Smart Car Key Security Features Smart keys communicate with your car continuously, whether they're in your pocket or on your desk. They communicate via radiofrequency waves. If the smart key is within reach, the computer inside your car is able to recognize and verify the rolling code projected from the fob of your key before getting the car started. This helps deter thieves. Security Many drivers are hesitant to hand over control of their vehicle to a virtual fob on a smartphone. Security is among the most important concerns. The good news is that a smart car key can be used with many of the same security features as an ordinary fob. For starters, smart keys use fingerprint recognition to lock and unlock doors. To utilize the feature, the user must place a finger on the sensor that is placed near the door handle or the lock button (depending on the car's configuration). This is similar to how a phone or tablet equipped with an embedded fingerprint scanner functions. A smart key can also make cars safer by not sending the same frequency signal repeatedly. If a fob sent the same signal each time it locked a door or remotely opened the trunk, this could allow tech-savvy thieves to use hotwires to make them disappear. Thankfully, this is not an issue since smart keys emit a distinct encrypted signal every time doors are opened or the trunk is remotely opened. Smart keys also can help prevent cars being stolen at gas stations or other parking areas. This is because they send an extremely low-frequency signal that could be picked up by the proximity of a smart key, however, not by any other person or objects that are not within the vehicle. The signal can only be detected within 10 centimeters of the smart key, so it is not possible for someone to steal your car just by grabbing a transmission from a nearby fob. Convenience Smart keys eliminate the need to rummage through your pockets to find keys or to lock your car using a remote control. You can unlock your car or begin it by tapping the app on your phone. Contrary to traditional key fobs which 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 car can recognize. If you're within proximity to your vehicle, it will open the doors or start the engine. Some smart keys can also store settings for the seats, mirrors and steering wheel and allow you to change them by pressing a single button. This feature is becoming more popular and a growing number of manufacturers are incorporating it to their automobiles. The industry of automotive smart keys is booming because of the increasing demand for safety features. These features decrease wear and tear on a car's ignition system and ensure that the driver is the only person who has the ability to stop or start the engine. Smart keys also alert the driver if the battery is not fully charged which makes it difficult for thieves to steal the vehicle. Some systems will also allow you to open your door from a distance in the event that the battery in your smart key goes out. But, it's better to have a spare mechanical key that you can keep in your wallet or somewhere else secure. Autonomy Instead of the key fob which must be carried by the driver to unlock or start a car, some smart key systems function when the car door handle or the trunk release button is hit. They also function when a sensor senses the driver is nearby. The idea is to remove the necessity of pressing a key fob button while driving, so that drivers can concentrate on driving safely and securely. The technology is available in some premium vehicles, and it's becoming popular among major automakers who are trying to keep up with customer demand. Although this feature is convenient however, it can also be dangerous If the driver isn't careful to take their key fob from the pocket prior to leaving or entering the vehicle. This is because 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 what's known as relay, and it's been used by cyber-savvy criminals to steal cars at fuel stations and parking spaces. However, the majority of smart key systems include a backup method for opening and starting the vehicle in the event that the battery goes out. The driver is required to put the dead key in the slot or place it near a special space in the cockpit, to trigger an emergency starting system, which usually involves an inductive coil that transfers energy from the key to the vehicle. Safety The smart key comes with a built-in security feature that locks your vehicle when you leave. It will even shut down the engine and open the trunk if you have locked the keys inside. This will prevent you from being locked out of your car in a dangerous location or when running an errand. Smart key fobs communicate with vehicles using radiofrequency signals, which is different from conventional keys. It's important to remember that your car isn't watching you. However, since the key fob transmits these signals, it's possible for a criminal to intercept the signals and then 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 of the trunk. This means that a criminal with a technological edge could be able to gain access to the system and steal your vehicle. Smart car keys, however, send out an encrypted signal that is different each time they perform this function. This makes them much harder to break, and makes them more difficult for thieves who know how to take advantage of. Certain vehicles allow you to start the car by walking right up to it and pressing a button. In smart car key programmer G28 to traditional models that require you to insert and turn the key and then turn it on, these systems are powered by a key fob's battery. The key fob sends the car's antenna, telling it that you're in close proximity. The car will activate the power doors and start its engine.
