1. I had a stereo kenwood not working so i pulled the stereo, somewhere in the process the car just went dark.
2. I put the stereo back into the car the way it was prior to be pulling the stereo.
3. The fast key battery was replaced and it still does not work
4. I put the valet key and the fob together and the car will start.

so i have a working car but no fast key and no features relating to the fast key, anyone have any ideas
