Match the symptom to the service
A flat with a usable spare points to a tire change. Clicking or silence when you turn the key may mean a jump start is worth asking about. An empty tank calls for fuel delivery, and keys visible through the window call for lockout service.
Hybrids and electric vehicles have their own versions of these problems. See hybrid battery service, EV 12V battery service, and EV tire change if that describes your vehicle.
