For starters, smart keys utilize fingerprint recognition to lock and unlock doors. To use the feature, a driver must place their finger on the sensor 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.

Smart keys can also ensure the safety of vehicles by not sending the exact frequency signal repeatedly. If a key sent the same signal every time it unlocked a door or remotely opened the trunk, this would permit thieves with a tech-savvy mindset to wire vehicles and make them disappear. Fortunately, this isn't a problem because smart keys emit an encrypted signal every time an opening is made on a door or the trunk is remotely opened.

Smart keys also protect cars from being stolen by thieves at fuel stations as well as other parking spots. Smart keys send the signal at a low frequency that can only be picked up by nearby smart keys, not by objects or individuals that are not within the vehicle. The signal can be detected only within 10 centimeters of the smart key. Thus, it is impossible to steal your vehicle just by taking an engine.

While this feature is convenient however, it can also be dangerous If the driver isn't careful to take their key fob out of the pocket before entering or exiting the vehicle. That's because smart key fobs emit an ultra-low-frequency signal that could be picked up by another device that could unlock the doors or open the trunk. It's a tactic referred to as relay attack, and it's been used by thieves who are tech-savvy to take vehicles from motorists at fuel stations, and even in parking garages.

The majority of smart key systems come with a backup system to start and open the vehicle in the case of an insufficient battery.

Open Road Auto Group explains traditional key fobs emit the same frequency signal every time they unlock a door or remotely pop out the trunk. This means that a cyber-savvy criminal could possibly hack into the system and steal your vehicle. Smart car keys, however, send out an encrypted signal each time they are used. This makes them harder to crack, and even more difficult for thieves who are tech-savvy to gain access to.

Certain vehicles allow you to start your car by simply walking towards it and pressing the button. In contrast to traditional models that require you to insert and turn the key, these systems are powered by a key fob's battery.
