Smart Car Key Security Features Smart keys communicate with your vehicle all the time, whether in your pocket or on your desk. They talk to each other by using radiofrequency signals. If the smart key is within range, a computer in your vehicle detects the rolling code projected by the fob of the key and confirms it prior to starting the engine. This helps deter thieves. Security Many drivers are reluctant to give control of their car to a virtual fob on smartphones. 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 the traditional fob. Smart keys are able to lock and unlock the doors by using fingerprint recognition. To use this feature, the driver has to place their finger on a sensor close to or in the vicinity of the door knob or lock handle (depending on vehicle configuration). g28carkeys.co.uk is similar to how a tablet or smartphone that has the fingerprint scanner inside operates. Smart keys can also help protect cars by not sending the same frequency signal repeatedly. If a fob transmitted the same signal every time it locked doors or remotely opened the trunk, it could let thieves who are adept at technology to use hotwires to remove them. Smart keys emit a unique signal each time a trunk or door is opened remotely. Smart keys also help to stop cars from being stolen at gas stations and other parking spaces. They transmit a low-frequency signal that can be detected by a nearby smart key, but not by people or objects that are not within the vehicle. The signal can be detected just within 10 cm of the smart key. So, it's impossible to steal your vehicle simply by taking an engine. Convenience Using smart keys eliminates the need to search through your pockets to find a key or to lock your car using a remote control. You can unlock your car or start it by tapping the app on your smartphone. In contrast to traditional key fobs which transmit a low-power signal, smart keys connect to your vehicle using radiofrequency signals. The key fob is equipped with an encrypted chip that the antenna in your car can recognize. Once you're within of the car's range it is able to open the doors and/or start the engine. Some smart keys also store settings for the seat mirrors, the steering wheel and seat and allow you to change them with a single click. This feature is becoming increasingly popular and a rising number of companies are adding it to their vehicles. The market for automotive smart keys is booming because of the increasing demand for safety features. These features minimize the wear and tear of 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 when the battery is in low which makes it difficult for thieves to steal the vehicle. Some systems let you open the door remotely if your smart key battery runs out. It is recommended to keep a spare mechanical key in your wallet, or in a safe place. Autonomy Instead of the key fob which must be in the driver's pocket to open or start a car, smart key systems operate when the car door handle or the button for trunk release is pressed. These systems can also be activated when an sensor detects the driver's proximity. The idea is to eliminate the need to use a key fob while driving so that drivers can focus on driving safely and secure. The technology is already available in some premium vehicles, and it's becoming popular among major automakers who are trying to keep pace with customer demand. Although this feature is convenient however, it can also be dangerous in the event that the driver does not take their key fob out of the pocket before going into or out of the car. That's because smart key fobs emit a low-frequency signal that can be detected by a device that could open the doors or even the trunk. It's a tactic called a relay attack and it's been employed by thieves who are tech-savvy to take vehicles from motorists at fueling stations as well as in parking garages. Most smart key systems do include a backup mechanism for opening and starting the vehicle in the case of the battery being dead. The driver must usually place the dead key in a slot or put it in a specific 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 has an integrated security feature that locks your vehicle after you leave. The smart key will shut down the car and unlock the trunk when keys are inside. This helps you avoid being locked out of your vehicle in an area where it is unsafe or while completing on errands. Smart key fobs communicate with vehicles via radiofrequency signals, unlike traditional keys. While it's important to keep in mind that your vehicle isn't spying on you, the fact that the key fob transmits these signals makes it possible for criminals to intercept these signals and gain control of the vehicle. Open Road Auto Group explains that traditional key fobs emit the same frequency signal every time they unlock the door or remotely open the trunk. This means that a cyber-savvy criminal could be able to infiltrate the system and take your vehicle. Smart car keys emit a different encrypted code every time they perform a function. This makes them harder to crack, and even more difficult for tech-savvy thieves to exploit. Some vehicles also allow you to start your car by walking up to it and pressing a button. Unlike traditional models that require you to insert and turn the key, these systems are powered by a key fob's battery. The key fob transmits a signal to the car's antenna to signal it that you're close, and the vehicle can then turn on its power doors and begin the engine.
