Smart Car Key Security Features A smart key communicates with your vehicle at all times 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 inside your vehicle is able to recognize the rolling code projected by the fob of the key and validates it prior beginning the engine. This helps to deter thieves. Security Many drivers are hesitant about giving control of their vehicle to a digital key via a smartphone, with security being among the most important concerns. The good news is that a smart key comes with many of the same features that a traditional car fob does. Smart keys can lock and unlock the doors through fingerprint recognition. To make use of this feature, the driver has to put their finger on the sensor near or inside the door knob or lock handle (depending on the configuration of the vehicle). This is similar to how a tablet or smartphone with the fingerprint scanner inside operates. Another way that smart keys help keep vehicles safe is by not sending the same frequency signal repeatedly again. If a key sent the same signal each time it unlocked a door, or remotely opened the trunk, this could allow thieves who are tech-savvy to hotwire vehicles and make them disappear. Thankfully, this is not an issue because smart keys emit an encrypted signal each when the door is opened or the trunk is opened remotely. Smart keys also prevent the theft of cars by thieves at fueling stations and other parking lots. Smart keys send a low frequency signal that can only be detected by nearby smart keys, and not by any other objects outside the vehicle. This signal can be detected just within 10 cm of a smart key. Therefore, it is impossible to steal your vehicle just by picking up a transmission. Convenience Using smart keys eliminates the need to fumble through your pockets to locate keys or to lock the car with remote controls. You can unlock your car or start it by tapping the app on your smartphone. As opposed to traditional key fobs which transmit a low-power signal smart keys communicate with your vehicle via radiofrequency waves. The key fob has an encrypted chip that the antenna inside your vehicle detects. If you reach the of the car's range it is able to open the doors and/or begin the engine. Some smart keys can also store settings for the seats, mirrors and steering wheel, allowing you to set them using just one button. This feature is becoming more popular and a rising number of manufacturers are incorporating it to their vehicles. The market for automotive smart keys is growing rapidly due to the growing demand for safety features. These features help reduce the wear and tear on the ignition system of a car and ensure that only the driver has the ability to start or stop the engine. Moreover, smart keys can also notify the driver that the battery is not fully charged and make it less difficult for thieves to steal the vehicle. Certain systems will also allow you to unlock your door from a distance when the battery of your smart key dies. It is recommended to keep a backup key in your wallet or another safe location. Autonomy Some smart key systems operate without a key fob in the pockets of drivers. Instead, they work by pressing the trunk release lever or door handle. These systems can be activated when a sensor detects the driver's proximity. The goal is to stop pressing a key fob when driving, so that drivers can focus on driving safely and securely. The technology is available in a few premium cars and is getting more popular with automakers that are working to meet consumer demand. While this feature is convenient however, it can be a risk if the driver forgets to take their key fob out of the pocket prior to getting into or out of the vehicle. The reason is that smart key fobs emit an low-frequency signal which can be detected by a different device that can open the doors or pop the trunk. This is known as relay and has utilized by criminals with a tech-savvy to steal cars from fuel stations and parking spaces. However, most smart key systems include an alternate method of opening and re-starting the vehicle in the event that the battery goes out. The driver usually must put the dead key fob into the slot or place it in a specific area of the cockpit to trigger an emergency start system, which is usually an inductive coil that transfer energy from the key to the car. Safety The smart key comes with an inbuilt security feature that locks your vehicle whenever you leave. It will even shut down the engine and unlock the trunk in case you've left the keys inside. This will prevent you from being locked out of your vehicle in an area that is not safe or when you are running on errands. Smart key fobs communicate with vehicles using radiofrequency signals, which is different from conventional keys. It's important to keep in mind that your car isn't monitoring you. However, since 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 each time they open the door or remotely pop the trunk. This means a tech-savvy criminal could be able to penetrate the system and steal your vehicle. G28 Car Keys emit an encrypted message every time they perform some function. This makes them harder to penetrate and more difficult to exploit by hackers. Some vehicles allow you to start the car by walking towards it, and pressing a button. Instead of traditional models that require you to insert and turn the key in order to start, 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 activate the power doors and begin its engine.
