I think I might have left my lights on by mistake and killed the battery, so my intelligent key won't unlock the doors. How do I gain entry to the car to release the hood in order to replace the battery?

Thanks for the advice. My brain is not functioning properly.

You're welcome. FYI the same key can open the trunk. Since it's not exposed, a lot of people don't know that the trunk has a keyhole.

Keep us updated. I feel that your headlights shouldn't kill your battery. The battery saver feature should turn them off after 5 minutes. But then if your battery is very weak, then the duration doesn't matter.
