Smart Car Key Security Features Smart keys communicate with your vehicle constantly whether they are in your pocket or on your desk They communicate with one another using radiofrequency waves If the smart key is within range a computer within your car recognizes the rolling code projected by the key fob and confirms it prior to beginning the engine This helps to deter thieves Security Many drivers are hesitant about giving control of their vehicle to a virtual key on a smartphone with security being one of the most pressing concerns The good news is that smart car keys have all of the security features as the traditional fob Smart keys are able to lock and unlock the doors through fingerprint recognition To utilize the feature a person must place their finger on the sensor near or inside 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 works Another way that smart keys keep cars secure is by not sending the same frequency signal repeatedly again If a fob broadcasted the same signal every time it unlocked doors or remotely opened the trunk it could permit thieves with a techsavvy mindset to hotwire vehicles and drive them away Smart keys emit a different signal each time a trunk or door is opened remotely Smart keys can also help in preventing theft of cars at gas stations and other parking spots They transmit the signal at a low frequency that can be picked up by a nearby smart key however not by any other person or objects that are not within the vehicle The signal can only be detected within 10 centimeters of the smart key meaning it is not possible for anyone to steal your car just by stealing a transmission from a nearby fob Convenience Smart keys eliminate the need to dig through your pockets to locate the key or secure your car using the remote control You can unlock your car and start it by tapping on the app on your smartphone Smart keys

be kept in the pocket of the driver to unlock or start a car smart key systems operate when the car door handle or the trunk release button is pressed These systems can also be activated when a sensor detects the drivers proximity The idea is to stop pressing a key fob when driving so that drivers can focus on driving safely and securely The technology is present in certain luxury vehicles and is gaining popularity with major automakers who are working to meet consumer requirements Although this feature is convenient but it could be risky in the event that the driver does not take their key fob out of the pocket prior to entering or exiting the vehicle Thats because smart key fobs emit lowfrequency signals that can be picked up by another device that can open the doors or even pop the trunk This is a tactic known as a relay attack and it has been used by thieves who are techsavvy to take cars from drivers at fueling stations and even in parking spaces Most smart key systems do come with a backup method to open and start the vehicle in the case of an insufficient battery The driver typically has to place the dead key fob in a slot or put it near a special space in the cockpit to trigger an emergency start system which usually involves an inductive coil that transfers energy from the key to the vehicle Safety The smart key has an inbuilt security feature that locks your vehicle after you leave It will even shut down the engine and unlock the trunk if you have left your keys inside This helps you avoid being locked out of your car an area where it is unsafe or when

towards it and pressing a button These systems unlike conventional models that require you insert and turn the keys are powered by key fob batteries The key fob will send a signal to the cars antenna notify it that youre close to the vehicle and it can then activate its power doors and start the engine
