发明名称 Electronic key registration system
摘要 An electronic key registration system includes an electronic key device that stores a key ID and a first piece of information. A controller is arranged in a communication subject. A registration tool writes the key ID to the controller and stores a second piece of information. Encrypted communication between the communication subject and the electronic key device is enabled after the key ID and a corresponding encryption key are written to the controller. An information center, which communicates with the registration tool, receives and compares the first and second pieces of information. The registration tool is permitted to write the key ID when receiving a signal from the information center indicating that the first and second pieces of information conform to each other.
