A smart key fob continuously communicates with the vehicle via radiofrequency waves. It sends out a low-power signal that, when pressed it, signals the vehicle to unlock doors and begin the engine. The car is programmed to recognize the unique encryption code of a specific key fob. This means that even when the key fob has been stolen, it cannot be used to begin the car.

The ECM controls a variety of vital functions, including transmission control and engine power.
Smart keys also have anti-theft code and a unique ID security code that is assigned to each key. This could stop ignition if the wrong key is used. The security ID is a unique code that is transmitted by the ECM from the key to the ignition and then validated by a sensor in the car.
