Abstract
An alco key for a car uses the immobiliser associated with the car's ignition system. A key is used for remote control of the immobiliser of a car, said key comprising an analysis device for determining the alcohol level of a person and, arranged to transmit a signal authorizing starting the car only if the alcohol level is below a predetermined limit. The method comprises the steps of--transmitting an open signal to at least one door of the car--operating the ignition key to start the car,--detecting the alcohol level of a person and, if the level is below a predetermined limit level, transmitting an ok signal wirelessly to signal that it is ok to start the car,--starting the car only if said ok signal has been received by the immobiliser. The opening of doors can be controlled in a similar way.
