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.

If the smart key is in the range of the computer in your car is able to recognize and verify the rolling code projected from the key fob before beginning the engine. This helps to deter thieves.

Security

Many drivers are hesitant to give control of their vehicle to a virtual fob via an iPhone. Security is among the primary concerns. The good news is that the smart car key comes with the same security features as a traditional fob.

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

Smart keys can also ensure the safety of vehicles by not transmitting the exact frequency signal repeatedly. If a key sent the same signal each time it unlocked a door, or remotely opened the trunk, this would allow tech-savvy thieves to wire vehicles and take them away. Thankfully, this is not a problem because smart keys emit a different encrypted signal each time the door is opened or the trunk is remotely opened.

Smart keys can also prevent cars being stolen at gas stations and other parking spots. This is because they send a low-frequency signal that can be picked up by a nearby smart car key coding key, but not by people or objects that are not within the vehicle. The signal is detectable only within 10 centimeters of the smart key. Thus, it is impossible to steal your vehicle simply by taking a transmission.

Convenience

Smart keys eliminate the need to search through your pockets for a key, or lock the car using remote. You can unlock your car and start it by tapping the app on your smartphone.

Unlike traditional key fobs, that transmit a low-power signal, smart keys communicate with your vehicle through radiofrequency waves. The key fob contains an encrypted chip which the antenna in your vehicle recognizes. When you get within proximity to your car it is able to open the doors and/or start the engine.

Some smart keys also store settings for the seat, mirrors and steering wheel, allowing you to set them by pressing a single button. This feature is becoming increasingly popular and a growing number of manufacturers are introducing it how to unlock a smart car without a key their vehicles.

The automotive smart key market is growing rapidly due to the rising demand for security and safety features. These features reduce wear on the ignition system of a car and ensure that only the owner can start or stop the engine. Moreover, smart keys can also notify the driver when the battery is low, which makes it less difficult for thieves to steal the vehicle.

Some systems let you unlock the door remotely in the event that your smart key battery goes out. It is recommended to have a backup mechanical key hidden in your wallet or in a safe place.

Autonomy

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

The idea is to eliminate the necessity of pressing a key fob button while driving, allowing drivers to concentrate on driving safely and secure. The technology is available in some high-end vehicles, and is gaining traction among mainstream automakers trying to keep up with customer demand.

Although this feature is convenient but it could be risky in the event that the driver does not take their key fob from the pocket before leaving or entering the vehicle. That's because smart key fobs emit an ultra-low-frequency signal that could be detected by a device that could open the doors or pop the trunk. This is a tactic known as a relay attack and it's been employed by tech-savvy thieves to steal cars from drivers at fuel stations, as well as parking spaces.

However, the majority of smart car key reprogramming key systems come with a backup method for opening and restarting the vehicle if the battery dies. The driver must usually place the dead key in an opening or keep it near a special area of the cockpit to trigger an emergency starting system, which is usually an inductive coil that transfers energy from the key to the vehicle.

Safety

The smart key comes with integrated security features 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 the keys inside. This will prevent you from being locked out of your car in an area where it is unsafe or while completing errands.

As opposed to traditional keys, a smart key fob can communicate with the vehicle via radiofrequency signals. It's important to keep in mind that your car isn't spying on you. However, since the key fob sends out these signals, it's possible for a criminal intercept them and take control of the vehicle.

Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they open the door or remotely pop the trunk. This means that a criminal with a technologically advanced mind could be able to infiltrate the system and steal your vehicle. Smart car keys, however, put out an encrypted signal each time they do this. This makes them difficult to break and more difficult to exploit by hackers.

Certain vehicles let you start the vehicle by walking up to it and pressing the button. These systems, in contrast to traditional models that require you insert and turn the keys, are powered by key fob batteries. The key fob transmits a signal to the car's signal to tell it that you are close to the vehicle, and it will then be able to open its power doors and begin the engine.
