A smart key system for a vehicle includes a communication unit configured to communicate with a smart key, memory configured to store a code and a count that are included in a signal received from the smart key, and a processor configured to identify whether the smart key has been registered with the vehicle based on the signal, determine whether the count is normal by comparing the count with a pre-stored count, control a door of the vehicle in response to the code when the count is normal, and control the door to maintain a lock state when the count is not normal. The present disclosure has effects in that a signal of the smart key and a hacked signal can be easily distinguished and the security of a vehicle can be improved by using a count that is generated based on the vibration of the smart key.
