Smart Car Key Security Features A smart key communicates with your vehicle on a constant basis 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 in your car recognizes the rolling code projected by the fob of the key and verifies it before starting the engine. This helps to deter thieves. Security Many drivers are hesitant about handing control of their vehicle to a virtual key on 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 are able to lock and unlock the doors with fingerprint recognition. To use the feature, a driver must place their finger on a sensor in or near the door knob or lock handle (depending on the vehicle's configuration). This is similar to how a smartphone or tablet with a fingerprint scanner integrated operates. A smart key could also help protect cars by not sending the same frequency signal repeatedly. If a fob broadcasted the same signal every time it locked a door, or remotely opened the trunk, this could allow tech-savvy thieves to use hotwires to make them disappear. Fortunately, this isn't an issue because smart keys emit a unique encrypted signal each when an opening is made on a door or the trunk is opened remotely. Smart keys also protect the theft of cars by thieves at fueling stations and other parking areas. Smart keys transmit a low frequency signal that can only be detected by nearby smart keys, and not by people or other objects outside the vehicle. This signal can be detected at a distance of 10 cm from a smart key. This means it is impossible to steal your vehicle simply by taking the transmission. replacement smart car key Using smart keys eliminates the need to fumble through your pockets to locate keys or lock the car using the remote control. Instead, simply tap your phone in the app to unlock the car or start the engine, and then drive away! As opposed to traditional key fobs that transmit a low-power signal smart keys communicate with your car via radiofrequency waves. The key fob has an encrypted chip that the antenna inside your car recognizes. If you are within the range of your vehicle, it will unlock the doors or start the engine. Certain smart keys also save settings for the steering wheel, mirrors, and seats. Then, you can change them by pressing a single button. This feature is becoming more popular, and an increasing number of manufacturers are incorporating this to their vehicles. The market for automotive smart keys is growing rapidly due to the growing demand for safety features. These features help reduce wear and tear on the ignition system in a car and ensure that the driver is the only person who can stop or start the engine. Smart keys also notify the driver if the battery is running low and make it more difficult for thieves to steal the car. Some systems allow you to open the door from a distance if your smart key battery goes out. It's best to keep a mechanical backup key in your wallet or another safe place. 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 car door handle or the trunk release button is hit. These systems also operate when a sensor detects that the driver is in close proximity. The idea is to eliminate the need to use a key fob while driving so that drivers can concentrate on driving safely and secure. The technology is present in a few premium cars and is becoming popular among automakers of all kinds who are trying to meet customer requirements. While this feature can be useful, it can be dangerous If the driver isn't careful to take their key fob out of the pocket before leaving or entering the vehicle. Smart key fobs emit low-frequency signals which can be picked up by other devices that can unlock doors or open the boot. It's a tactic called a relay attack and it's been employed by tech-savvy thieves to steal vehicles from motorists at fueling stations, and even in parking garages. However, the majority of smart key systems have an alternative method of opening and re-starting the vehicle in the event that the battery goes out. The driver is required to put the dead key fob in a slot or hold it near a designated area in the cockpit to trigger an emergency starting system, which usually involves an inductive coil that transmits energy from the key to the vehicle. Safety The smart key has a built-in security feature that locks the vehicle after you leave. It will even shut down the engine and open the trunk if you have left the keys inside. This prevents you from getting locked from your car in an unsafe location or while completing errands. Smart key fobs can communicate with vehicles through radiofrequency signals, unlike traditional keys. It is important to remember that your car is not monitoring you. However, since the key fob transmits these signals, it is possible for a criminal to 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 doors or remotely pop out of the trunk. This means that a tech-savvy criminal can potentially penetrate the system to take your vehicle. Smart car keys emit an encrypted code that is different every time they perform the task. This makes them harder to crack, and more difficult for tech-savvy thieves to take advantage of. Certain cars allow you to start the vehicle by walking up to it and pressing the button. Unlike 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 your car's antenna, telling it that you're close. The car will open the power doors and begin its engine.
