Does anyone know where I can purchase a mechanical metal key that goes inside the key fob? My local karma dealership in Pasadena says they don’t carry keys for the Karma. I tried eBay and Amazon but no luck. I only have one key fob and the mechanical Metal Key was missing when I bought the car. I’m worried if the 12V battery should ever die, I won't be able to get inside the car to open up the hood without smashing a window!
