How your immobiliser system works on Chevrolet Sonic
Before explaining the different solutions available to you, here is a short introduction to explain the intent and operation of the immobilizer in your Chevrolet Sonic. This electronic element came out 30 years ago and intends to prevent the theft of your Chevrolet Sonic. 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 Chevrolet Sonic will go each time you insert the key in the ignition, it checks that the code emitted by your key is indeed the one asked by your immobilization box. It is only at this instant, that it will allow you to start. It is thanks to RFID technology (chip in the key) that this unit will work.
The different alternatives to bypass the immobiliser on your Chevrolet Sonic
Enter the code to turn off the immobiliser
First methodology, your key no longer enables your Chevrolet Sonic to start, you want to disable the immobiliser of your Chevrolet Sonic, but first of all you should try this technique to start it and take it to a mechanic check that you can not perform a less significant process to bring back the normal start of your car. Indeed, with your car you should have a spare key (which you should try and which should start your Chevrolet Sonic), 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 car 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 process until you have entered the whole code. This should enable you to start your Chevrolet Sonic without having to remove the immobiliser.
Fix your key at a key specialist or your car dealership

Manually remove your immobilizer
Although you may be tempted to bypass the immobilizer from your Chevrolet Sonic, this is not recommended at all for several reasons. First your Chevrolet Sonic would be much more vulnerable to theft attempts. Indeed, without an immobiliser box, simply doing “the wires” may be enough to start it.
