Smart Car Key Security Features
Smart keys communicate with your vehicle every day, whether in your pocket or on your desk. They communicate via radiofrequency waves.
If the smart key is within range, a computer inside your vehicle detects the rolling code projected by the key fob and verifies it before starting the engine. This helps deter thieves.
Security
Many drivers are reluctant to give control of their car to a virtual fob on the phone. Security is among the primary concerns. The good news is that a smart key can provide many of the same features as a traditional car fob.
Smart keys, for instance, use fingerprint recognition to unlock and lock doors. In order to use the feature, the user must place a finger on the sensor that is placed near the door handle or lock button (depending on the configuration of the vehicle). This is similar to how a smartphone or tablet with a fingerprint scanner integrated works.
A smart key can make cars safer by not transmitting the exact frequency signal repeatedly. If a smart key sends a signal each time it opened or unlocked a trunk remotely, this allows thieves with a technological advantage to hotwire cars and remove them. Thankfully, this is not a problem because smart keys emit an encrypted signal every time the door is opened or the trunk is opened remotely.
Smart keys can also prevent cars being stolen at gas stations and other parking areas. Smart keys emit a low frequency signal that can only be picked up by nearby smart keys, not by people or other objects that are not within the vehicle. The signal can be recognized within 10 cm of the smart key, meaning it is not possible for anyone to steal your car just by picking up a transmission from a nearby fob.
Convenience
Smart keys eliminate the need to rummage through your pockets to locate a key or to secure your car using the remote control. You can unlock your car and start it by tapping on the app on your phone.
Unlike traditional key fobs, that transmit a low-power signal smart keys communicate with your vehicle via radiofrequency waves. The key fob contains an encrypted chip that the antenna inside your vehicle detects. When you are within distance of your car it will unlock the doors and/or start the engine.
Some smart keys can also save settings for the seats or steering wheel, as well as mirrors, allowing you to set them using just one button. This feature is becoming more popular and a rising number of manufacturers are introducing it to their automobiles.
The automotive smart key market is booming due to increasing demand for safety and security features. These features reduce the wear and tear on the ignition system of a car and guarantee that only the driver has the ability to start or stop the engine. Moreover, smart keys can also notify the driver when the battery is running low making it more difficult for thieves to take the vehicle.
Some systems will also allow you to open your doors at a distance if the battery in your smart key goes out. But, it's better to have a spare mechanical key that is hidden in your wallet or somewhere else safe.
Autonomy
Certain smart key systems work without a key fob in the pockets of the driver. Instead, they function by pressing the trunk release lever or door handle. These systems can also be activated if a sensor detects a driver's proximity.
The idea is to avoid pressing a key fob while driving, allowing drivers to focus on driving safely and secure. The technology is available in some premium cars, and is gaining popularity with mainstream automakers who are trying to meet customer demand.
This feature is useful, but it can also be dangerous if a driver forgets to take the key fob out of their pocket prior to entering or leaving the vehicle. Because smart key fobs emit an ultra-low-frequency signal that could be picked up by a device that can open the doors or pop the trunk. It's a tactic referred to as relay attack, and it's been employed by tech-savvy thieves to steal cars from drivers at fueling stations as well as parking garages.
However, all smart key systems have an alternative method of opening and re-starting the vehicle in the event that the battery goes out. The driver must usually place the dead key in the slot or place it in a specific area of the cockpit to trigger an emergency starting system, which usually involves an inductive coil which transfers energy from the key to the car.
Safety
The smart key comes with an inbuilt security feature that locks the vehicle once you leave. It will even shut down the engine and unlock the trunk if you have locked the keys inside. This will keep you from being locked out of your vehicle in a dangerous location or when you are running an errand.
Smart key fobs communicate with vehicles using radiofrequency signals, in contrast to conventional keys. While it's important to keep in mind that your vehicle isn't spying on your, the fact that the key fob sends these signals allows a criminal to intercept them and gain control over the vehicle.
G28 explains that traditional key fobs emit the same frequency signal each time they open the door or remotely open the trunk. This means that a cyber-savvy criminal could possibly penetrate the system and steal your vehicle. Smart car keys emit an encrypted code that changes each time they perform the task. This makes them difficult to penetrate and more difficult to exploit by tech-savvy thieves.
Certain vehicles let you start the car by walking up to it and pressing the button. These systems, unlike traditional models that require you to insert and turn the keys to start the car, are powered by key fob batteries. The key fob will send an indication to the car's signal to notify it that you're close, and the car can then turn on its power doors and start the engine.
