12 Companies That Are Leading The Way In Smart Fortwo Key Fob

Smart Car Key Security Features

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

If the smart key is in the range of the computer inside your vehicle is able to recognize the rolling code projected by the key fob and validates it prior to starting the engine. This helps thwart thieves.

Security

Many drivers are wary of handing over control of their vehicle to a virtual key on a smartphone, with security being among the most important concerns. The good news is that a smart car spare key car key has all of the security features as an ordinary fob.

For starters, smart keys utilize fingerprint recognition to unlock and lock doors. To use the feature, a person must place their finger on a sensor close to the lock button or door handle (depending on the vehicle's configuration). This is similar to how a tablet or smartphone that has a fingerprint scanner integrated works.

Another way that smart keys keep cars secure is by not sending the same frequency signal repeatedly again. If a fob broadcasted the same signal every time it opened the door remotely or opened the trunk, it would allow thieves who are tech-savvy to use hotwires to remove them. Thankfully, this is not a problem because smart keys emit a unique encrypted signal each when doors are opened or the trunk is remotely opened.

Smart keys also can help in preventing theft of cars at gas stations and other parking spaces. This is because they send an extremely low-frequency signal that could be detected by a nearby smart key, but not by other people or objects outside of the vehicle. The signal can only be identified within 10 cm of the smart key, which means it is virtually impossible for anyone to steal your car just by picking up a transmission from a fob that is nearby.

Convenience

Smart keys eliminate the need to rummage through your pockets for keys or lock the car with a remote control. Instead, tap your smartphone in the app to unlock or start the engine and go on your way!

Smart keys, unlike traditional key fobs that transmit a low power signal, communicate with your car smart key via radiofrequency waves. The key fob contains an encrypted chip that the antenna inside your car can recognize. If you are within range of your vehicle, it will unlock the doors and begin the engine.

Some smart keys can also save settings for the seats, mirrors and steering wheel, allowing you to set them with a single click. This feature is becoming increasingly popular and a growing number of companies are adding it to their vehicles.

The automotive smart key market is growing because of the increasing demand for safety and security features. These features minimize wear and tear on a car's ignition system and ensure that the driver is the sole person who can stop or start the engine. Smart keys can also alert the driver if the battery is in low and make it more difficult for thieves to take the car.

Certain systems allow you to open the door from a distance if your smart key battery runs out. However, it's best to keep a spare mechanical key that is hidden in your wallet or in a safe place.

Autonomy

Instead of the key fob which must be carried by the driver to open or start a car, some smart key systems function when the door handle or the button for trunk release is pressed. These systems also work when a sensor senses the driver is near.

The idea is to eliminate the necessity of pressing a key fob button while driving, allowing drivers to concentrate on driving safely and securely. The technology is already available in a few luxury vehicles, and it's gaining popularity among major automakers trying to keep up with customer demand.

This feature is convenient however it can be risky if a driver fails to remove the key fob from their pockets prior to leaving or entering the vehicle. That's because smart key fobs emit an ultra-low-frequency signal that could be picked up by another device that could open the doors, or even pop the trunk. This is a technique called a relay, and it's used by hackers to steal cars at fuel stations and parking spaces.

However, all smart key systems have an alternate method of opening and re-starting the vehicle in the event that the battery goes out. The driver usually must put the dead key fob into an opening or keep it near a special part of the cockpit to trigger an emergency start system, which typically consists of an inductive coil that transmits energy from the key to the vehicle.

Safety

The smart key has an inbuilt security feature that locks the vehicle after you leave. The smart key will shut down the vehicle and unlock the trunk if the keys are still inside. This prevents you from being locked out of your car in an unsafe location or while completing on errands.

Smart key fobs communicate with vehicles using radiofrequency signals, unlike traditional keys. While it's important to remember that your vehicle isn't spying on your, the fact that the key fob transmits these signals allows criminals to steal them and gain control of the vehicle.

Open Road Auto Group explains that traditional key fobs transmit the same frequency signal each time they open the door or remotely pop the trunk. This means that a criminal with a technologically advanced mind could possibly infiltrate the system and steal your vehicle. Smart car keys emit a different encrypted code each time they carry out some function. This makes them difficult to crack and more difficult to exploit by hackers.

Certain cars also allow you to start your car by simply walking to it and pressing the button. These systems, unlike traditional models that require you to insert and turn the keys and are powered by key fob batteries. The key fob sends a signal to your car's antenna, letting it know that you're within. The vehicle will then activate the power doors, and begin its engine.
