Smart Fortwo Key Fob: The Evolution Of Smart Fortwo Key Fob
Smart Car Key Security Features
Smart keys communicate with your car constantly, whether they are in your pocket or on your desk. They communicate via radiofrequency waves.
If the smart key is in reach, the computer inside your car detects and validates the rolling code projected from the key fob before beginning the engine. This helps deter thieves.
Security
Many drivers aren't comfortable handing control of their vehicle to a virtual key on a smartphone with security being among the primary concerns. The good news is that a smart car key has the same security features as traditional fobs.
For starters, smart keys make use of fingerprint recognition to unlock and lock doors. In order to use the feature, the driver must put their finger on a sensor placed in or near the door handle or the lock button (depending on the configuration of the vehicle). This is similar to the way a tablet or smartphone with an embedded fingerprint scanner works.
Another way that smart keys help keep cars safer is by not sending the same frequency signal repeatedly again. If a fob sent an alert each time it was unlocked or opened an trunk remotely, this allows thieves with a technological advantage to hotwire cars and remove them. Smart keys emit a different signal each time a trunk door is opened remotely.
Smart keys also help to stop cars from being stolen at gas stations and other parking spaces. This is because they transmit a low-frequency signal which can be detected by the proximity of a smart key, however, not by any other person or objects outside of the vehicle. This signal can only be detected within 10 cm of the smart key, meaning it is not possible for anyone to steal your car by picking up a signal from a fob that is nearby.
Convenience
Smart keys will no longer require you to dig through your pockets for a key or even lock the car using remote. You can unlock your car and start it by tapping the app on your phone.
Unlike traditional key fobs, which transmit a low-power signal smart keys connect to your vehicle via radiofrequency waves. The key fob has an encrypted chip that the antenna inside your vehicle recognizes. Once you're within distance of your car it is able to open the doors and/or start the engine.
Some smart keys also store settings for the seats or steering wheel, as well as mirrors, allowing you to set them with just one button. This feature is becoming more popular and a rising number of manufacturers are introducing it to their vehicles.
The market for automotive smart keys is booming because of the rising demand for safety features. These features lessen wear on the ignition system of a car and ensure that only the driver is able to start or stop the engine. Smart keys can also alert the driver when the battery is running low and makes it more difficult for thieves to take the car.
Certain systems let you unlock the door remotely in the event that the battery of your smart key runs out. It's best to keep a mechanical backup key in your wallet, or in a safe location.
Autonomy
Some smart key systems operate without a key-fob in the pockets of the driver. Instead, smart car key programming work by pressing the trunk release or door handle. They also operate when a sensor senses the driver is in close proximity.
The idea is to eliminate the need to use a key fob while driving, so that drivers can focus on driving safely and in a secure manner. The technology is currently available in a few luxury cars and is gaining popularity with automakers that are trying to meet customer requirements.
This feature is helpful, but it can also be risky if a driver fails to take the key fob out of their pocket prior to leaving or entering the vehicle. This is because smart key fobs emit a low-frequency signal that can be picked up by another device that can open the doors or pop the trunk. This is known as relay and has utilized by criminals with a tech-savvy to steal cars from fueling stations as well as parking spaces.
However, all smart key systems have an alternative method of opening and starting the car if the battery dies. The driver typically has to place the dead key fob into a slot or hold it near a designated area of the cockpit to trigger an emergency starting system, which typically involves an inductive coil that transmits energy from the key to the vehicle.
Safety
The smart key comes with an integrated security feature that locks your vehicle when you leave. It can also shut off the engine and unlock the trunk if it is discovered that you have left your keys inside. This will prevent you from being locked out of your car in a dangerous location or while running the errands.
Smart key fobs communicate with vehicles using radiofrequency signals, unlike traditional keys. It's important to keep in mind that your car is not tracking you. However, since the key fob broadcasts these signals, it is possible for a criminal to intercept the signals and then control the vehicle.
Open Road Auto Group explains traditional key fobs emit the same frequency signal each time they unlock doors or remotely pop out the trunk. This means that a cyber-savvy criminal could gain access to the system to take your vehicle. Smart car keys, however, put out an encrypted signal each time they are used. This makes them more difficult to hack, and also more difficult for thieves who are tech-savvy to take advantage of.
Some vehicles allow you to start the vehicle by walking up to it, and pressing the button. These systems, in contrast to traditional models that require you insert and turn the keys and are powered by key fob batteries. The key fob sends an alert to your car's antenna, letting it know that you're close. The vehicle will then start the power doors and begin its engine.
