The Smart Fortwo Key Fob Case Study You'll Never Forget
Smart Car Key Security Features

Smart keys communicate with your car every day, whether in your pocket or on your desk. They communicate by using radiofrequency signals.

If the smart key is within the range of the computer inside your vehicle detects the rolling code projected by the fob of the key and validates it prior getting the engine started. This can deter thieves.

Security

Many drivers are skeptical about giving 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 car key has the same security features as an ordinary fob.

Smart keys are able to lock and unlock the doors with fingerprint recognition. To make use of this feature, the driver has to put their finger on a sensor located in or near the lock button or door handle (depending on the configuration of the vehicle). This is similar to how a phone or tablet with an embedded fingerprint scanner function.

A smart key can help to protect vehicles by not transmitting the exact frequency signal repeatedly. If a fob broadcasted a signal every time it unlocked or opened a trunk remotely, it could allow thieves to connect cars to hotwires and take them away. Fortunately, this isn't an issue as smart keys emit a unique encrypted signal every time the door is opened or the trunk is opened remotely.

Smart keys also help prevent the theft of cars by thieves at fueling stations and other parking lots. Smart keys send the signal at a low frequency that can only be picked up by nearby smart keys, not by other objects or people outside the vehicle. The signal is detectable just within 10 cm of a smart key. Therefore, it is impossible to steal your vehicle by simply picking up the transmission.

Convenience


Using smart keys eliminates the need to search through your pockets in search of keys or to lock your car using remote controls. Instead, tap your phone's app to unlock or start the engine. Then, drive away!

In contrast to traditional key fobs which transmit a low-power signal smart keys communicate with your vehicle via radiofrequency waves. The key fob is equipped with an encrypted chip that the antenna in your car can recognize. Once you're within proximity to your car, it knows to unlock the doors and/or start the engine.

Some smart keys also store settings for the seats mirrors, the steering wheel and seat and allow you to change them using just one button. This feature is becoming increasingly popular and a rising number of manufacturers are adding it to their vehicles.

The market for smart keys in the automotive industry is growing rapidly due to the rising 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.

This feature is convenient, but it can also be dangerous if a driver isn't careful to remove the key fob from their pocket prior to entering or leaving the vehicle. The reason is that smart key fobs emit low-frequency signals that can be detected by a different device that could open the doors, or even pop the trunk. This is a tactic known as a relay attack and it has been used by thieves with the latest technology to steal cars from drivers at fueling stations as well as parking areas.

However, most smart key systems have a backup method for opening and starting the vehicle in the event that the battery goes out. The driver is required to put the dead key fob into a slot or hold it near a designated area of the cockpit to trigger an emergency starting system, which is usually an inductive coil that transfer energy from the key to the car.

Safety

Open Road Auto Group explains that traditional key fobs transmit the same frequency signal each time they open the door, or remotely open the trunk. smart car key repair g28carkeys.co.uk means a tech-savvy criminal could potentially gain access to the system and steal your vehicle. Smart car keys generate an encrypted code that changes every time they perform a function. This makes them more difficult to hack and harder to exploit by hackers.

Certain vehicles let you start the car by walking towards it, and pressing a button. In contrast to 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 transmits an indication to the car's radio to tell it that you are close to the vehicle, and it can then turn on its power doors and begin the engine.
