Smart Car Key Security Features

Smart keys communicate with your vehicle all the time, whether in your pocket or on your desk. They communicate with radiofrequency waves.

When the smart key is within range, a computer in your car recognizes the rolling code projected by the key fob and verifies it before beginning the engine. This helps to deter thieves.

Security

Many drivers are skeptical about the transfer of control of their vehicle to a virtual key on a smartphone, with security being among the most important concerns. The good news is a smart key comes with many of the same features as a traditional car fob.

Smart keys are able to lock and unlock the doors by using fingerprint recognition. To utilize the feature, a person must place their finger on a sensor located close to or in the vicinity of the lock button or door handle (depending on the configuration of the vehicle). This is similar to the way a tablet or smartphone that has a fingerprint scanner embedded functions.

A smart key fob key could also help to protect vehicles by not sending the exact frequency signal repeatedly. If a fob transmitted the same signal every time it unlocked the door remotely or opened the trunk, it would permit thieves with a tech-savvy mindset to wire vehicles and take them away. Smart keys emit a different signal every time a trunk or door is opened remotely.

smart car spare key keys also help prevent cars from being taken away by thieves at fuel stations and other parking lots. Smart keys send the signal at a low frequency that can only be picked up by nearby smart keys, not by objects or individuals outside the vehicle. The signal can only be detected within 10 centimeters of the smart key, which means it is not possible for anyone to steal your car just by picking up a signal from a fob that is nearby.

Convenience

Smart keys will no longer require you to dig through your pockets to find a key or even lock the car with remote. Instead, you can tap your phone in the app to unlock or start the engine, and then drive away!

Smart keys, unlike traditional key fobs that transmit an extremely low power signal and communicate with your car through radiofrequency waves. The key fob comes with an encrypted chip that the antenna inside your car can recognize. When you get within of the car's range, it knows to unlock the doors and/or begin the engine.

Some smart keys can also save settings for the seat, mirrors and steering wheel which allows you to adjust them using just one button. This feature is becoming more popular and a rising number of manufacturers are incorporating it to their automobiles.

The automotive smart key market is growing due to the increasing demand for safety and security features. These features reduce wear on the ignition system of a vehicle and ensure that only the driver has the ability to start or stop the engine. Moreover, smart keys can also notify the driver that the battery is running low and make it harder for thieves to take the vehicle.

Some systems will allow you to unlock your door from a distance in the event that the battery in your smart key goes out. It is best to keep a backup mechanical key in your wallet or another safe place.

Autonomy

Certain smart key systems function without a key fob in the pockets of the driver. Instead, they function by pressing the trunk release or door handle. These systems can also be activated if a sensor detects the proximity of the driver.

The idea is to eliminate the necessity of pressing a key fob when driving, so drivers can concentrate on driving safely and securely. The technology is already in use in some luxury vehicles and it's gaining popularity among major automakers who are trying to keep up with the customer demand.

This feature is convenient however, it could be risky if a driver fails to remove the key fob from their pockets prior to leaving or entering the vehicle. The reason is that smart key fobs emit a low-frequency signal that can be picked up by a device that can unlock the doors or open the trunk. It's a tactic called relay attack, and it has been used by thieves with a technological advantage to take vehicles from motorists at fueling stations and also in parking lots.

Most smart key systems do include a backup mechanism for starting and opening the vehicle in the event of the battery being dead. The driver typically has to place the dead key in the slot or place it in a designated area in the cockpit to trigger an emergency start system, which typically consists of an inductive coil that transfer energy from the key to the car.

Safety

The smart key comes with integrated security features that locks the vehicle once you leave. The smart key fob key will stop the vehicle from being operated and open the trunk the keys remain in the trunk. This will keep you from being locked out of your vehicle in an unsafe location or while you run around.

Smart key fobs communicate with vehicles via radiofrequency signals, unlike conventional keys. While it's important to keep in mind that your vehicle isn't spying on you however, the fact that the key fob sends these signals makes it possible for criminals to intercept them and gain control of the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal every time they unlock the door or remotely open out of the trunk. This means that a cyber-savvy criminal can potentially hack into the system to take your vehicle. Smart car keys emit an encrypted code that is different every time they complete an action. This makes them harder to break and more difficult to be exploited by smart thieves.

Certain vehicles allow you to start your car by walking towards it and pressing the button. Unlike 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 a signal to your car's antenna, letting it know that you're within. The car will activate the power doors, and begin its engine.
