Car Fails to start with key or push button on 2006 Audi A6

Car won't start, no click or anything. Lights, radio, locking/unlocking, instrument panel, and windows all work when key is on. Battery checked and has full power. Tried both sets of keys. Seems like the key is not recognized in the car's computer or maybe the car thinks that the car is not in park. Any way to fix via a reset switch hidden somewhere?
