Your explanation of the problem is too vague to help you.

You claim your wife was driving the car, then how do you explain the car does not do anything when you turn the key?

Does this describe the events?:

All was normal, then she went out for a drive, then all gauges went dead (while driving), she got home and shut off the car.
You try to start the car and nothing happens.

Please describe the events in the order they happened, such that we can get a "feel" of what the problem is.

I am not familiar with your vehicle, but a detailed description of the problem may help others diagnose it.

IN MY CAR:
The gauges are controlled by a fuse in the fusebox. The fuse burns, the gauges go out. Replace the fuse. IF it blows out right away again STOP AND FIND OUT WHY.

No cranking is caused by several things: dead battery (many causes for this-starting with the voltage regulator), bad safety neutral switch, bad starter, bad ignition switch etc.... )
