Smart keys, for instance, utilize fingerprint recognition to lock and unlock doors. To use this feature, a person must place their finger on the sensor close to the lock button or door handle (depending on the configuration of the vehicle). This is similar to how a tablet or smartphone with an embedded fingerprint scanner operates.

Another way that smart keys help keep cars safe is by not sending the same frequency signal over and over again. If a fob sent the same signal every time it opened the door remotely or opened the trunk, it could permit thieves with a tech-savvy mindset to use hotwires to make them disappear. Fortunately, this isn't a problem because smart keys emit a unique encrypted signal each time an opening is made on a door or the trunk is opened remotely.

Smart keys also help prevent cars from being stolen by thieves at fueling stations and other parking spaces. Smart keys transmit an extremely low-frequency signal that can only be detected by nearby smart keys, and not by people or other objects outside the vehicle. This signal can be detected at a distance of 10 cm from the smart key. So, it's impossible to steal your vehicle simply by taking an engine.

Convenience

Using smart keys eliminates the need to dig through your pockets in search of keys or to lock the car with remote controls. You can open your car door or start it by tapping the app on your phone.

Smart keys, unlike traditional keys that transmit the signal with low power they communicate with your car through radiofrequency waves. The key fob is equipped with an encrypted chip that the antenna inside your vehicle recognizes. When you get within range of your car it will open the doors and/or start the engine.

Some smart keys can also save settings for the steering wheel, mirrors and the seat. Then, you can change them by pressing one button. This feature is becoming more popular and a growing number of manufacturers are incorporating it to their vehicles.

The automotive smart key market is growing because of the increasing demand for security and safety features. These features help reduce wear on the ignition system of a car and guarantee that only the driver is able to start or stop the engine.

The idea is to eliminate the necessity of pressing the key fob while driving, allowing drivers to concentrate on driving safely and securely. The technology is present in a few premium cars and is growing in popularity among automakers of all kinds who are working to meet consumer needs.

Although this feature is convenient but it could be risky If the driver isn't careful to take their key fob out of the pocket prior to getting into or out of the vehicle. Smart key fobs emit low-frequency signals that can be picked up by other devices that open doors or even pop the boot. This is a tactic known as relay attack, and it has been used by thieves who are tech-savvy to steal vehicles from motorists at fuel stations, as well as in parking lots.

Most smart key systems do include a backup mechanism for opening and starting the vehicle in the case of a dead battery. The driver should usually insert the dead key fob inside a slot or hold it near to a designated area in the cockpit, to start the emergency starter.

While it's vital to keep in mind that your vehicle isn't spying on you however, the fact that the key fob transmits these signals makes it possible for a criminal 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 means that a tech-savvy criminal could hack into the system to take your vehicle. Smart car keys emit an encrypted code that changes every time they complete some function. This makes them more difficult to break and more difficult to exploit by hackers.

Certain vehicles let you start the car by walking right up to it, pressing a button. These systems, unlike traditional models that require you insert and turn the keys they are powered by key fob batteries. The key fob sends an signal to the car's radio to tell it that you are close to the vehicle, and it can then turn on its power doors and start the engine.
