Smart Car Key Security Features A smart key communicates with your vehicle at all times regardless of whether it's inside your pocket or on your desk. They communicate via radiofrequency waves. When the smart key is within range, the computer in your car detects and validates the rolling code projected from the key fob before getting the car started. This helps to deter thieves. Security Many drivers aren't keen to hand over control of their car to a virtual fob that is on smartphones. Security is one of the primary concerns. The good news is that a smart key has many of the same features as a traditional car fob. Smart keys can lock and unlock the doors by using fingerprint recognition. To make use of this feature, the user 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 phone or tablet equipped with an embedded fingerprint scanner operates. Another way that smart keys can keep cars safer is by not sending the same frequency signal over and over again. If a fob broadcasted the same signal every time it locked a door, or remotely opened the trunk, it would permit thieves with a tech-savvy mindset to wire vehicles and remove them. Smart keys emit a different signal each time a trunk door is opened remotely. Smart keys can also in preventing theft of cars at gas stations or other parking spaces. Smart keys emit an extremely low-frequency signal that can only be picked up by nearby smart keys, not by any other objects that are not within the vehicle. This signal can only be detected within 10 centimeters of the smart key, which means it is impossible for anyone to steal your car by stealing a transmission from a fob that is nearby. Convenience Smart keys will no longer require you to search your pockets to find a key, or lock the vehicle using remote. Instead, you can tap your phone in the app to unlock the car or start the engine. Then, drive away! Unlike traditional key fobs, which transmit a low-power signal smart keys communicate with your car via radiofrequency waves. The key fob contains an encrypted chip which the antenna inside your vehicle recognizes. Once you're within range of your car it will unlock the doors and/or start the engine. super fast reply save settings for the seat or steering wheel, as well as mirrors and allow you to change them with just one button. This feature is becoming increasingly popular, and a greater amount of manufacturers are adding this feature to their vehicles. The automotive smart key industry is booming because of the increasing demand for security features. These features decrease the wear and tear of the ignition system of a vehicle and ensure that the driver is the sole person who can stop or restart the engine. Smart keys can also alert the driver when the battery is not fully charged, making it harder for thieves to steal the car. Some systems let you open the door from a distance if the battery of your smart key runs out. It is best to keep a backup mechanical key in your wallet, or in a safe place. Autonomy Certain smart key systems function without a key fob that is in the driver's pockets. Instead, they function by pressing the trunk release or car door handle. These systems also work when a sensor detects that the driver is nearby. The idea is to eliminate the need to press the key fob while driving, so that drivers can concentrate on driving safely and secure. The technology is available in some premium cars, and is gaining popularity among automakers of all kinds who are working to meet consumer demands. Although this feature is convenient but it could be risky when the driver fails to take their key fob from the pocket prior to leaving or entering the vehicle. Smart key fobs emit low-frequency signals which can be detected by other devices that open doors or crack the boot. This is a technique known as a relay, and it's been used by cyber-savvy criminals to steal cars from fueling stations as well as parking lots. Most smart key systems do have a backup system to open and start the vehicle in the event of a dead battery. The driver must usually place the dead key fob in a slot, or hold it close to a specific space in the cockpit to start the emergency starter. This usually involves an inductive coil that transmits energy from key to car. Safety The smart key has an inbuilt security feature that locks your vehicle after you leave. It can even shut down the engine and unlock the trunk in case you've put the keys in. This will keep you from being locked out of your car in an unsafe location or when running the errands. Smart key fobs connect to vehicles using radiofrequency signals, in contrast to conventional keys. It's important to remember that your car is not spying on you. However, because the key fob transmits these signals, it's possible for a criminal intercept them and control the vehicle. Open Road Auto Group explains traditional key fobs emit the same frequency signal every time they unlock doors or remotely pop out the trunk. This means that a cyber-savvy criminal could be able to penetrate the system to steal your vehicle. Smart car keys generate a different encrypted code each time they carry out some function. This makes them harder to hack and harder to be exploited by smart thieves. Certain vehicles also allow you to start your car by walking to it and pressing the button. In contrast to traditional models that require you to insert and turn the key to start the engine, these systems are powered by a key fob's battery. The key fob transmits an signal to the car's antenna to tell it that you are close, and the car will then be able to open its power doors and begin the engine.
