This electronic component was invented 30 years ago and aims to prevent the theft of your Ford F 250. Indeed, thanks to a transponder and an antenna (coil) included in the key, and, a immobilisation control box included in the ECU and a reception antenna on the neiman, your Ford F 250 will go each time you put the key in the ignition, it controls that the code emitted by your key is indeed the one asked by your immobilization box.
