Abstract
A smart key system of a vehicle that notifies a user that a fob battery needs to be replaced, including a fob configured to transmit information that the battery needs to be replaced to an in-vehicle communication module configured to transmit the information to an identification authentication unit (IAU); and the IAU configured to transmit the information to an integrated body unit (IBU) configured to notify a user of the information. A smart key system includes: a fob configured to transmit failure information to a BLE module when UWB communication fails due to battery voltage drop; the BLE module configured to receive the failure information, and measure a distance for positioning the fob using a BLE signal; and an IBU configured to transmit an operation signal to a controller configured to control at least one function among vehicle door opening and closing, vehicle start, remote parking, and vehicle door locking.
