Smart Car Key Security FeaturesSmart keys communicate with your vehicle all the time regardless of whether it's in your pocket or sitting on your desk. They communicate with radiofrequency waves.If the smart key is within range, a computer within your vehicle is able to recognize the rolling code projected by the fob of the key and verifies it before getting the engine started. This helps thwart thieves.SecurityMany drivers are wary of giving control of their vehicle to a virtual key that is stored on a smartphone, with security being among the primary concerns. The good news is a smart key can provide many of the same features as a traditional car fob.For starters, smart keys use fingerprint recognition to unlock and lock doors. To make use of this feature, the user must place their finger on a sensor close to or in the vicinity of the lock button or door handle (depending on vehicle configuration). This is similar to the way a tablet or smartphone with a fingerprint scanner integrated functions.Another way that smart keys can keep cars safe is by not sending the same frequency signal over and over again. If a fob broadcasted a signal each time it opened or locked an trunk remotely, this could allow thieves to wire cars to drive them away. Smart keys emit a unique signal every time a trunk or door is opened remotely.Smart keys also help protect cars from theft at gas stations or other parking spots. This is because they transmit the signal at a low frequency that can be picked up by an adjacent smart key however, not by any other person or objects outside of the vehicle. This signal can be detected at a distance of 10 cm from the smart key. This means it is impossible to steal your vehicle simply by taking the transmission.ConvenienceSmart keys eliminate the need to rummage through your pockets for a key or even lock the car with remote. Instead, you can tap your phone's app to unlock the car or start the engine. Then, drive away!As opposed to traditional key fobs which transmit a low-power signal, smart keys communicate with your vehicle through radiofrequency waves. The key fob is equipped with an encrypted chip that the antenna in your car recognizes. If you're within distance of your vehicle, it will open the doors or begin the engine.Some smart keys can also store settings for the steering wheel, mirrors and seat. Then, you can change them by pressing a single button. This feature is becoming increasingly popular and a rising number of companies are adding it to their automobiles.The automotive smart key industry is growing rapidly due to the rising demand for safety features. These features lessen wear on the ignition system of a car and guarantee that only the driver has the ability to start or stop the engine. Smart keys can also inform the driver if the battery is low and makes it more difficult for thieves to steal the car.Certain systems allow you to unlock the door remotely in the event that your smart key battery goes out. It is best to keep a mechanical backup key in your wallet or a safe place.AutonomyCertain smart key systems function without a key-fob in the pockets of the driver. Instead, G28 work by pressing the trunk release or car door handle. These systems also operate when a sensor detects that the driver is near.The idea is to eliminate the necessity of pressing a key fob button while driving, allowing drivers to concentrate on driving safely and secure. The technology is available in some premium vehicles, and is gaining traction among major automakers trying to keep up with consumer demand.While this feature can be useful however, it can also be dangerous if the driver forgets to take their key fob from the pocket before getting into or out of the vehicle. That's because smart key fobs emit a low-frequency signal that can be detected by a different device that can open the doors or even the trunk. This is known as relay and has used by hackers to steal cars at fuel stations and parking spaces.However, most smart key systems include an alternative method of opening and re-starting the vehicle if the battery dies. The driver is required to place the dead key fob inside a slot or hold it near a designated area in the cockpit to start the emergency starter. This typically involves an inductive coil that transfers energy from the key to the car.SafetyThe smart key comes with an inbuilt security feature that locks your vehicle whenever you leave. The smart key will shut down the car and open the trunk the keys remain inside. This prevents you from being locked out of your car an unsafe location or when you are running errands.Smart key fobs connect to vehicles using radiofrequency signals, unlike traditional keys. It's crucial to remember that your car isn't tracking you. However, because the key fob transmits these signals, it is possible for a criminal intercept them and control the vehicle.Open Road Auto Group explains that traditional key fobs emit the same frequency signal every time they open the door, or remotely open the trunk. This means that a cyber-savvy criminal could penetrate the system to take your vehicle. Smart car keys, however, put out an encrypted signal each time they use this function. This makes them more difficult to break and more difficult to be exploited by smart thieves.Some vehicles also allow you to start your car by simply walking towards it and pressing a button. In contrast to traditional models that require you to insert and turn the key, these systems are powered by a key fob battery. The key fob transmits an alert to your car's antenna, letting it know that you're close. The car will open the power doors and start its engine.
