11 "Faux Pas" You're Actually Able To Do With Your 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 with each other by using radiofrequency signals.

When the smart key is in distance, the computer in your car is able to recognize and verify the rolling code projected from the key fob before getting the car started. This helps to deter thieves.

Security

Many drivers aren't comfortable the transfer of control of their vehicle to a digital key that is stored on a smartphone, with security being among the most important concerns. smart car key case is a smart key can provide many of the same features that a traditional car fob does.

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

Another way that a smart key keeps cars secure is by not sending the same frequency signal repeatedly again. If a fob sent an alert each time it opened or locked the trunk remotely, this could allow thieves to wire cars to eliminate them. Thankfully, this is not an issue because smart keys emit a unique encrypted signal every time doors are opened or the trunk is remotely opened.

Smart keys also prevent cars from being stolen by thieves at fuel stations as well as other parking spots. Smart keys transmit an extremely low-frequency signal that can only be detected by nearby smart keys, not by any other objects that are not within the vehicle. The signal is detectable just within 10 cm of the smart key. This means it is impossible to steal your vehicle just by picking up an engine.

Convenience

Smart keys eliminate the need to fumble through your pockets to find keys or to secure your car using the remote control. You can unlock your car or start it by tapping on the app on your phone.

Contrary 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 in your car can recognize. If you're within proximity to your vehicle, it will open the doors and start the engine.

Some smart keys also save settings for the seat mirrors, the steering wheel and seat, allowing you to set them with just one button. This feature is becoming more popular and a rising number of companies are adding it to their automobiles.

The industry of automotive smart keys is growing due to the increasing demand for security features. These features reduce the wear and tear of the ignition system of a vehicle and ensure that the driver is the sole person who can stop or start the engine. Smart keys can also alert the driver when the battery is in low and make it more difficult for thieves to take the car.

Certain systems also allow you to open your door from a distance in the event that the battery of your smart key dies. However, it's advisable to have a spare mechanical key in your wallet or other safe.

Autonomy

Instead of an actual key fob that needs to be carried in the pocket of the driver to unlock or start a car, some smart key systems work when the car door handle or the trunk release button is hit. These systems also work when a sensor detects that the driver is near.

The idea is to remove the necessity of pressing the key fob while driving, so drivers can concentrate on driving safely and secure. The technology is already available in some premium cars, and is becoming popular with mainstream automakers who are trying to meet customer needs.

This feature is helpful, but it can also be risky if someone forgets to take the key fob out of their pocket before entering or leaving the vehicle. Smart key fobs emit low-frequency signals which can be picked by other devices that open doors or crack the boot. It's a tactic referred to as relay attack, and it's been used by thieves who are tech-savvy to take vehicles from motorists at fueling stations as well as parking garages.

However, most smart key systems come with an alternate method of 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 close to a special space in the cockpit to activate the emergency starting system. This typically involves an inductive coil that transfers energy from the key to the vehicle.

Safety

The smart key has a built-in feature of security that locks your vehicle after you leave. The smart key can close the vehicle and unlock the trunk even if the keys are still in the trunk. This will prevent you from being locked out of your car in a dangerous area or while you run the errands.

Smart key fobs can communicate with vehicles through radiofrequency signals, in contrast to conventional keys. While it's important to keep in mind that your vehicle isn't spying, the fact that the key fob sends these signals makes it possible for 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 unlock the door or remotely open out the trunk. This implies that a hacker can potentially penetrate the system to take your vehicle. Smart car keys, however, send out an encrypted signal every time they perform this function. This makes them harder to crack, and even more difficult for thieves who know how to exploit.

Certain cars allow you to start the vehicle by walking 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 sends a signal to your car's antenna, letting it know that you're in close proximity. The car will start the power doors and start its engine.
