If all keys are lost, the car needs to be hauled to an Audi dealership or a locksmith professional with VAG-specific (Volkswagen AG) diagnostic tools.

Just extremely specific older designs (like some 2000s-era A8s) had rechargeable keys. Almost all modern Audi fobs utilize non reusable lithium batteries and do not charge while the car is running.
5. Why is the traffic signal on my key fob flashing?
A flashing red light typically indicates that the key is transferring a signal. If it flashes quickly or turns a different color (on some models), it might be a caution that the internal battery is reaching a critical low-voltage state.
