication of original electronic keys used in the road vehicle transport sector provided with coded and encrypted electronic authentication. The method including the steps of intercepting a radio-electric interrogating signal of an encrypted electronic authentication system transmitted between a central processing unit of a vehicle and an original key, decrypting a secret code from a random code at a key duplicating device, performing an interrogation process by transmitting a radio-electric signal including said decrypted secret code from said duplicator, to said original key, receiving a password, transmitted by said original key, at said duplicator in response to the transmission of the secret code, and transferring the password to a blank key.

7. 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. - View Dependent Claims (8, 9)

10. 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. - View Dependent Claims (11, 12, 13, 14, 15)
