Safety

A smart key fob is constantly communicating with a vehicle through radiofrequency waves. It transmits a low power signal that, upon pressing it, prompts the vehicle unlock doors and begin the engine. The car is programmed to recognize the unique encryption code of a particular key fob. This means that even if the key fob is stolen, it won't be used to begin the car.

But a new form of hacking technique can enable thieves to gain access to that communication. Relay attacks are carried out with devices that transmit at the same frequency as key fobs. A burglar can put one of these devices in a pocket or hidden location to thwart the lock command from a distance, says How Stuff Works Electronics.

Open Road Auto Group explains that smart fortwo key programming key systems do not transmit the same frequency signal in a series of which can make them more vulnerable to relay attacks. Smart keys are specific to each vehicle therefore a stolen vehicle cannot be connected to a hotwire. This technology makes it extremely difficult for thieves to steal a vehicle.

Security

For instance, certain smart keys are able to activate windows that automatically open and sunroof when pressed. A auto editor from CR once walked out to her Honda Accord only to find all the windows closed and sunroof opened. She was grateful for her Smart Key that automatically locked the car.

Certain smart keys use encrypted computer signals to stop car thieves, according to How Stuff Works. This technology blocks hotwiring in which thieves steal the engine control module (ECM) which is usually located in the front of the engine block. The ECM manages many essential functions like engine power, transmission control and many more.

Other features of smart key market keys include anti-theft encryption and a security ID unique to each key. This could disable the ignition in the event that it's not the correct one. The security ID is a number that is transmitted by the ECM from the key to the ignition, and then confirmed with a sensor in the car.
