Known as fobs, keyless entry or smart keys, they were introduced by Mercedes in 1998. Key fobs that are controlled by computers accomplish many things, including locking and unlocking vehicles as well as starting it.

Safety
A smart key fob that communicates continuously with a vehicle via radiofrequency waves. It sends out a low-power signal that, when pressed signals the car to unlock doors and start the engine. The car is programmed to recognize the unique encryption code of a specific key fob. This means that in the event that the keyfob is stolen, the car can't be started.
However, a new kind of hacking could enable thieves to gain access to that communication. Relay attacks are carried out using devices that transmit at the same frequency as the key fob. How Stuff Works Electronics says that thieves could put one of these devices inside a pocket or hidden spot to block the remote control of the lock. This is a problem that may become more common as more people are switching to smart keys.

Many smart key fobs come with an indicator for the battery that alerts you in advance that the battery is running low. And replacing the battery in most models is a quick and simple procedure that doesn't require any special tools.
Convenience
Smart keys do not need to be physically inserted into an ignition slot to unlock or start the vehicle. BMW Group explains that the driver just needs to bring the key within the range of the car. Certain smart keys, such as the Display Key, come with small LCD touchscreen that grants drivers access to features like locking, unlocking, and keyless start directly from their key fob, without the need to connect to the Bluetooth system of the car.
Another way smart keys can save drivers time is by automatizing the process of locking their car doors after they leave. Consumer Reports says that this feature is present on a variety of vehicles. It can also make it easier for drivers to maneuver into tight spaces without accidentally hitting the door or something else.
Smart key systems do not typically send the same frequency signal over and over and this can make them more susceptible to relay attacks, explains Open Road Auto Group. So the vehicle that is stolen cannot 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 technology makes it extremely difficult for thieves to steal cars.
Security
Modern cars have more advanced electronic features than ever before, and some of them are contained inside the key fob. These devices are capable of more than just locking and unlocking doors, or making chirping noises to help motorists locate their car in parking spaces. However certain owners might be unaware of the full capabilities.
For example, some smart keys can trigger the auto windows of a car and sunroof when they are hit. A CR auto editor once walked out to her Honda Accord only to find all the windows closed and sunroof up. This is one of the reasons she was grateful for her Smart Key, which locked the car automatically.
Certain smart keys use encrypted computer signals to thwart car burglars According to How Stuff Works. This technology can prevent hotwiring in which thieves steal a vehicle's engine controller module (ECM) which is usually located in front of the engine. The ECM controls a variety of essential functions, including engine power and transmission control.
Other smart keys' features include anti-theft code and a unique security ID that is assigned to each key, which can block the ignition if it's not the correct one. The security ID is a digit that is transmitted by the ECM from the key to the ignition, and then validated by a sensor inside the car.

In some instances the smart key may cease to function completely. If you suspect this is the case Try to reset the smart key by exiting the vehicle and then returning to it. This will enable the car to understand that the key fob remains in the vehicle and let it to regain its functionality.
