mini keys are not working to open the car

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Yes, your key fob should have an emergency key that should open your driver's door. With such a new vehicle, my only recommendation is to reach out to your selling dealership for help! That's what they are there for, after such a recent purchase. They are in the best position to assist with all and any questions at no charge. Good luck!
