You just push on the gas cap door. There is no remote release.
On a 2008 Chrysler 300, the gas cap release button is located on the driver's side, near the floor, to the left of the driver's seat. It is typically a small lever or button that you need to pull or press to unlock the gas cap door. If you don't see a button, the gas cap door may just need to be pushed to open, as some models have a spring-loaded mechanism. Always check the owner's manual for specific instructions if you're having trouble.
