Реферат: This invention relates to a physical key (100) for provisioning a communication device (101) with data allowing said communication device (101) to access a vehicle resource by operating remotely a vehicle lock system (130) in which a first cryptographic key called master key is stored, comprising a secure enclave also storing the master key, the physical key being configured to: establish a communication link (110) with the communication device (101); derive by the secure enclave a second cryptographic key called derived key from the master key; transmit to the communication device (101) via the secure communication link (110) the derived key for enabling the communication device (101) to answer a security challenge from the vehicle lock system (130) and the vehicle lock system (130) to verify said answer, the access to the vehicle resource being allowed if the answer is successfully verified.
