Safety
A smart key fob communicates with the vehicle through radiofrequency signals. It sends a low-power signal that, when pressed, tells the car to unlock doors and start the engine. The car recognizes the unique encrypted code that is generated by a specific key fob. This means that if the key fob is stolen, the car can't start.
A new hack allows thieves to take advantage of this type of communication. Relay attacks are carried out using devices that transmit at the same rate as a key fob.

Therefore a stolen vehicle can't be connected to a hotwire if equipped with a smart key as the encrypted signal that the key fob transmits is unique to each car. This makes it extremely difficult for thieves to steal cars.

According to How Stuff Works, some smart keys make use of computer-encrypted signals to protect against car thieves. This technology blocks hotwiring, which thieves steal a vehicle's engine controller module (ECM) which is typically located in front of the engine. The ECM manages a range of vital functions, such as engine power and transmission control.
Smart keys also have anti-theft codes, as well as an unique ID security code that is assigned to each key. This could disable the ignition when the wrong key is used.
