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 Opel Antara will go each time you place the key in the ignition, it controls that the code emitted by your key is actually the one expected by your immobilization box.

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, replicate the procedure until you have entered the entire code.
