This electronic component was invented 30 years ago and aspires to prevent the theft of your Ford Focus C-max. Indeed, thanks to a transponder and an antenna (coil) integrated in the key, and, a immobilisation control box integrated in the ECU and a reception antenna on the neiman, your Ford Focus C-max will go each time you put the key in the ignition, it controls that the code emitted by your key is in fact the one expected by your immobilization box.
