To allow operation such as lock/unlock of a vehicle key to be controlled via a mobile terminal such as a smart phone.SOLUTION: A vehicle control system includes: a control server 130 capable of communicating with a mobile terminal 110 of a user of a vehicle via a network line 120; and a control device 140 configured using a base plate of a remote control key that locks/unlocks a vehicle key and for controlling operation of the vehicle. The control server 130 encrypts control data to control operation of the vehicle by using ID of the vehicle and a secret key associated with the ID, and transmits the control data after encryption to the mobile terminal. The mobile terminal 110 transmits the control data after encryption transmitted by a wireless communication unit to the control device 140 by using short-range wireless communication. The control device 140 decrypts the control data after encryption transmitted via the mobile terminal 110, and when a onetime password (OTP) included in the control data matches a onetime password stored, performs a command included in the control data, and when it does not match, does not perform the command.SELECTED DRAWING: Figure 3 【課題】スマートフォンなどの携帯端末を介して車両の鍵のロック／アンロックなどの動作が制御できるようにする。【解決手段】車両の使用者の携帯端末１１０とネットワーク回線１２０を介して通信可能な制御サーバー１３０と、車両の鍵をロック／アンロックさせるリモコンキーの基板を利用して構成され車両の動作を制御する制御装置１４０と、を有し、制御サーバー１３０は、車両のＩＤとＩＤに対応付けた秘密鍵とを用いて車両の動作を制御させる制御データを暗号化し、暗号化後の制御データを携帯端末に送信し、携帯端末１１０は、無線通信部が送信した暗号化後の制御データを、近距離無線通信を用いて制御装置１４０に伝送し、制御装置１４０は、携帯端末１１０を介して伝送された暗号化後の制御データを復号し、制御データに含まれるワンタイムパスワード（ＯＴＰ）と記憶しているワンタイムパスワードとが一致しているときには制御データに含まれるコマンドを実行し、一致していないときにはコマンドを実行しない。【選択図】図３
