What Can a Smart Car Key Fob Do For You?
Mercedes introduced the first fobs in 1998. They are also known as smart keys, keyless entry or keyless entry fobs. They are computer-controlled and capable of performing many tasks, such as locking and unlocking your car or the car's start-up.
They transmit an encrypted, rolling signal. This makes them more receptive to tech-savvy thieves.
Safety
A smart key fob communicates with vehicles via radiofrequency waves. smart car key coding sends a low-power signal that, when pressed it, signals the vehicle to unlock doors and start the engine. The car can recognize the unique encrypted code from a particular keyfob. This means that even when the key fob is stolen, it can't be used to begin the car.
But a new form of hacking can enable thieves to gain access to that communication. Relay attacks use devices that transmit at the same frequency as the key fob. A thief can place one of these devices in a purse or hiding area to disable the lock command from a distance, says How Stuff Works Electronics. This issue could become more common as more motorists switch to smart keys.

Some smart keys, like the Display Key, have an incredibly small LCD touchscreen that grants users access to features such as locking, unlocking, and keyless start directly from their key fob, without needing to connect to the Bluetooth system in the car.
Another way that smart keys could help save time for drivers is by automating the process of locking their doors when they leave it. This feature is available in many automobiles, according to Consumer Reports, and can assist in allowing drivers to navigate through parking spaces that are tight without accidentally squeezing something someone else.
Open Road Auto Group explains that smart key systems don't transmit the same frequency signal repeatedly and this could make them more vulnerable to relay attacks. So it is impossible for a stolen car to be connected to a hotwire if equipped with a smart-key because the encrypted signal that the key fob transmits is unique to each vehicle. This makes it extremely difficult for thieves to steal a car.
Security
Modern cars come with more advanced electronic features than ever before, and some of them are found on the key fob.

According to How Stuff Works, some smart keys utilize computer-encrypted signals to deter car thieves. This technology is able to prevent hotwiring where thieves steal the vehicle's engine control module (ECM), which is typically located in the front of the engine block. The ECM is responsible for a variety important functions, including transmission control and engine power.
Other smart keys' features include anti-theft coding 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 verified by a sensor in the car.
