Smart Car Key Security Features

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

When the smart key is within reach, the computer inside your car is able to recognize and verify the rolling code projected from the key fob prior to beginning the engine. This helps to deter thieves.

Security

Many drivers aren't comfortable giving control of their vehicle to a virtual key on a smartphone, with security being among the main concerns. The good news is that a smart key fob car key can be used with much of the same security features as traditional fobs.

Smart keys can lock and unlock the doors by using fingerprint recognition. To utilize the feature, the driver must put their finger on the sensor near the door handle or the lock button (depending on the vehicle's configuration). This is similar to how a smartphone or tablet with an embedded fingerprint scanner functions.

A smart key replacement key can also ensure the safety of vehicles by not transmitting the exact frequency signal repeatedly. If a fob broadcasted the same signal each time it unlocked the door remotely or opened the trunk, it could let thieves who are adept at technology to wire vehicles and take them away. Fortunately, this isn't an issue since smart keys emit a different encrypted signal each time an opening is made on a door or the trunk is opened remotely.

Smart keys can also help to stop cars from being stolen at gas stations or other parking areas. This is because they send the signal at a low frequency that can be detected by the smart key in close proximity, but not by other people or objects outside of the vehicle. The signal can only be identified within 10 cm of the smart key, so it is difficult for anyone to steal your car by stealing a transmission from a nearby fob.

Convenience

Smart keys eliminate the need to dig through your pockets to locate the key or lock the car using a remote control. Instead, just tap on your smartphone in the app to unlock or start the engine and go on your way!

In contrast to traditional key fobs which transmit a low-power signal, smart keys connect to your vehicle through radiofrequency waves. The key fob has an encrypted chip that the antenna in your car recognizes. When you are within 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 set them by pressing a single button. This feature is becoming more popular, and a greater amount of manufacturers are adding this feature to their vehicles.

The automotive smart key market is growing due to the increasing demand for safety and security features. These features decrease wear on the ignition system of a car, and also ensure that only the driver is able to start or stop the engine. Smart keys also alert the driver when the battery is running low and make it more difficult for thieves to take the car.

Certain systems allow you to open the door remotely if your smart key battery goes out. It is best to keep a spare mechanical key in your wallet or another safe location.

Autonomy

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

The idea is to eliminate the need to press the key fob button while driving, so that drivers can concentrate on driving safely and securely. The technology is already in use in some premium vehicles, and it's becoming popular among mainstream automakers that are trying to keep up with customer demand.

This feature is convenient however it can be risky if a driver isn't careful to take the key fob out of their pockets prior to entering or leaving the vehicle. Smart key fobs emit low-frequency signaling that could be picked up by other devices that open doors or crack the boot. This is a technique called relay, and it's been used by tech-savvy criminals to steal cars at fueling stations as well as parking lots.

However, many smart key systems offer a backup method for opening and re-starting the vehicle if the battery dies. The driver is required to place the dead key in an opening, or keep it near a designated space in the cockpit to activate the emergency starting system. This usually involves an inductive coil that transfers energy from the key to the car.

Safety

The smart key has a built-in security feature that will lock your vehicle when you leave. It will even shut down the engine and open the trunk if you have left the keys inside. This will prevent you from being locked out of your vehicle in a dangerous location or while you run around.

Smart key fobs connect to vehicles using radiofrequency signals, in contrast to conventional keys. While it's crucial to be aware that your vehicle isn't spying on you, the fact that the key fob sends these signals allows criminals to intercept these signals and gain control of the vehicle.

Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they open the door or remotely open out the trunk. This means that a cyber-savvy criminal could be able to infiltrate the system and take your vehicle. Smart car keys, however, send out an encrypted signal that is different each time they perform this function. This makes them harder to hack, and also more difficult for thieves with a technological edge to gain access to.

Certain vehicles let you start the car by walking right up to it, and pressing the button. In contrast to traditional models that require you to insert and turn the key to start the engine, these systems are powered by a key fob's battery. The key fob sends a signal to the car's signal to tell it that you are close, and the car can then activate its power doors and begin the engine.
