Abstract: A vehicle communicating with a remote controller is provided. A vehicle includes a plurality of car antennas; a storage configured to store a distance value between the first and second key antennas; and a controller configured to select at least two of the plurality of car antennas, control transmission of signals through the selected at least two car antennas, obtain a distance value between the first and second key antennas of the remote controller based on the received signal strength and the transmission strength of the at least two car antennas when a received signal strength of at least two signals received by the first key antenna and a received signal strength value of at least two signals received by the second key antenna are received from the remote controller, and authenticate the remote controller based on the obtained distance value and the distance value stored in the storage.

Abstract: A vehicle may include: a conductive coil; and an authenticator configured to be turned on in response to receiving a current and to request an encryption key from a remote control apparatus. An induction current may be induced in the coil when a magnetic body approaches the coil, and the authenticator may be further configured to be activated in response to receiving the induction current from the coil.
