Smart Car Key Security Features A smart key is in communication with your vehicle all the time, whether it's in your pocket or sitting on your desk. They communicate by using radiofrequency signals. When the smart key is in the range of the computer inside your vehicle recognizes the rolling code projected by the fob of the key and validates it prior to beginning the engine. This helps deter thieves. Security Many drivers are hesitant about handing control of their vehicle to a virtual key that is stored on a smartphone, with security being one of 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, utilize fingerprint recognition to lock and unlock doors. In order to use the feature, the driver needs to apply a finger to the sensor that is placed near the door handle or the lock button (depending on the vehicle configuration). This is similar to how a smartphone or tablet with an embedded fingerprint scanner function. Another way that smart keys keep cars safer is by not sending the same frequency signal over and over again. If a fob sent a signal every time it opened or unlocked a trunk remotely, this will allow tech-savvy thieves to use hotwires to connect cars and remove them. Smart keys emit a unique signal each time a trunk door is opened remotely. smart car key case protect vehicles from being taken by thieves at fueling stations as well as other parking spots. This is because they send a low-frequency signal that can be picked up by the smart key in close proximity, 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. So, it's impossible to steal your vehicle just by taking the transmission. Convenience Smart keys will no longer require you to search your pockets for keys or even lock the vehicle using a remote. Instead, tap your phone in the app to unlock the car or start the engine, and then drive away! Contrary to traditional key fobs that transmit a low-power signal smart keys communicate with your vehicle through radiofrequency waves. The key fob has an encrypted chip that the antenna inside your vehicle recognizes. When you get within range of your car, it knows to unlock the doors and/or start the engine. Some smart keys also save settings for the seat and mirrors as well as the steering wheel, allowing you to set them by pressing a single button. This feature is becoming increasingly well-known, and a rising number of automakers are adding this to their vehicles. The automotive smart key industry is growing rapidly due to the growing demand for safety features. These features help reduce the wear and tear of the ignition system in a car and ensure that the driver is the only person who can stop or restart the engine. Smart keys can also alert the driver when the battery is not fully charged and makes it more difficult for thieves to steal the car. Some systems let you open the door from a distance if your smart key battery runs out. It is best to keep a backup mechanical key in your wallet or a secure location. Autonomy Rather than an actual key fob that needs to be kept in the pocket of the driver to unlock or start a car, smart key systems function when the door handle or the button for trunk release is pressed. These systems can be activated when a sensor detects that a driver is near. The idea is to eliminate the necessity of pressing a key fob button while driving, so drivers can concentrate on driving safely and securely. The technology is currently available in a few premium cars and is getting more popular with automakers that are working to meet consumer demands. This feature is helpful however, it could be risky if someone fails to take the key fob out of their pocket before leaving or entering the vehicle. Smart key fobs emit low-frequency signaling that can be picked up by other devices that open doors or even pop the boot. It's a tactic referred to as a relay attack and has been used by tech-savvy thieves to take vehicles from motorists at fueling stations as well as parking areas. Most smart key systems do come with a backup system to start and open the vehicle in the case of the battery being dead. The driver typically has to place the dead key fob in the slot or place it near a special space in the cockpit, to trigger an emergency starting system, which typically consists of an inductive coil that transmits energy from the key to the car. Safety The smart key comes with integrated security features that locks the vehicle once you leave. It will even shut down the engine and unlock the trunk if it is discovered that you have put the keys in. This will prevent you from being locked from your car in an area where it is unsafe or while you run on errands. Unlike conventional keys, a smart key fob communicates with vehicle via radiofrequency signals. It's crucial to remember that your car is not spying on you. However, since the key fob emits these signals, it's possible for a criminal intercept them and take control of the vehicle. Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock the door or remotely open out of the trunk. This means that a hacker could be able to gain access to the system and take your vehicle. Smart car keys, however, send out an encrypted signal every time they perform this function. This makes them much more difficult to break, and makes them more difficult for thieves who are tech-savvy to exploit. Some vehicles also allow you to start your car by simply walking up to it and pressing the button. Contrary to traditional models which require you to insert and turn the key in order to start, these systems are powered by a key fob battery. The key fob will send an signal to the car's antenna to signal it that you're close, and the car can then activate its power doors and begin the engine.
