An electronic key registration system includes an electronic key and a communication master. The electronic key transmits a registration code. The communication master receives the registration code from the electronic key, obtains key information using the registration code, and registers the key information. The registration code is set in accordance with the communication master to which the electronic key is registered. The communication master includes a level determination unit, which determines a key registration security level when the electronic key is registered to the communication master, and a registration execution unit, which obtains the key information using the registration code based on the determined key registration security level and registers the key information to the communication master.

1. An electronic key registration system comprising: an electronic key that transmits at least one registration code; anda communication master that receives the at least one registration code from the electronic key, obtains key information using the at least one registration code that has been received, and registers the obtained key information, whereinthe at least one registration code is set in accordance with the communication master to which the electronic key is registered, andthe communication master includes a level determination unit that determines a key registration security level when the electronic key is registered to the communication master, anda registration execution unit that obtains the key information using the at least one registration code based on the determined key registration security level and registers the obtained key information to the communication master. 2. The electronic key registration system according to claim 1, wherein the at least one registration code includes, among a key information generation code that serves as an origin of the key information and a check code that is used to check whether or not the key information can be generated, at least the key information generation code. 3. The electronic key registration system according to claim 1, wherein the level determination unit determines the key registration security level in accordance with whether or not registration of a random electronic key to the communication master is enabled or whether or not registration of only a specific electronic key to the communication master is enabled. 4. The electronic key registration system according to claim 1, wherein: key registration includes online registration that registers the electronic key to the communication master through network communication, andoffline registration that registers the electronic key to the communication master without using the network communication;the electronic key is either one of an offline registration electronic key and an online registration electronic key; andthe level determination unit determines the key registration security level in accordance with whether the key registration is the online registration or the offline registration. 5. The electronic key registration system according to claim 4, wherein: the offline registration electronic key stores a first registration code and a second registration code that are used as a key information generation code;the online registration electronic key stores a second registration code that is used as the key information generation code;when the key registration is the offline registration, the registration execution unit obtains the first registration code from the offline registration electronic key, generates the key information from the first registration code, and registers the generated key information to the communication master;when the key registration is the online registration and the electronic key is the online registration electronic key, the registration execution unit obtains the second registration code from the online registration electronic key, generates the key information from the second registration code, and registers the generated key information to the communication master; andwhen the key registration is the online registration and the electronic key is the offline registration electronic key, the registration execution unit obtains the second registration code from the offline registration electronic key, generates the key information from the second registration code, and registers the generated key information to the communication master. 6. The electronic key registration system according to claim 4, wherein: the offline registration electronic key stores a first registration code that is used as a check code and a second registration code that is used as a key information generation code;the online registration electronic key stores the second registration code that is used as the key information generation code;when the key registration is the online registration and the electronic key is the online registration electronic key, the registration execution unit obtains the second registration code from the online registration electronic key, generates the key information from the second registration code, and registers the generated key information to the communication master; andwhen the key registration is the offline registration and the electronic key is the offline registration electronic key, the registration execution unit obtains the first registration code and the second registration code from the offline registration electronic key, checks with the first registration code whether or not key registration can be performed, generates the key information from the second registration code, and registers the generated key information to the communication master. 7. The electronic key registration system according to claim 4, wherein: the offline registration electronic key stores a first registration code, which is used as a check code and a key information generation code, and a second registration code, which is used as the key information generation code;the online registration electronic key stores the first registration code and the second registration code that are used as the key information generation code;when the key registration is the online registration and the electronic key is the online registration electronic key, the registration execution unit obtains the first registration code and the second registration code from the online registration electronic key, generates the key information using both of the first registration code and the second registration code, and registers the generated key information to the communication master; andwhen the key registration is the offline registration and the electronic key is the offline registration electronic key, the registration execution unit obtains the first registration code and the second registration code from the offline registration electronic key, checks with the first registration code whether or not key registration can be performed, generates the key information using both of the first registration code and the second registration code, and registers the generated key information to the communication master. 8. A system capable of communicating with an electronic key, the system comprising: an electronic controller to which the electronic key is registered; andan antenna configured to obtain at least one registration code set in accordance with the electronic controller to which the electronic key is registered,wherein the electronic controller is configured to determine a key registration security level when the electronic key is registered to the electronic controller; andthe electronic controller is configured to obtain key information using the at least one registration code based on the determined key registration security level and register the key information to the electronic controller. 9. An electronic key registration system comprising: an electronic key that transmits at least one registration code; andan electronic controller that receives the at least one registration code from the electronic key, obtains key information using the at least one registration code that has been received, and registers the obtained key information in a memory, whereinthe at least one registration code is set in accordance with the electronic controller to which the electronic key is registered,the electronic controller determines a key registration security level when the electronic key is registered to the electronic controller, andthe electronic controller obtains the key information using the at least one registration code based on the determined key registration security level and registers the obtained key information to the electronic controller.
