1. A method for registering an electronic key to a controller of a vehicle, wherein the electronic key includes a unique electronic key ID and an encryption code associated with the electronic key ID and used for encrypted communication between the electronic key and the controller, the method comprising:
performing an area-limited registration in which the electronic key is registered within a limited area; wherein the area-limited registration includes: reading a SEED code and the electronic key ID from the electronic key and writing the electronic key ID to a memory of the controller; inserting the SEED code in an encryption code computation equation to generate the encryption code with the controller and writing the encryption code to the memory of the controller; deleting the SEED code from the electronic key after writing the encryption code to the memory; invalidating a function for the area-limited registration in the controller; assigning a unique vehicle ID to the vehicle; and associating the vehicle ID, a controller ID, which is unique to the controller, and the electronic key ID with one another in a database of a management center.
