Smart Car Key Security Features

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

When the smart key is within the range of the computer inside your vehicle is able to recognize the rolling code projected by the fob of the key and confirms it prior to beginning the engine. This helps deter thieves.

Security

Many drivers are hesitant about handing over control of their vehicle to a digital key on a smartphone, with security being among the main concerns. The good news is that smart car keys have many of the same security features as the traditional fob.

For starters, smart keys use fingerprint recognition to lock and unlock doors. To use the feature, the driver has to place their finger on the sensor near the door handle or the lock button (depending on the car's configuration). This is similar to how a phone or tablet with an embedded fingerprint scanner works.

A smart key could also help protect cars by not sending the exact same frequency signal repeatedly. If a fob transmitted the same signal every time it locked doors or remotely opened the trunk, this would allow tech-savvy thieves to use hotwires to make them disappear. Smart keys emit a unique signal each time a trunk or door is opened remotely.

Smart keys can also to stop cars from being stolen at gas stations and other parking areas. Smart Roadster Key Programming keys emit a low frequency signal that can only be detected by nearby smart keys, not by other objects or people that are not within the vehicle smart key. The signal can be identified within 10 cm of the smart key, meaning it is virtually impossible for someone to steal your car by stealing a transmission from a fob that is nearby.

Convenience

Smart keys will no longer require you to search your pockets for keys or even lock the car using a remote. You can unlock your car or start it by tapping on the app on your phone.

Smart keys, in contrast to traditional key fobs that emit an extremely low power signal, communicate with your car through radiofrequency waves. The key fob is equipped with an encrypted chip which the antenna inside your vehicle detects. If you reach the of the car's range it will unlock the doors and/or start the engine.

Certain smart keys also store settings for the steering wheel, mirrors and the seat. You can 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 market for automotive smart keys is growing because of the increasing demand for security and safety features. These features help reduce the wear and tear on the ignition system of a car, and also ensure that only the owner can start or stop the engine. Smart keys also notify the driver when the battery is running low which makes it difficult for thieves to steal the car.

Certain systems also allow you to open your door from a distance when the battery in your smart key goes out. But, it's better to have a spare mechanical key that is hidden in your wallet or else secure.

Autonomy

Some smart key systems operate without a key fob that is in the driver's pockets. Instead, they function by pressing the trunk release or car door handle. These systems can be activated when a sensor detects a driver's proximity.

The idea is to make it unnecessary to press a key fob when driving, allowing drivers to concentrate on driving safely and secure. The technology is already present in some luxury vehicles and it's growing in popularity with mainstream automakers trying to keep up with the customer demand.

This feature is helpful, but it can also be dangerous if a driver forgets to remove the key fob from their pocket prior to leaving or entering the vehicle. Smart key fobs emit low-frequency signals which can be detected by other devices that can open doors or pop the boot. This is a technique known as relay and has been used by cyber-savvy criminals to steal cars at fueling stations as well as parking spaces.

However, all smart key systems have a backup method for opening and starting the vehicle if the battery dies. The driver usually must put the dead key fob in a slot or hold it in a specific space in the cockpit, to trigger an emergency start system, which typically consists of an inductive coil which transfers energy from the key to the vehicle.

Safety

The smart key comes with an inbuilt security feature that will lock your vehicle when you leave. The smart key will stop the vehicle from being operated and unlock the trunk even if the keys are still inside. This will keep you from being locked out of your vehicle in a dangerous location or when running the errands.

Contrary to conventional keys smart key fob can communicate with the vehicle using radiofrequency signals. While it's important to keep in mind that your vehicle isn't spying on your, the fact that the key fob transmits these signals allows criminals to intercept them and gain control over the vehicle.

Open Road Auto Group explains that traditional key fobs send out the same frequency signal every time they unlock the door, or remotely open the trunk. This means that a hacker could possibly penetrate the system and take your vehicle. Smart car keys, however, send out a different encrypted signal each time they use this function. This makes them more difficult to crack, and more difficult for thieves with a technological edge to gain access to.

Certain vehicles allow you to start the car by walking right up to it, and 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 your car's antenna, letting it know that you're close. The vehicle will then activate the power doors, and begin its engine.
