The car is programmed to recognize the unique encrypted code of a specific key fob. This means that if a key fob is stolen, the car can't start.

But a new form of hack can let thieves exploit this communication. Relay attacks are carried out with devices that transmit at the same frequency as keys.

The ECM manages a range of vital functions, such as engine power and transmission control.

Other features of smart keys include anti-theft encryption and an individual security ID assigned to each key, which could disable the ignition in the event that it's not the correct one.
