Were going to need more information. When you try to turn it over, wht is it doing? Is it a crank no start? No crank? Lights on the dash on?

Check to see if the starter is getting 12 volts to the solenoid to power up the starter. No 12 volts is the reason why the engine is not cranking over.

Ok. If I don't find 12v, what could be the issue then? I know if I find 12v then I need to replace the starter. The car is at my father in law garage which is about 1.5 hours away so I need to have a well thought out plan when I get there.

If you dont have 12v at the starter, then you will need to check the ignition switch. See if the switch is allowing power to come through to the starter.
The other thing I would do is try another key. If the battery is dead in the key, the EWS system will not recognize the key and will not start. But i am not sure what the parameters are. Meaning will the car just turn on but not crank, or just crank all day long no start.

You can also check out the relay to the starter. Kill 2 birds with one stone. You can do a swap if you think its the relay after testing. Just keep it simple.
I would start at the ignition switch and work your way down to the starter. It should only take you a few minutes to diagnose the line. The only anomaly would be the EWS system, but again you could test the EWS and see if it is triggering the 5v signal.

You can attach a wire to the starter solenoid and touch the other end to the positive jump port in the engine compartment. That will provide the 12 volt power needed to energize the starter.
I had an Audi in which it wouldn't crank. AAA came out and banged on the starter before giving up and towing the car back to my house. Checked the 12 volts wire to the starter and there was no voltage. Connected a wire to the solenoid and touched the other end to the positive terminal of the starter and the engine cranked. Put the key in the ignition and turn it to the run position. Crank the engine again and it started. Discovered that about 1 inch away from the terminal that connected to the solenoid the wire had broken. Splice a new wire to a point that was still good and that fixed the no crank situation.

The battery in the remote key is only used to transmit the 315 MHz (or 433 MHz in Europe) radio frequency from the remote to the aerial in the rear right cargo window to initiate FZV/DWA (central locking/anti-theft alarm siren system). See the WORKSHOP HINT in the lower right gray box below:
