Vehicle Smart Key Technology The smart key technology found in automobiles allows drivers to open and start their vehicle by simply pressing the door handle or placing the key into the pocket. It also permits various other adjustments, including the position of the seat as well as internal temperature settings and mirror positioning. However, this could also lead to security concerns. Security Smart keys are key fobs that are computerized that communicate with the vehicle through an embedded antenna to unlock doors and begin the motor. Smart key fobs, as opposed to traditional keys that emit the same frequency every time they're used, transmit encrypted signals that are compatible with the specific car to which they belong to. This makes it much more difficult for hackers with the latest technology to detect or spoof the signal, and use your key to steal your car.

The Smart Key automatically unlocks and opens the doors and the tailgate when it is within 1.5 meters. It also allows you to start the engine by pressing a button on its key. Certain smart keys, like those from BMW, also have user-specific settings that allow drivers to alter the seat, mirrors and the steering wheel's position and audio preferences at the press of a single button. They also come with the backup lock, which stops the vehicle from starting without the key. This technology can prevent drivers from locking their vehicles, particularly when fumbling in a purse or backpack to locate keys in a parking area packed with people or on an area with high rates of crime. Many systems also notify drivers when keys are in danger of being depleted, though this feature differs by manufacturer.
