1. A vehicle comprising:
- a Low Frequency (LF) communication unit transmitting an authentication request signal to a smart key through an LF communication network;
a Radio Frequency (RF) communication unit receiving an authentication response signal from the smart key through an RF communication network; and
a controller measuring an authentication response time period between a time at which the authentication request signal is transmitted and a time at which the authentication response signal is received and determining whether authentication with the smart key is successful based on the authentication response time period.
