Smart Car Key Security Features

Smart keys communicate with your car continuously, whether they're in your pocket or on your desk. They communicate by using radiofrequency signals.

If the smart key is within range, the computer in your car recognizes and verifies the rolling code projected from the key fob prior to beginning the engine. This helps deter thieves.

Security

Many drivers are reluctant to hand over control of their vehicle to a virtual fob via a smartphone. Security is one of the most important concerns. The good news is a smart key can provide many of the same features as a traditional car fob.

Smart keys lock and unlock the doors through fingerprint recognition. To make use of this feature, the driver has to place their finger on the sensor close to the lock button or door handle (depending on the vehicle's configuration). This is similar to the way a tablet or smartphone with a fingerprint scanner integrated operates.

A smart key can make cars safer by not sending the exact frequency signal repeatedly. If a fob transmitted the same signal each time it opened a door, or remotely opened the trunk, this would permit thieves with a tech-savvy mindset to wire vehicles and take them away. Fortunately, this isn't an issue because smart keys emit a distinct encrypted signal each time doors are opened or the trunk is remotely opened.

Smart keys also help in preventing theft of cars at gas stations or other parking spots. This is because they send the signal at a low frequency that can be picked up by the proximity of a smart key, but not by other people or objects outside of the vehicle. The signal is only identified within 10 cm of the smart key, so it is not possible for someone to steal your car by picking up a signal from a fob that is nearby.

Convenience

Using smart keys eliminates the need to rummage through your pockets to locate a key or to secure your car using remote controls. You can unlock your car or begin it by tapping the app on your phone.

As opposed to traditional key fobs that transmit a low-power signal smart keys connect to your vehicle via radiofrequency waves. The key fob comes with an encrypted chip that the antenna inside your car can recognize. If you are within the reach of your vehicle it will open the doors or start the engine.

Some smart keys can also store settings for the seats mirrors, the steering wheel and seat that allow you to alter them with just one button. This feature is becoming increasingly popular and a growing number of manufacturers are incorporating it to their automobiles.

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

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

Autonomy

Instead of an actual key fob that needs to be kept in the pocket of the driver to open or start a car, smart key systems function when the door handle or the trunk release button is pressed. These systems can also be activated if a sensor detects that a driver is near.

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

This feature is convenient however, it could be dangerous if a driver forgets to remove the key fob from their pocket prior to entering or leaving the vehicle. smart key for car key fobs emit low-frequency signaling that can be detected by other devices that open doors or pop the boot. This is a technique called a relay, and it's been used by cyber-savvy criminals to steal cars at fueling stations as well as parking lots.

However, most smart car key fob programming key systems include a backup method for opening and starting the vehicle in the event that the battery fails. The driver must usually place the dead key fob into a slot or hold it near a special area of 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 an inbuilt security feature which locks the vehicle when you leave. The smart key can stop the vehicle from being operated and unlock the trunk even the keys remain in the trunk. This will prevent you from being locked out of your car in a dangerous area or while you run errands.

Unlike conventional keys, a smart key fob can communicate with the vehicle via radiofrequency signals. While it is vital to keep in mind that your vehicle isn't spying, the fact that the key fob transmits these signals makes it possible for criminals to intercept these signals and gain control over 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 implies that a hacker could penetrate the system to steal your vehicle. Smart car keys emit a different encrypted code every time they complete a function. This makes them harder to penetrate and more difficult to be exploited by thieves with a technological edge.

Certain vehicles allow you to 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 they are powered by key fob batteries. The key fob sends an alert to the car's antenna signal it that you're near, and the car smart key can then turn on its power doors and start the engine.
