1. A method for detecting a smart key around a vehicle, comprising:
searching, by a control part, a smart key around a vehicle by emitting a registration request message at each preset emission period; when a response message to the registration request message is received from the smart key, checking, by the control part, whether the reception of the response message is maintained during a predetermined time; when the reception of the response message is maintained during the predetermined time, emitting, by the control part, an authentication request message containing encryption information for authenticating the smart key; and when an authentication message to the authentication request message is received from the smart key, authenticating, by the control part, the smart key based on the authentication message, wherein the size of the registration request message is smaller than the size of the authentication request message.
