Safety
A smart key fob continually communicates with vehicles through radiofrequency signals. It transmits a low-power signal that, when pressed will instruct the car to open doors and begin its engine. The car can recognize the unique encrypted code from a specific key fob. This means that in the event that the keyfob is stolen, the car is unable to start.
A new vulnerability allows thieves to exploit this communication. Relay attacks are carried out with devices that transmit at the same frequency as keys. How Stuff Works Electronics says that a thief could place one of these gadgets into the pocket or hidden area to block the key fob's lock command remotely. This is a problem that could become more frequent as more people are switching to smart keys.

Certain smart keys, like the Display Key, come with small LCD touchscreen that allows users to access features like locking, unlocking, and keyless starting directly from their key fob, without the need to connect to the Bluetooth system in the car.
A smart key can help drivers save time by automating the closing of their car doors after they leave. This feature is present in a wide range of vehicles, according to Consumer Reports, and can also make it easier to move into parking spots that are tight without accidentally squeezing something or someone else.
Open Road Auto Group explains that smart key systems don't transmit the same frequency signal in a series of which can make them more susceptible 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 car. This makes it very difficult for thieves steal the car.
Security
Today's newer cars pack in more high-tech electronic features than ever before, and a few of them are housed on the key fob. These devices do much more than lock and unlock doors or emit chirping sounds to help drivers find their vehicle in a parking lot However, some owners may not be aware of all that these smart key fobs can accomplish.
For example, some smart keys are able to activate the auto windows of a car and sunroof when press. A auto editor for CR once went out to her Honda Accord only to find all the windows closed and the sunroof opened. She was thankful for her Smart Key that automatically locked the car.
According to How Stuff Works, some smart keys use computer encrypted signals to stop car thieves. This technology blocks hotwiring, which thieves steal a vehicle's engine controller module (ECM) typically located in front of the engine. The ECM manages a range of vital functions, including engine power and transmission control.
Other technologies used in smart keys include anti-theft encryption 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, followed by verification by a sensor located in the car.
