5. Smart Keys and Proximity Fobs
The most modern iteration, these do not require a physical key to be placed into the ignition. As long as the fob is inside the vehicle, the motorist can begin the car with a "Push to Start" button.

Modern car security involves a handshake in between the key and the car's computer system. During shows, a professional links a device to the lorry's OBD-II port. The software application "introduces" the brand-new key's distinct ID to the car. In many cases, the professional needs to likewise "wipe" the old keys from the system so that if the lost secrets are found by a complete stranger, they can no longer begin the vehicle.
