Smart Car Key Security Features

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

Fortunately, this isn't an issue since smart keys emit an encrypted signal every when the door is opened or the trunk is remotely opened.

Smart keys also help prevent vehicles from being taken by thieves at fuel stations and other parking areas. Smart keys transmit the signal at a low frequency that can only be picked up by nearby smart keys, not by people or other objects outside the vehicle.
