Abstract
Provided are a structure of an automobile electronic key for security and a method for performing the function thereof. It is determined whether at least one of a driver seat door closing signal and a brake pedal signal is on. A key fob of an automobile is requested to send the ID thereof, and the ID is received from the key fob when at least one of the driver seat door closing signal and the brake pedal signal is on. The key fob is authenticated using the received ID. An actuator is driven to move a locking member such that a car key is switched to a rotatable state when the key fob passes authentication. The actuator is driven to move the locking member such that the car key is switched to an unrotatable state when the key fob does not pass authentication.
