The newest models also allow remote management and configuration, and are cloud-based.

This code is in line with the unique serial numbers that are stored in the computer system of the car. This prevents any attempts by anyone else to start the car since only proper keys will be able to do so.

This type of technology is thought to be more secure than a conventional car key because it makes it more difficult for a thief "hot wire" the vehicle to start it.
