This lock has a sensor attached to an alcohol meter. Before starting the engine, the driver must blow into this machine. If the result is ' negative ' or the alcohol level is at the allowable level, the car will start after turning on the key. In contrast, the driver must wait through the drunk can start the machine.

In addition, Volvo also offers an automatic (programmed) key. This key will automatically shutdown if the car is over speed.
