If you need to perform an anti-theft reset on your Chevrolet Sonic, there are a few options available. One simple method involves disconnecting the negative battery terminal for 15 to 30 minutes, then reconnecting it before trying to start the car. This could resolve the issue and reset the system in some cases, but in others, the problem may persist, requiring further steps. One option is to try using a spare key, as a damaged key may not be recognized by the anti-theft system. If the key is in good condition or you don't have a spare, you can also try placing the key in the run position and waiting for about ten minutes. If these steps do not rectify the issue, it may be necessary to have your Sonic professionally serviced.
