Smart Car Key Security Features

Smart keys communicate with your vehicle every day, whether in your pocket or on your desk. They communicate with each other through radiofrequency waves.

When the smart key is within distance, the computer in your car will recognize and verify the rolling code projected from the key fob before beginning the car. This helps thwart thieves.

Security

Many drivers are hesitant to give control of their car to a virtual fob via the phone. Security is among the primary 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, for instance, utilize fingerprint recognition to lock and unlock doors. To utilize the feature, the driver has to put their finger on the sensor that is placed near the door handle or lock button (depending on the car's configuration). This is similar to how a tablet or smartphone with a fingerprint scanner embedded operates.

A smart key replacement key can also help protect cars by not transmitting the exact frequency signal repeatedly. If a fob transmitted the same signal each time it opened a door, or remotely opened the trunk, this could allow thieves who are tech-savvy to hotwire vehicles and drive them away. Smart keys emit a unique signal each time a trunk door is opened remotely.

Smart keys also stop cars from being stolen by thieves at fuel stations and other parking lots. Smart keys send a low frequency signal that can only be detected by nearby smart keys, and not by any other objects that are not within the vehicle. The signal can be detected just within 10 cm of a Smart 450 key programming key. So, it's impossible to steal your vehicle simply by taking an engine.

Convenience

Using smart keys eliminates the need to dig through your pockets in search of the key or lock the car using remote controls. You can unlock your car and start it by tapping on the app on your smartphone.

Smart keys, in contrast to traditional keys that transmit an extremely low power signal, communicate with your car using radiofrequency waves. The key fob has an encrypted chip that the antenna in your car can recognize. When you are within reach of your vehicle it will unlock the doors and begin the engine.

Some smart keys can also save settings for the steering wheel, mirrors, and the seat. Then, you can change them by pressing a single button. This feature is becoming more popular, and a growing number of automakers are adding this to their vehicles.

The automotive smart key market is booming due to increasing demand for security and safety features. These features decrease wear on the ignition system of a car, and also ensure that only the owner can start or stop the engine. Smart keys can also inform the driver when the battery is running low, making it harder for thieves to take the car.

Some systems will also allow you to open your door at a distance if the battery of your smart key dies. It is recommended to keep a backup key in your wallet or a secure location.

Autonomy

Instead of the key fob which must be in the driver's pocket to open or start a car, smart key systems work when the door handle or the trunk release button is hit. These systems can be activated when a sensor detects the proximity of the driver.

The goal is to stop pressing a key fob during driving, allowing drivers to focus on driving safely and securely. The technology is currently available in certain luxury vehicles, and is growing in popularity with automakers that are trying to meet customer needs.

This feature is very convenient, but it can also be risky if someone does not remove the key fob from their pockets prior to entering or leaving the vehicle. Because smart key fobs emit a low-frequency signal that can be detected by a different device that can unlock the doors or open the trunk. It's a tactic called relay attack, and has been used by thieves with a technological advantage to take cars from drivers at fueling stations, as well as parking areas.

Most smart key systems do include a backup mechanism for starting and opening the vehicle in the case of a dead battery. The driver is required to put the dead key fob in a slot or hold it near a special area in the cockpit to trigger an emergency start system, which is usually an inductive coil that transfers energy from the key to the vehicle.

Safety

The smart key has integrated security features which locks the vehicle when you leave. The smart key can close the vehicle and unlock the trunk the keys remain inside. This will stop you from being locked out of your vehicle in a dangerous location or when you are running the errands.

In contrast to conventional keys, a smart key fob can communicate with the vehicle using radiofrequency signals. While it is important to keep in mind that your vehicle isn't spying on your, the fact that the key fob transmits these signals makes it possible for criminals to steal them and gain control over the vehicle.

Open Road Auto Group explains that traditional key fobs transmit the same frequency signal every time they unlock the door or remotely open the trunk. This means that a tech-savvy criminal could be able to hack into the system to steal your vehicle. Smart car keys, however, send out an encrypted signal every time they use this function. This makes them more difficult to hack and harder to exploit by tech-savvy thieves.

Some vehicles also allow you to start your car by simply walking to it and pressing the button. These systems, in contrast to traditional models that require you to insert and turn the keys and are powered by key fob batteries. The key fob transmits a signal to the car's antenna to signal it that you're close, and the car will then be able to open its power doors and start the engine.
