Why We Love Smart Fortwo Key Fob (And You Should Also!)
Smart Car Key Security Features
Smart keys communicate with your car all the time, whether in your pocket or on your desk. They communicate using radiofrequency waves.
When the smart key is within range, a computer in your car recognizes the rolling code projected by the fob of the key and validates it prior to beginning the engine. This helps deter thieves.
Security
Many drivers are hesitant to hand over control of their car to a virtual fob via a smartphone. Security is among the most important concerns. The good news is a smart key comes with many of the same features as a traditional car fob.
For starters, smart keys utilize fingerprint recognition to lock and unlock doors. To make use of this feature, the driver has to put their finger on a sensor located close to the door knob or lock handle (depending on the vehicle's configuration). This is similar to how a tablet or smartphone that has the fingerprint scanner inside works.
A smart key could also ensure the safety of vehicles by not transmitting the exact frequency signal repeatedly. If a smart key sends a signal every time it opened or locked an trunk remotely, this allows thieves with a technological advantage to connect cars to hotwires and take them away. Thankfully, this is not an issue since smart keys emit a distinct encrypted signal each when doors are opened or the trunk is remotely opened.
Smart keys also help prevent the theft of cars by thieves at fuel stations and other parking areas. This is because they transmit an extremely low-frequency signal that could be detected by the proximity of a smart key, but not by other people or objects that are not within the vehicle. The signal is only detected within 10 centimeters of the smart key, meaning it is difficult for someone to steal your car just by stealing a transmission from a nearby fob.
Convenience
Smart keys eliminate the need to rummage through your pockets for a key or to lock your car with remote. Instead, just tap on your smartphone in the app to unlock or start the engine and drive away!
Unlike traditional key fobs, that transmit a low-power signal, smart keys connect to your vehicle through radiofrequency waves. The key fob contains an encrypted chip which the antenna inside your vehicle detects. If you're within distance of your vehicle, it will open the doors or start the engine.
Some smart keys can also save settings for the steering wheel, mirrors and the seat. 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 smart keys in the automotive industry is booming due to increasing demand for security and safety features. These features help reduce the wear and tear on the ignition system of a car and ensure that the driver is the sole person who can stop or restart the engine. Additionally, smart keys can alert the driver when the battery is depleted and make it more difficult for thieves to take the vehicle.
Certain systems allow you to open the door from a distance if the battery of your smart key runs out. It's best to keep a mechanical backup key in your wallet or other secure location.
Autonomy
Some smart key systems operate without a key-fob in the pockets of drivers. Instead, they operate by pressing the trunk release or car door handle. These systems can also be activated if a sensor detects the driver's proximity.
The idea is to avoid pressing a key fob during driving, allowing drivers to focus on driving safely and securely. key for smart car is currently available in a few luxury cars and is becoming popular with major automakers who are trying to meet customer needs.
While this feature can be useful but it could be risky if the driver forgets to take their key fob from the pocket before going into or out of the car. This is because smart key fobs emit a low-frequency signal that can be detected by a different device that could open the doors or even the trunk. This is known as a relay, and it's been used by cyber-savvy criminals to steal cars from fueling stations as well as parking lots.
However, many smart key systems include an alternative method of opening and starting the vehicle when the battery is dead. The driver should usually insert the dead key in a slot, or hold it close to a special area in the cockpit to activate the emergency starting system. This typically involves an inductive coil that transfers energy from key to car.
Safety
The smart key comes with a built-in security feature that locks the vehicle once you leave. The smart key will close the vehicle and unlock the trunk the keys remain inside. This will stop you from being locked out of your car in an unsafe location or when running errands.
In contrast to conventional keys, a smart key fob communicates with vehicle via radiofrequency signals. While it's vital to keep in mind that your vehicle isn't spying on your however, the fact that the key fob sends these signals allows criminals to steal them and gain control over the vehicle.
Open Road Auto Group explains traditional key fobs emit the same frequency signal every time they unlock a door or remotely pop out the trunk. This means that a cyber-savvy criminal could infiltrate the system and take your vehicle. Smart car keys emit an encrypted code that changes each time they carry out an action. This makes them more difficult to crack and more difficult to be exploited by thieves with a technological edge.
Certain vehicles let you start the car by walking towards it and pressing the button. Contrary to traditional models which require you to insert and turn the key and then turn it on, these systems are powered by a key fob battery. The key fob will send an signal to the car's radio to inform it that you are close to the vehicle, and it can then turn on its power doors and start the engine.
