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 using radiofrequency waves.
If the smart key is in reach, the computer inside your car is able to recognize and verify the rolling code projected from the key fob prior to beginning the car. This helps to deter thieves.
Security
Many drivers are hesitant about the transfer of control of their vehicle to a virtual key on a smartphone with security being one of the most important concerns. The good news is that a smart car key can be used with the same security features as an ordinary fob.
Smart keys can lock and unlock the doors using fingerprint recognition. In order to use the feature, the driver needs to put their finger on the sensor located in or near the door handle or lock button (depending on the vehicle's configuration). This is similar to how a smartphone or tablet with an embedded fingerprint scanner works.
Smart keys can also help protect cars by not sending the exact frequency signal repeatedly. If a key sent the same signal each time it unlocked a door or remotely opened the trunk, this could allow thieves who are tech-savvy to hotwire vehicles and take them away. Smart keys emit a unique signal each time a trunk door is opened remotely.
Smart keys also protect vehicles from being taken by thieves at fuel stations and other parking areas. Smart keys transmit the signal at a low frequency that can only be detected by nearby smart keys, not by other objects or people that are not within the vehicle. This signal can be detected only within 10 cm of a smart key. This means it is impossible to steal your vehicle simply by taking the transmission.
Convenience
Smart keys eliminate the need to search through your pockets for keys or to lock the car using the remote control. You can unlock your car or start it by tapping on the app on your phone.
Smart keys, unlike traditional key fobs that emit an extremely low power signal that communicates with your car via radiofrequency signals. smart key car is equipped with an encrypted chip that the antenna in your vehicle detects. If you reach the of the car's range, it knows to unlock the doors and/or start the engine.
Some smart keys also store settings for the seat and mirrors as well as the steering wheel and allow you to change them with a single click. This feature is becoming more popular and a growing number of manufacturers are introducing it to their vehicles.
The market for automotive smart keys is growing due to the increasing demand for security features. These features help reduce wear on the ignition system of a car and ensure that only the driver is able to start or stop the engine. Smart keys also alert the driver if the battery is in low which makes it difficult for thieves to steal the car.
Certain systems will also allow you to open your doors from a distance when the battery for your smart key fails. It is recommended to keep a spare mechanical key hidden in your wallet or other safe.
Autonomy
Some smart key systems operate without a key fob that is in the pockets of the driver. Instead, they operate by pressing the trunk release or door handle. These systems also operate when a sensor detects that the driver is within.
The idea is to eliminate pressing a key fob while driving, allowing drivers to focus on driving safely and securely. The technology is already available in a few luxury cars and is gaining popularity with major automakers who are trying to meet customer demands.
While this feature provides convenience however, it can be a risk if the driver forgets to take their key fob out of the pocket prior to going into or out of the car. This is because smart key fobs emit an ultra-low-frequency signal that could be detected by a device that can unlock the doors or open the trunk. It's a tactic called a relay attack and it's been used by thieves who are tech-savvy to take vehicles from motorists at fuel stations, and even in parking garages.
However, many smart key systems come with an alternate method of opening and starting the vehicle in the event that the battery goes out. The driver typically has to place the dead key fob into a slot or hold it near a designated space in the cockpit, to trigger an emergency start system, which typically consists of an inductive coil that transmits energy from the key to the vehicle.
Safety
The smart key comes with an inbuilt security feature that locks the vehicle after you leave. It will also shut down the engine and unlock the trunk if it is discovered that you have left your keys inside. This will prevent you from being locked out of your vehicle in a hazardous location or while you run around.
In contrast to conventional keys, a smart key fob communicates with the vehicle via radiofrequency signals. It's important to remember that your car isn't spying on you. However, since the key fob transmits these signals, it's 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 open a door or remotely pop out the trunk. This means that a tech-savvy criminal could penetrate the system to take your vehicle. Smart car keys emit an encrypted code that changes every time they complete a function. This makes them harder to crack, and even more difficult for thieves who are tech-savvy to exploit.
Some vehicles also allow you to start your car by walking to it and pressing the button. Unlike traditional models that require you to insert and turn the key in order to start, these systems are powered by a key fob battery. The key fob sends an indication to your car's antenna, telling it that you're within. The vehicle will then activate the power doors, and start its engine.
