Smart Car Key Security Features A smart key is in communication with your vehicle at all times, whether it's in your pocket or sitting on your desk. They communicate by using radiofrequency signals. If the smart key is in reach, the computer inside your car recognizes and verifies the rolling code projected from the key fob prior to beginning the car. This helps thwart thieves. Security Many drivers are skeptical about handing over control of their vehicle to a virtual key that is stored on a smartphone, with security being among the main concerns. The good news is that the smart car key comes with the same security features as the traditional fob. Smart keys can lock and unlock the doors by using fingerprint recognition. To access the feature, the driver needs to apply a finger to the sensor that is placed near the door handle or lock button (depending on the car's configuration). This is similar to how a phone or tablet equipped with an embedded fingerprint scanner works. A smart key could also help to protect vehicles by not sending the exact frequency signal repeatedly. If a smart key sends an alert each time it was unlocked or opened a trunk remotely, this could allow thieves to hotwire cars and remove them. Fortunately, this isn't a problem because smart keys emit a different encrypted signal each time the door is opened or the trunk is remotely opened. Smart keys also help prevent vehicles from being taken by thieves at fuel stations as well as other parking spots. This is because they transmit the signal at a low frequency that can be picked up by a nearby smart key, but not by other people or objects that are not within the vehicle. The signal is detectable at a distance of 10 cm from the smart key. So, it's impossible to steal your vehicle by simply taking a transmission. Convenience Smart keys eliminate the need to search through your pockets for a key, or lock the vehicle using remote. Instead, just tap on your phone's app to unlock the car or start the engine, and then drive away! Smart keys, in contrast to traditional key fobs that transmit low-power signals that communicates with your car via radiofrequency waves. The key fob contains an encrypted chip which the antenna in your vehicle recognizes. If you reach the of the car's range it will unlock the doors and/or start the engine. Some smart keys can also save settings for the seat mirrors, the steering wheel and seat and allow you to change them with a single click. This feature is becoming more popular and a growing number of manufacturers are incorporating it to their automobiles. The market for automotive smart keys is booming due to the increasing demand for safety features. These features reduce the wear and tear on a car's ignition system and ensure that the driver is the only person who has the ability to stop or start the engine. Smart keys also notify the driver that the battery is not fully charged making it harder for thieves to steal the vehicle. Certain systems allow you to unlock the door remotely in the event that your smart key battery goes out. But, it's better to have a spare mechanical key that you can keep in your wallet or else secure. Autonomy Rather than an actual key fob that needs to be in the driver's pocket to unlock or start a car, some smart key systems operate when the car door handle or trunk release button is pressed. These systems also operate when a sensor senses the driver is nearby. The idea is to avoid the need to use a key fob while driving, allowing drivers to concentrate on driving safely and in a secure manner. The technology is already available in some premium cars, and is growing in popularity among automakers of all kinds who are trying to meet customer demands. This feature is useful however, it could be risky if someone fails to remove the key fob from their pocket before entering or leaving the vehicle. Because smart key fobs emit a low-frequency signal that can be picked up by a device that can open the doors, or even pop the trunk. It's a tactic called a relay attack, and it's been used by tech-savvy thieves to take vehicles from motorists at fueling stations, and even in parking lots. The majority of smart key systems have a backup system for opening and starting the vehicle in the event of the battery being dead. The driver must usually place the dead key fob in a slot or hold it in a designated space in the cockpit, to trigger an emergency starting system, which is usually an inductive coil that transfers energy from the key to the vehicle. Safety The smart key comes with a built-in security feature that locks your vehicle when you leave. The smart key will shut down the vehicle and open the trunk if the keys are still inside. This prevents you from being locked out of your car an unsafe area or while you run the errands. Smart key fobs connect to vehicles using radiofrequency signals, unlike conventional keys. While it's important to remember that your vehicle isn't spying on you, the fact that the key fob sends these signals allows a criminal to intercept them and gain control of the vehicle. Open Road Auto Group explains that traditional key fobs transmit the same frequency signal every time they open the door, or remotely open the trunk. This means that a cyber-savvy criminal could hack into the system and take your vehicle. Smart car keys, however, send out an encrypted signal that is different each time they are used. This makes them more difficult hack and harder to exploit by hackers. Some vehicles allow you to start the car by walking right up to it, and pressing the button. These systems, unlike traditional models that require you insert and turn the keys to start the car, are powered by key fob batteries. The key fob sends an signal to the car's antenna signal it that you're close, and the car will then open its power doors and begin the engine.
