What Can a Smart Car Key Fob Do For You?
Known as fobs or keyless entry or smart keys, they were introduced by Mercedes in 1998. Key fobs that are computer controlled can accomplish many things, including locking and unlocking a vehicle smart key as well as starting it.

Safety
A smart key fob continually communicates with a vehicle using radiofrequency signals. It transmits a low-power signal that, when pressed tells the car to unlock doors and begin its engine. The car is programmed to recognize the unique encryption code of a particular key fob. This means that if the keyfob is stolen, the car will not start.
A new vulnerability allows thieves to exploit this communication. Relay attacks are carried out using devices that transmit at the same rate as key fobs. How Stuff Works Electronics says that a thief could place one of these devices inside pockets or in a hidden place to block the remote control of the lock. This is a risk that could become more common as more people switch to smart keys.
A smart key fob is not just a security feature, but it can also simplify your life by automatically taking care of the needs of your vehicle.

Additionally, Smart Car Key Fob smart key systems typically do not send the same frequency signal repeatedly which could make them more vulnerable to relay attacks, according to Open Road Auto Group. As such the vehicle that is stolen cannot be connected to a hotwire if equipped with a smart key since the encrypted signal that the key fob transmits is unique to each vehicle. This technology makes it extremely difficult for thieves to steal a car.

One auto editor at CR was able to walk into her Honda Accord to find the windows shut and the sunroof completely open. She was grateful for her smart key car Key that automatically locked the car.
Some smart keys use computer-encrypted signals to thwart car thieves According to How Stuff Works. This technology stops hotwiring, which is when thieves steal the vehicle’s engine control unit (ECM) which is typically located on the front of the engine block. The ECM is responsible for many important functions like engine power, transmission control and other functions.
Other technologies in smart keys include anti-theft codes and an individual security ID assigned to each key, which can block the ignition if it’s not the right one. The security ID is a digit that is transmitted by the ECM from the key to the ignition, and then verified by a sensor in the car.
