Don't Make This Mistake On Your Smart Fortwo Key Fob
Smart Car Key Security Features
Smart keys communicate with your vehicle all the time, whether in your pocket or on your desk. They communicate with each other via radiofrequency signals.
If the smart key is within range, a computer inside your vehicle detects the rolling code projected by the key fob and validates it prior beginning the engine. This helps deter thieves.
Security
Many drivers aren't keen to give control of their car to a virtual fob that is on smartphones. Security is among the major concerns. The good news is that a smart key has many of the same features that a traditional car fob does.
Smart keys, for instance, use fingerprint recognition to unlock and lock doors. To use the feature, the driver has to apply a finger to the sensor near the door handle or the lock button (depending on the car's configuration). This is similar to how a smartphone or tablet equipped with an embedded fingerprint scanner function.
Another way that a smart key keeps cars safer is by not sending the same frequency signal over and over again. If a fob transmitted the same signal each time it unlocked a door or remotely opened the trunk, it would let thieves who are adept at technology to hotwire vehicles and make them disappear. Smart keys emit a distinct signal every time a trunk or door is opened remotely.
Smart keys also stop cars from being taken away by thieves at fuel stations and other parking areas. Smart keys transmit a low frequency signal that can only be picked up by nearby smart keys, and not by other objects or people that are not within the vehicle. This signal can be detected only within 10 centimeters of the smart key. This means it is impossible to steal your vehicle just by picking up a transmission.
Convenience
Using smart keys eliminates the need to search through your pockets in search of keys or to lock the car using the remote control. You can open your car door or begin it by tapping the app on your smartphone.
In contrast to traditional key fobs that transmit a low-power signal smart keys communicate with your vehicle via radiofrequency waves. The key fob comes with an encrypted chip that the antenna in your vehicle detects. If you are within range of your vehicle, it will open the doors and begin the engine.
Some smart keys can also store settings for the steering wheel, mirrors and seat. You can then alter them by pressing a single button. This feature is becoming more popular and a growing number of manufacturers are introducing it to their automobiles.
The automotive smart key industry is growing due to the growing demand for safety features. These features reduce the wear and tear of 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 inform the driver when the battery is running low which makes it difficult for thieves to take the car.
Some systems let you open the door remotely if the battery in your smart key goes out. smart fortwo key fob to keep a backup key in your wallet or another safe location.
Autonomy
Rather than the key fob which must be in the driver's pocket to unlock or start a car, smart key systems operate when the door handle or the trunk release button is hit. These systems can also be activated when a sensor detects a driver's proximity.
The idea is to remove the necessity of pressing a key fob button while driving, allowing drivers to concentrate on driving safely and secure. The technology is present in a few premium cars and is growing in popularity with automakers that are trying to meet customer requirements.
While this feature can be useful however, it can be a risk when the driver fails to take their key fob out of the pocket prior to leaving or entering the vehicle. Smart key fobs emit low-frequency signals which can be picked by other devices that can open doors or pop the boot. It's a tactic referred to as a relay attack, and has been used by thieves who are tech-savvy to take vehicles from motorists at fueling stations and also in parking lots.
However, the majority of smart key systems come with a backup method for opening and restarting the vehicle if the battery dies. The driver typically has to place the dead key fob in an opening or keep it in a designated space in the cockpit, to trigger an emergency starting system, which is usually an inductive coil which transfers energy from the key to the vehicle.
Safety

The smart key has an integrated security feature that locks your vehicle whenever you leave. It can even shut down the engine and unlock the trunk if you have locked the keys inside. This will stop you from being locked out of your vehicle in a dangerous location or while running the errands.
Smart key fobs communicate with vehicles using radiofrequency signals, unlike traditional keys. It is important to remember that your car is not watching you. However, since the key fob broadcasts these signals, it is possible for a criminal intercept the signals and then control the vehicle.
Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they open doors or remotely pop out of the trunk. This means that a cyber-savvy criminal could possibly penetrate the system and steal your vehicle. Smart car keys emit an encrypted code that changes every time they complete an action. This makes them more difficult hack and harder to exploit by tech-savvy thieves.
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 to start the engine, these systems are powered by a key fob's battery. The key fob sends an indication to your car's antenna, letting it know that you're near. The car will activate the power doors, and start its engine.
