How your immobiliser system functions on Hyundai Ioniq

Before detailing the different alternatives available to you, here is a short introduction to show you the purpose and functions of the immobilizer in your Hyundai Ioniq. This electronic part came out 30 years ago and intends to prevent the theft of your Hyundai Ioniq. 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 Hyundai Ioniq will go each time you put the key in the ignition, it checks that the code emitted by your key is actually the one asked by your immobilization box. It is only at this instant, that it will enable you to turn on your car. It is thanks to RFID technology (chip in the key) that this unit will work.
