To prevent a registered electronic key from being copied, to thereby improve security.SOLUTION: A vehicle control device 10 causes a display portion of a vehicle 50 to display a PIN code (first identification information) in a registration mode. A user inputs the PIN code to a portable machine 30, and reads a bar code 29 (second identification information) of a FOB 20 (a first electronic key) by the portable machine 30. The portable machine 30 uses the PIN code and the bar code to generate an encryption key Y (second encryption information) common to the portable machine 30 and the vehicle control device 10, performs prescribed calculation on the basis of the encryption key Y, and transmits a result of calculation to the vehicle control device 10. The vehicle control device 10 determines whether the calculation result received from the portable machine 30 is correct or not and when a result of calculation is correct, registers the portable machine 30 as a second electronic key by storing the encryption key Y.SELECTED DRAWING: Figure 1

    【課題】登録済の電子キーが複製されるのを防止して、セキュリティ性を向上させる。【解決手段】車両制御装置10は、登録モードにおいて、車両50の表示部にPINコード(第1識別情報)を表示させる。ユーザは、携帯機30においてPINコードを入力し、続いてFOB20(第1電子キー)のバーコード29(第2識別情報)を携帯機30で読み取る。携帯機30は、PINコードとバーコードとを用いて、携帯機30と車両制御装置10に共通の暗号キーY(第2暗号情報)を生成し、この暗号キーYに基づき所定の演算を実行して、その演算結果を車両制御装置10へ送信する。車両制御装置10は、携帯機30から受信した演算結果の正否を判定し、演算結果が正常であれば、暗号キーYを保存することにより、携帯機30を第2電子キーとして登録する。【選択図】図1
