12 Companies That Are Leading The Way In 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 using radiofrequency waves.
When the smart key is in the range of the computer inside your vehicle detects the rolling code projected by the fob of the key and validates it prior to getting the engine started. This helps to deter thieves.
Security
Many drivers are hesitant about the transfer of control of their vehicle to a virtual key on a smartphone with security being one of the most important concerns. The good news is that a smart key comes with many of the same features as a traditional car fob.
Smart keys unlock and lock the doors through fingerprint recognition. To use the feature, the driver needs to place their finger on the sensor located 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 a fingerprint scanner integrated functions.
Smart keys can also make cars safer by not sending the exact frequency signal repeatedly. If a key sent a signal every time it opened or locked an trunk remotely, this would enable tech-savvy thieves connect cars to hotwires and eliminate them. Smart keys emit a distinct signal every time a trunk or door is opened remotely.
Smart keys also protect cars from being taken away by thieves at fueling stations and other parking areas. This is because they transmit an extremely low-frequency signal that could be detected by a nearby smart key, but not by other people or objects that are not within the vehicle. The signal can only be detected within 10 centimeters of the smart key, meaning it is difficult for anyone to steal your car just by stealing a transmission from a nearby fob.
Convenience
Using smart keys eliminates the need to rummage through your pockets to locate the key or lock the car using the remote control. Instead, simply tap your phone's app to unlock or start the engine and drive away!
As opposed to G28CarKeys which transmit a low-power signal, smart keys communicate with your car via radiofrequency waves. The key fob comes with an encrypted chip that the antenna in your car recognizes. When you get within proximity to your car it is able to open the doors and/or start the engine.
Certain smart keys also save settings for the steering wheel, mirrors and the seat. Then, you can change them by pressing a single button. This feature is becoming increasingly popular, and a greater amount of manufacturers are adding this feature to their vehicles.
The market for automotive smart keys is booming because of the increasing demand for safety features. These features decrease wear on the ignition system of a car, and also ensure that only the driver is able to start or stop the engine. Furthermore, smart keys also notify the driver if the battery is depleted and makes it more difficult for thieves to steal the vehicle.
Certain systems allow you to open the door remotely if the battery of your smart key runs out. It's best to keep a backup mechanical key in your wallet or another safe place.
Autonomy
Instead of an actual key fob that needs to be in the driver's pocket to unlock or start a car, some smart key systems work when the door handle or the trunk release button is pressed. These systems can also be activated when an sensor detects a driver's proximity.
The idea is to avoid pressing a key fob during driving so that drivers can focus on driving safely and secure. The technology is available in some luxury vehicles and is gaining traction among mainstream automakers trying to keep up with the customer demand.
While this feature can be useful however, it can also be dangerous if the driver forgets to take their key fob from the pocket prior to getting into or out of the vehicle. This is because smart key fobs emit low-frequency signals that can be detected by a device that could open the doors or even the trunk. It's a tactic called a relay attack and it's been employed by thieves who are tech-savvy to take cars from drivers at fuel stations, and even in parking lots.
However, many smart key systems come with an alternative method of opening and starting the vehicle if the battery dies. The driver is required to put the dead key fob into a slot or put it near a special area 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 comes with a built-in security feature that locks the vehicle once you leave. The smart key can stop the vehicle from being operated and unlock the trunk even when the keys are in the trunk. This will keep you from being locked out of your car in a hazardous location or while you run errands.
Contrary to conventional keys smart key fob connects to the vehicle using radiofrequency signals. It's important to keep in mind that your car isn't watching you. However, since the key fob sends out these signals, it's possible for a criminal to intercept the signals and then control the vehicle.
Open Road Auto Group explains that traditional key fobs emit the same frequency signal each time they unlock the door or remotely pop the trunk. This means that a cyber-savvy criminal could potentially hack into the system and take your vehicle. Smart car keys generate a different encrypted code every time they complete the task. This makes them much more difficult to break, and makes them more difficult for tech-savvy thieves to make use of.
Certain cars allow you to start the car by walking up to it, pressing the button. These systems, unlike traditional ones that require you to insert and turn the keys to start the car, are powered by key fob batteries. The key fob sends the car's antenna, letting it know that you're within. The car will activate the power doors, and begin its engine.
