Smart Car Key Security Features

Smart keys communicate with your vehicle continuously, whether they're in your pocket or on your desk. They communicate with one another through radiofrequency waves.

When the smart key for cars key is in the range of the computer in 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 are reluctant to give control of their vehicle to a virtual fob on a smartphone. Security is among the major concerns. The good news is that a smart car key has all of the security features as the traditional fob.

For starters, smart keys utilize fingerprint recognition to lock and unlock doors. To utilize the feature, the driver has to place a finger on the sensor that is placed near the door handle or the lock button (depending on the vehicle configuration). This is similar to how a phone or tablet with an embedded fingerprint scanner function.

A smart key can also make cars safer by not transmitting the exact frequency signal repeatedly. If a key sent a signal every time it unlocked or opened the trunk remotely, this allows thieves with a technological advantage to use hotwires to connect cars and take them away. Smart keys emit a distinct signal every time a trunk or door is opened remotely.

Smart keys also help in preventing theft of cars at gas stations or other parking spaces. This is because they send an extremely low-frequency signal that could be picked up by the proximity of a smart key, but not by other people or objects that are not within the vehicle. The signal can be detected just within 10 cm of the smart key. Thus, it is impossible to steal your vehicle just by taking the transmission.

Convenience

smart forfour key replacement keys eliminate the need to rummage through your pockets in search of keys or lock the car using remote controls. Instead, simply tap your phone's app to unlock or start the engine. Then, drive away!

As opposed to traditional key fobs that transmit a low-power signal, smart keys connect to your car via radiofrequency waves. The key fob has an encrypted chip that the antenna inside your car recognizes. If you reach the distance of your car it will open the doors and/or start the engine.

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

The automotive smart key industry is booming because of the increasing demand for safety features. These features decrease wear and tear on the ignition system of a car and ensure that the driver is the only person who can stop or restart the engine. Smart keys can also alert the driver if the battery is low and makes it more difficult for thieves to steal the vehicle.

Some systems let you open the door remotely if the battery of your smart key runs out. However, it's best to keep a spare mechanical key that is hidden in your wallet or somewhere else secure.

Autonomy

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

The goal is to stop pressing a key fob during driving so that drivers can concentrate on driving safely and secure. The technology is already available in a few luxury vehicles, and is gaining traction among major automakers trying to keep up with customer demand.

This feature is useful however, it could be risky if someone does not remove the key fob from 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 can open doors or crack the boot. It's a tactic referred to as relay attack, and it has been used by tech-savvy thieves to steal vehicles from motorists at fuel stations, and also in parking areas.

Most smart key systems do have a backup system for starting and opening the vehicle in the case of the battery being dead. The driver is required to put the dead key fob into a slot or put it near a designated part of the cockpit to trigger an emergency starting system, which typically consists of an inductive coil which transfers energy from the key to the car.

Safety

The smart key comes with an inbuilt security feature that locks the vehicle after you leave. It can also shut off the engine and open the trunk if it is discovered that you have locked the keys inside. This helps you avoid being locked from your car in an unsafe location or while you run errands.

Smart key fobs communicate with vehicles using radiofrequency signals, unlike traditional keys. It's important to remember that your car isn't monitoring you. However, because the key fob sends out these signals, it is possible for a criminal intercept these signals and control the vehicle.

Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they open the door or remotely open the trunk. This means that a cyber-savvy criminal could penetrate the system and steal your vehicle. Smart car keys, however, send out an encrypted signal that is different each time they are used. This makes them more difficult crack and more difficult to exploit by hackers.

Certain cars also allow you to start your car by walking up to it and pressing a button. These systems, in contrast to traditional ones that require you to insert and turn the keys to start the car, are powered by key fob batteries. The key fob sends the car's antenna, letting it know that you're in close proximity. The car will start the power doors and begin its engine.
