This electronic element came out 30 years ago and aspires to prevent the theft of your Renault Megane. 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 Renault Megane will go each time you insert the key in the ignition, it checks that the code emitted by your key is indeed the one expected by your immobilization box.

Indeed, with your vehicle you should have a spare key (which you should try and which should start your Renault Megane), but if you don’t have it you should at least have the “code card”, it contains the start code. Thanks to this code, you will still be able to start your vehicle by entering it manually. To do this, turn on the ignition, use your centralized button to enter the digits, several quick presses (example: 2 for digit 2) then a stop of one and a half seconds to validate the digit and resume, repeat the operation until you have entered the entire code.
