An immobiliser or immobilizer is an electronic device fitted to an automobile which prevents the engine from running unless the correct key (or other token) is present. This prevents the car from being "hot wired" after entry has been achieved.

Immobilisers have been mandatory in all new cars sold in Germany since 1 January 1998, in the United Kingdom since 1 October 1998, in Finland since 1998, in Australia since 2001 and in Canada since 2007. Early models used a static code in the ignition key (or key fob) which was recognised by an RFID loop around the lock barrel and checked against the vehicle's Engine Control Unit (ECU) for a match. If the code is unrecognised, the ECU will not allow fuel to flow and ignition to take place. Later models use rolling codes or advanced cryptography to defeat copying of the code from the key or ECU.

The microcircuit inside the key is activated by a small electromagnetic field which induces current to flow inside the key body, which in turn broadcasts a unique binary code which is read by the automobile's ECU. When the ECU determines that the coded key is both current and valid, the ECU activates the fuel-injection sequence.

Roberto Vecchioni (born 25 June 1943) is an Italian singer-songwriter and writer.

Vecchioni was born in Carate Brianza, province of Milan, to a family of Neapolitan origin. In 1968 he graduated in Classical Literature at the Università Cattolica of Milan, where he remained for two years as assistant lecturer of History of Religion. Later he become literature and history teacher in a Milanese High School, an activity he continues to this day.

His career in the Italian music industry began in the late 1960s as songwriter for Italian pop stars including Ornella Vanoni, Gigliola Cinquetti, Mina, Iva Zanicchi. His first solo album was Parabola of 1971. In 1973 he took part in the Sanremo Festival with "L'uomo che si gioca il cielo a dadi", continuing to release works as singer-songwriter in the following years. His 1974 LP, Il re non si diverte, obtained the Best Year's Album Award from the Italian musical critics. In 1976 he published his first commercial success, Elisir, but he gained public recognition only in the following year, with Samarcanda. With this work Vecchioni was acclaimed as one of the most skillful italian singer-songwriters: his inspiration draws mainly from autobiographical themes, intermingled with dreamy, literary and historical (often mythological) ones. His friend Angelo Branduardi played violin on the LP.
