Smart Car Key Security Features

Smart keys communicate with your car every day, whether in your pocket or on your desk. They communicate via radiofrequency waves.

Security

Many drivers are reluctant to give control of their vehicle to a virtual fob on an iPhone. Security is one of the most important concerns. The good news is a smart key comes with many of the same features that a traditional car fob does.

For starters, smart keys make use of fingerprint recognition to lock and unlock doors. In order to use the feature, the driver needs to place a finger on the sensor located in or near the door handle or the lock button (depending on the vehicle configuration). This is similar to how smartphones and tablets with an embedded fingerprint scanner works.

Another way that smart keys help keep cars safe is by not sending the same frequency signal repeatedly again. If a fob broadcasted the same signal every time it unlocked a door or remotely opened the trunk, it could permit thieves with a tech-savvy mindset to connect vehicles to hot wires and take them away. Smart keys emit a different signal each time a trunk or door is opened remotely.

Smart keys can also help to stop cars from being stolen at gas stations or other parking spaces. They transmit an extremely low-frequency signal that could be detected by an adjacent smart key but not by other people or objects outside of the vehicle. The signal can be detected within 10 centimeters of the smart key. Therefore, it is not possible for anyone to steal your car just by picking up a signal from a fob that is nearby.

Smart keys, in contrast to traditional key fobs that emit the signal with low power they communicate with your car using radiofrequency signals. The key fob has an encrypted chip which the antenna in your vehicle recognizes. If you reach the range of your car it will open the doors and/or start the engine.

Some smart keys can also save settings for the steering wheel, mirrors and seat. You can then alter them by pressing one button. This feature is becoming more popular, and a growing amount of manufacturers are adding this to their vehicles.

The market for car smart car replacement key keys is growing rapidly due to the rising demand for security and safety features. These features help reduce the wear and tear on the ignition system of a car and ensure that the driver is the sole person who has the ability to stop or start the engine. Furthermore, smart keys also notify the driver if the battery is not fully charged making it more difficult for thieves to steal the vehicle.

Certain systems also allow you to open your door from a distance when the smart key battery dies. However, it's advisable to have a spare mechanical key that is hidden in your wallet or somewhere else safe.

Autonomy

Instead of an actual key fob that needs to be carried by the driver to unlock or start a car, smart key systems operate when the car door handle or the button for trunk release is pressed. These systems also operate when a sensor detects that the driver is near.

The idea is to avoid pressing a key fob when driving, so that drivers can focus on driving safely and secure. The technology is present in a few premium cars and is getting more popular with major automakers who are trying to meet customer needs.

This feature is convenient however it can be risky if the driver fails to take the key fob out of their pocket before entering or leaving the vehicle. Smart key fobs emit low-frequency signals that could be picked up by other devices that can unlock doors or open the boot. This is a technique called relay, and it's used by hackers to steal cars from fueling stations as well as parking spaces.

The majority of smart key systems come with a backup method to open and start the vehicle in the case of an insufficient battery. The driver must usually place the dead key fob inside an opening, or keep it near to a designated area in the cockpit to start the emergency starter.

However, since the key fob emits these signals, it is possible for criminals to intercept these signals and control the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock a door or remotely pop out the trunk. This means that a criminal with a technological edge could possibly infiltrate the system and take your vehicle. Smart car keys, however, put out an encrypted signal that is different each time they do this. This makes them more difficult to hack and harder to be exploited by thieves with a technological edge.

Certain vehicles let you start the vehicle by walking up to it, pressing the button. These systems, in contrast to conventional models that require you insert and turn the keys and are powered by key fob batteries. The key fob transmits a signal to your car's antenna, letting it know that you're within. The vehicle will then activate the power doors, and start its engine.
