Smart Fortwo Key Fob: A Simple Definition
Smart Car Key Security Features

Smart keys communicate with your vehicle all the time, whether in your pocket or on your desk. They talk to each other using radiofrequency waves.

If the smart key is in reach, the computer inside your car detects and validates the rolling code projected from the fob of your key before starting the vehicle. This helps deter thieves.

Security

Many drivers aren't comfortable giving control of their vehicle to a virtual key on a smartphone, with security being among the most pressing concerns. The good news is that the smart car key comes with all of the security features as the traditional fob.

Smart keys unlock and lock the doors with fingerprint recognition. To access the feature, the driver needs to place a finger on the sensor located in or near the door handle or the lock button (depending on the vehicle's configuration). This is similar to how a phone or tablet equipped with an embedded fingerprint scanner operates.

Another way that a smart key keeps vehicles safe is by not sending the same frequency signal repeatedly again. If a fob sent an individual signal each time it was unlocked or opened the trunk remotely, this would enable tech-savvy thieves wire cars to take them away. Thankfully, this is not a problem because smart keys emit a unique encrypted signal every time doors are opened or the trunk is remotely opened.

Smart keys also can help protect cars from theft at gas stations or other parking spaces. This is because they send an extremely low-frequency signal that could be picked up by an adjacent smart key but not by people or objects outside of the vehicle. The signal can be detected at a distance of 10 cm from a smart key. Therefore, it is impossible to steal your vehicle by simply taking an engine.

Convenience

Smart keys eliminate the need to search your pockets for keys or even lock the car using a remote. Instead, tap your phone 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 they communicate with your car via radiofrequency signals. The key fob contains an encrypted chip that the antenna inside your car recognizes. If you're within distance of your vehicle, it will unlock the doors or begin the engine.

Some smart keys can also save settings for the steering wheel, mirrors and seats. You can set them by pressing a single button. This feature is becoming more popular and a rising number of manufacturers are incorporating it to their vehicles.

The market for car smart keys is growing because of the increasing demand for security and safety features. These features lessen the wear and tear on the ignition system of a car, and also ensure that only the driver has the ability to start or stop the engine. smart car key programmer can also inform the driver if the battery is not fully charged which makes it difficult for thieves to take the car.

Some systems let you open the door from a distance if your smart key battery runs out. It is best to keep a spare mechanical key in your wallet or a safe place.

Autonomy

Rather than a key fob that must be carried by the driver to open or start a car, smart key systems operate when the door handle or the button for trunk release is pressed. These systems can also be activated when a sensor detects that a driver is near.


The goal is to stop pressing a key fob while driving, so that drivers can focus on driving safely and in a secure manner. The technology is already available in a few luxury cars and is gaining popularity with mainstream automakers who are trying to meet customer demands.

While this feature can be useful however, it can be a risk in the event that the driver does not take their key fob out of the pocket before entering or exiting the vehicle. That's because smart key fobs emit low-frequency signals that can be detected by a different device that could open the doors or pop the trunk. This is a tactic known as relay attack, and it's been used by thieves with a technological advantage to take vehicles from motorists at fueling stations, and even in parking areas.

However, the majority of smart key systems come with a backup method for opening and restarting the vehicle if the battery dies. The driver must usually place the dead key fob inside an opening, or keep it close to a special space in the cockpit to start the emergency starter. This usually involves an inductive coil that transmits energy from the key to the vehicle.

Safety

The smart key comes with an inbuilt security feature that locks your vehicle when you leave. The smart key can stop the vehicle from being operated and unlock the trunk even when the keys are inside. This prevents you from getting locked from your car in an area where it is unsafe or while completing errands.

Smart key fobs communicate with vehicles using radiofrequency signals, in contrast to conventional keys. It's important to keep in mind that your car is not watching you. However, since the key fob sends out these signals, it's possible for a criminal intercept the signals and then control the vehicle.

Open Road Auto Group explains that traditional key fobs transmit the same frequency signal every time they unlock the door or remotely pop the trunk. This implies that a hacker could infiltrate the system and steal your vehicle. Smart car keys generate an encrypted code that is different each time they carry out an action. This makes them harder to crack, and even more difficult for thieves with a technological edge to make use of.

Some vehicles allow you to start the car 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 battery. The key fob transmits an alert to your car's antenna, letting it know that you're within. The car will open the power doors and begin its engine.
