The present invention relates to a system for alarming upon occurrence of secession of a smart key for a vehicle, in which wireless communication technology called near field communication (NFC) is applied to both a vehicle and a smart key such that a situation can be prevented in which a driver loses a smart key or does not carry it during the driving. The inventive system includes a signal generation unit, a signal response unit, a signal analysis unit, and an alarm generation unit. Thus, when the smart key secedes from the vehicle by a predetermined distance or the signal generation unit does not receive the response signal from the signal response unit in a state in which the engine of the vehicle is started, an alarm signal is produced from the alarm generation unit. |
