If the smart key is in range, a computer in your vehicle detects the rolling code projected by the key fob and verifies it before beginning the engine. This helps to deter thieves.
Security
Many drivers aren't comfortable the transfer of control of their vehicle to a virtual key that is stored on a smartphone, with security being one of the most pressing concerns. The good news is a smart key comes with many of the same features that a traditional car fob does.
Smart keys lock and unlock the doors by using fingerprint recognition. To use this feature, a person must put their finger on a sensor located close to the door knob or lock handle (depending on the configuration of the vehicle). This is similar to how a smartphone or tablet with an embedded fingerprint scanner functions.
A smart key can also make cars safer by not sending the exact frequency signal repeatedly. If a smart key sends an individual signal each time it opened or locked a trunk remotely, it will allow tech-savvy thieves to wire cars to eliminate them. Smart keys emit a unique signal every time a trunk or door is opened remotely.
Smart keys also prevent cars from being taken away by thieves at fuel stations as well as other parking spots. Smart keys transmit the signal at a low frequency that can only be detected by nearby smart keys, and not by other objects or people that are not within the vehicle. The signal is detectable only within 10 centimeters of a smart key. Thus, it is impossible to steal your vehicle just by picking up an engine.
Convenience
Smart keys eliminate the need to search your pockets for keys or even lock the car with remote. Instead, simply tap your phone in the app to unlock or start the engine and go on your way!
In contrast to traditional key fobs which transmit a low-power signal, smart keys connect to your vehicle through radiofrequency waves. The key fob contains an encrypted chip that the antenna in your vehicle detects. When you are within reach of your vehicle it will unlock the doors or begin the engine.
Some smart keys can also store settings for the steering wheel, mirrors, and seats. Then, you can change them by pressing one button. This feature is becoming more popular and a growing number of manufacturers are introducing it to their vehicles.

These features help reduce the wear and tear of the ignition system in a car and ensure that the driver is the only person who can stop or restart the engine.

The idea is to remove the necessity of pressing a key fob button while driving, so that drivers can concentrate on driving safely and securely. The technology is currently available in certain luxury vehicles, and is becoming popular with automakers that are trying to meet customer demands.
This feature is helpful however, it could be dangerous if a driver does not take the key fob out of their pocket prior to leaving or entering the vehicle. Smart key fobs emit low-frequency signaling that can be picked up by other devices that open doors or pop the boot. This is a technique called relay and has used by hackers to steal cars from fueling stations as well as parking lots.
Most smart key systems do come with a backup method for opening and starting the vehicle in the case of an insufficient battery. The driver should usually insert the dead key in a slot, or hold it close to a specific area in the cabin to activate the emergency start system. This typically involves an inductive coil which transfers energy from the key to the vehicle.

In contrast to conventional keys, a smart key fob communicates with the vehicle via radiofrequency signals. While it's important to keep in mind that your vehicle isn't spying on you, the fact that the key fob sends these signals makes it possible for criminals to intercept them and gain control over the vehicle.
Open Road Auto Group explains that traditional key fobs send out the same frequency signal each time they unlock the door or remotely open the trunk. This implies that a hacker could infiltrate the system and steal your vehicle. Smart car keys, however, put out an encrypted signal each time they do this. This makes them harder to crack, and even more difficult for thieves who know how to make use of.
Certain cars allow you to start the vehicle by walking up to it and pressing a button. These systems, unlike traditional models that require you to insert and turn the keys and are powered by key fob batteries. The key fob sends an indication to your car's antenna, letting it know that you're within. The car will open the power doors and begin its engine.
