Duplication means for an electronically coded key and related method
First Claim
1. A method of duplicating a motor vehicle electronic key, comprising:
- transmitting to the motor vehicle electronic key, by a first device, an encrypted secret code;
receiving, by the motor vehicle electronic key, the encrypted secret code;
as the electronic key is receiving the secret code which has been encrypted, intercepting the transmission to the motor vehicle electronic key by the first device, comprising the encrypted secret code, and storing, by a second device different from the first device and different from the motor vehicle electronic key, the encrypted secret code, which is extracted from the transmission;
interrogating the motor vehicle electronic key, by a duplicator device which is different from the first device and different from the motor vehicle electronic key, using the encrypted secret code which has been intercepted and stored;
receiving, by the duplicator device from the motor vehicle electronic key, a password transmitted from the motor vehicle electronic key in response to the interrogating;
storing, by the duplicator device, the password transmitted from the motor vehicle electronic key;
transmitting, by the duplicator device, the password to a blank key; and
storing the password in the blank key.

Abstract
Method for the duplication of original electronic keys used in the automotive transports, and provided with coded and encrypted electronic authentication means, comprising: an Identification Code (ID), an encrypted secret code, a Password, an algorithm, data storage and computing means, able of being used in vehicles provided with a central processing unit able of storing an Identification Code (ID), an encrypted secret code, a Password, an algorithm, said duplication method being able of obtaining a duplicated key based on a blank key, which is originally provided with an algorithm, data storage means able of storing said Identification Code (ID), said secret code and said Password, wherein said data storage means are initially empty; said duplication is based on a duplication means and on a method which allows of using the blank key as intercepting means of secret codes sent by the vehicle central processing unit, and of transferring said information to the duplication means itself.

7. A system for duplicating a motor vehicle electronic key which operates when there is a transmission to the motor vehicle electronic key, by a first device, an encrypted secret code and when there is a receiving, by the motor vehicle electronic key, the encrypted secret code, the system comprising:
-
a receiver which, as the motor vehicle electronic key is receiving the encrypted secret code, intercepts the transmission to the motor vehicle electronic key by the first device, comprising the encrypted secret code, and stores the encrypted secret code, which is extracted from transmission; a transmitter, which is part of a duplicator device and different from the first device, which interrogates the motor vehicle electronic key using the encrypted secret code which has been intercepted and stored; a receiver, which is part of the duplicator device, which receives from the motor vehicle electronic key, a password transmitted from the motor vehicle electronic key in response to the interrogating; a memory, within the duplicator device, which stores the password transmitted from the motor vehicle electronic key; a transmitter, which is part of the duplicator device, which transmits the password to a blank key. - View Dependent Claims (8, 9, 10, 11)
