The car recognizes the encrypted code that is generated by a specific key fob. This means that even in the event that the key fob gets stolen, it can't be used to begin the car.
A new vulnerability allows thieves to take advantage of this type of communication. Relay attacks use devices that transmit at the same frequency as the key fob.

A smart key can also save drivers time by automating the closing of their car doors after they leave. Consumer Reports says that this feature is offered on a number of vehicles. It also makes it easier for drivers to maneuver around tight spots without accidentally squeezing someone or something.
Open Road Auto Group explains that smart key systems do not transmit the same frequency signal in a series of and this could make them more vulnerable to relay attacks. Smart keys are specific to each vehicle so a stolen car cannot be wired. This technology makes it extremely difficult for thieves to steal a car.
Security
Some of the latest electronic features in today's newer automobiles can be found in the key fob.

This technology prevents hotwiring in which thieves steal a vehicle's engine controller module (ECM), usually located in front of the engine. The ECM manages many essential functions, including engine power, transmission control and many more.
Smart keys also come with anti-theft codes and a unique security ID code assigned to each key. This could stop ignition when 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 verified by a sensor located in the car.
