Smart Car Key Security Features

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

When the smart key is in reach, the computer inside your car recognizes and verifies the rolling code projected from the fob on the key before beginning the car. This helps deter thieves.

Security

Many drivers aren't keen to give control of their car to a virtual fob that is on a smartphone. Security is one of the major concerns. The good news is that a smart car key can be used with many of the same security features as the traditional fob.

Smart keys are able to lock and unlock the doors through fingerprint recognition. To access 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 configuration of the vehicle). This is similar to the way a smartphone or tablet with the fingerprint scanner inside works.

Another way that smart keys help keep cars secure is by not sending the same frequency signal over and over again. If a fob sent a signal each time it was unlocked or opened an trunk remotely, this could allow thieves to use hotwires to connect cars and take them away. Thankfully, this is not an issue because Smart Fortwo Key Fob keys emit a unique encrypted signal each time a door is opened or the trunk is remotely opened.

Smart keys also stop vehicles from being taken by thieves at fuel stations and other parking lots. This is because they send the signal at a low frequency that can be detected by the smart key in close proximity, however, not by any other person or objects outside of the vehicle. The signal can only be recognized within 10 cm of the smart key, meaning it is impossible for anyone to steal your car by stealing a transmission from a nearby fob.

In contrast to traditional key fobs which transmit a low-power signal, smart keys communicate with your vehicle using radiofrequency signals. The key fob comes with an encrypted chip that the antenna inside your car recognizes. When you are within range of your vehicle, it will open the doors or start the engine.

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

The market for automotive smart car key replacement cost keys is growing due to 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.

The idea is to eliminate the need to use a key fob while driving, so that drivers can concentrate on driving safely and in a secure manner. The technology is already present in a few luxury vehicles, and it's growing in popularity with mainstream automakers trying to keep up with the customer demand.

This feature is very convenient however, it could be risky if someone isn't careful to take the key fob out of their pocket prior to entering or leaving the vehicle. Because smart key fobs emit an low-frequency signal which can be detected by a different device that could open the doors or even the trunk. This is known as relay and has used by hackers to steal cars from fueling stations as well as parking lots.

However, the majority of smart key systems come with an alternative method of opening and re-starting the vehicle when the battery is dead. The driver usually must put the dead key fob in a slot or put it in a specific area of the cockpit to trigger an emergency starting system, which typically involves an inductive coil that transfers energy from the key to the car.

While it is important to keep in mind that your vehicle isn't spying on you however, the fact that the key fob transmits these signals makes it possible for a criminal to intercept them and gain control over the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock the door or remotely open out the trunk. This means that a cyber-savvy criminal could possibly infiltrate the system and take your vehicle. Smart car keys, however, put out an encrypted signal each time they perform this function. This makes them harder to hack and harder to exploit by tech-savvy thieves.

Certain vehicles allow you to start the car by walking towards it, pressing a button. Instead of traditional models that require you to insert and turn the key, these systems are powered by a key fob's battery. The key fob transmits an alert to the car's signal to inform it that you are close, and the vehicle can then activate its power doors and begin the engine.
