Smart Car Key Security Features A smart key communicates with your vehicle all the time whether it's in your pocket or sitting on your desk. They communicate with one another through radiofrequency waves. When the smart key is in range, a computer inside your car recognizes the rolling code projected by the fob of the key and confirms it prior to getting the engine started. This helps to deter thieves. Security Many drivers are skeptical about the transfer of control of their vehicle to a virtual key via a smartphone, with security being one of the most pressing concerns. The good news is that a smart car key can be used with many of the same security features as traditional fobs. For starters, smart keys use fingerprint recognition to unlock and lock doors. To make use of this feature, a driver must put their finger on the sensor in or near the door knob or lock handle (depending on the vehicle's configuration). This is similar to how a phone or tablet equipped with an embedded fingerprint scanner functions. A smart key can help protect cars by not sending the same frequency signal repeatedly. If a fob sent a signal each time it was unlocked or opened a trunk remotely, it allows thieves with a technological advantage to connect cars to hotwires and remove them. Smart keys emit a different signal every time a trunk or door is opened remotely. Smart keys also stop cars from being taken away by thieves at fuel stations and other parking lots. This is because they transmit an extremely low-frequency signal that could be picked up by the smart key in close proximity, however, not by any other person or objects that are not within the vehicle. This signal can be detected only within 10 centimeters of a smart key. Therefore, it is impossible to take your vehicle away by taking a transmission. G28CarKeys eliminate the need to rummage through your pockets for keys or secure your car using a remote control. You can unlock your car or begin it by tapping the app on your smartphone. Contrary to traditional key fobs which transmit a low-power signal smart keys connect to your car via radiofrequency waves. The key fob has an encrypted chip that the antenna in your car recognizes. Once you're within of the car's range it will open the doors and/or begin the engine. Some smart keys can also store settings for the steering wheel, mirrors, and the seat. Then, you can change them by pressing one button. This feature is becoming more popular, and a growing number of manufacturers are incorporating this feature to their vehicles. The market for smart keys in the automotive industry is growing rapidly due to the rising demand for safety and security features. These features minimize wear and tear on a car's ignition system and ensure that the driver is the sole person who can stop or start the engine. Smart keys also alert the driver when the battery is in low and make it more difficult for thieves to steal the vehicle. Some systems will also allow you to open your doors from a distance in the event that the smart key battery dies. It is recommended to keep a backup mechanical key in your wallet or a safe location. Autonomy Some smart key systems operate without a key-fob in the driver's pockets. Instead, they operate by pressing the trunk release button or door handle. These systems also operate when a sensor detects that the driver is nearby. The idea is to eliminate the necessity of pressing the key fob while driving, so that drivers can concentrate on driving safely and secure. The technology is already in use in a few luxury vehicles, and it's growing in popularity with mainstream automakers that are trying to keep up with customer demand. Although this feature is convenient however, it can be a risk when the driver fails to take their key fob from 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 device that can open the doors or even the trunk. It's a tactic called a relay attack and it's been used by thieves with the latest technology to take vehicles from motorists at fueling stations and also in parking areas. However, all smart key systems include an alternate method of opening and starting the car in the event that the battery fails. The driver must usually place the dead key fob inside the slot, or place it close to a special area in the cockpit to activate the emergency starting system. This usually involves an inductive coil that transmits energy from the car to the key. Safety The smart key comes with a built-in security feature that locks your vehicle when you leave. The smart key can stop the vehicle from being operated and unlock the trunk the keys remain inside. This helps you avoid being locked from your car in an area that is not safe or while completing the errands. Unlike conventional keys, a smart key fob can communicate with the vehicle using radiofrequency signals. While it's important to keep in mind that your vehicle isn't spying on you, the fact that the key fob sends these signals makes it possible for criminals to steal them and gain control over the vehicle. Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they open a door or remotely pop out the trunk. This means that a cyber-savvy criminal could be able to infiltrate the system and take your vehicle. Smart car keys emit an encrypted code that changes each time they perform the task. This makes them harder to penetrate and more difficult to be exploited by smart thieves. Certain vehicles allow you to start the car by walking up to it and pressing the button. Instead of traditional models that require you to insert and turn the key to start the engine, these systems are powered by a key fob battery. The key fob transmits an alert to the car's signal to tell it that you are close, and the vehicle can then activate its power doors and start the engine.
