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 within the range of the computer inside your car recognizes the rolling code projected by the fob of the key and verifies it before starting the engine. This helps deter thieves.
Security
Many drivers are hesitant to give control of their vehicle to a virtual fob on a smartphone. Security is one of the main concerns. The good news is that the smart car key comes with the same security features as a traditional fob.
Smart keys unlock and lock the doors by using fingerprint recognition. To utilize the feature, the driver needs to place a finger on a sensor placed in or near the door handle or the lock button (depending on the configuration of the vehicle). This is similar to how a tablet or smartphone with a fingerprint scanner embedded functions.
smart car key not working can also help protect cars by not sending the exact same frequency signal repeatedly. If a smart key sends an individual signal each time it was unlocked or opened a trunk remotely, it would enable tech-savvy thieves connect cars to hotwires and eliminate them. Smart keys emit a unique signal each time a trunk door is opened remotely.
Smart keys also protect cars from being taken away by thieves at fueling stations as well as other parking spots. This is because they transmit a low-frequency signal which can be detected by the proximity of a smart key, but not by people or objects outside of the vehicle. The signal can be recognized within 10 cm of the smart key. Therefore, it is virtually impossible for someone to steal your car just by picking up a transmission from a fob that is nearby.
Convenience
Smart keys eliminate the need to rummage through your pockets to locate a key or to secure your car using a remote control. You can unlock your car or start it by pressing the app on your phone.
Unlike traditional key fobs, that transmit a low-power signal, smart keys communicate with your vehicle using radiofrequency signals. The key fob has an encrypted chip that the antenna inside your car can recognize. If you are within the distance of your vehicle, it will open the doors and start the engine.
Certain smart keys also save settings for the steering wheel, mirrors and seat. Then, you can change them by pressing one button. This feature is becoming increasingly popular, and a greater number of manufacturers are incorporating this feature to their vehicles.
The market for car smart keys is growing because of the increasing demand for security and safety features. These features reduce the wear and tear on the ignition system of a vehicle and ensure that only the driver has the ability to start or stop the engine. Smart keys can also alert the driver when the battery is not fully charged which makes it difficult for thieves to take the car.
Some systems let you open the door from a distance if your smart key battery goes out. However, it's best to have a spare mechanical key hidden in your wallet or somewhere in a safe place.
Autonomy
Some smart key systems operate without a key-fob in the driver's pockets. Instead, they function by pressing the trunk release or door handle. These systems can also be activated if a sensor detects a driver's proximity.
The idea is to eliminate the necessity of pressing the 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 mainstream automakers who are working to meet consumer demands.
This feature is convenient, but it can also be risky if someone does not take the key fob out of their pockets prior to leaving or entering the vehicle. This is because smart key fobs emit low-frequency signals that can be detected by a different device that could open the doors or even the trunk. This is what's known as relay, and it's used by hackers to steal cars from fuel stations and parking lots.
Most smart key systems do have a backup system to start and open the vehicle in the case of the battery being dead. The driver is required to place the dead key in an opening, or keep it near a designated area in the cockpit to trigger the emergency starting system. This typically involves an inductive coil that transfers energy from the car to the key.
Safety
The smart key comes with built-in security features which locks the vehicle when you leave. The smart key can shut down the car and open the trunk when the keys are inside. This prevents you from getting locked out of your vehicle in an area that is not safe or while completing the errands.
Smart key fobs communicate with vehicles via radiofrequency signals, unlike conventional keys. It's important to remember that your car isn't watching you. However, since the key fob broadcasts these signals, it is possible for a criminal to intercept them and take control of the vehicle.
Open Road Auto Group explains that traditional key fobs transmit the same frequency signal each time they unlock the door, or remotely open the trunk. This means a tech-savvy criminal could potentially infiltrate the system and take your vehicle. Smart car keys, however, put out an encrypted signal each time they are used. This makes them much harder to break, and makes them more difficult for thieves who are tech-savvy to gain access to.
Certain cars allow you to start the car by walking right up to it and pressing a button. Instead of 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 an alert to your car's antenna, letting it know that you're close. The car will activate the power doors, and start its engine.
