I wrecked into a small ditch ripped my front clip off. The car was still running after I turned it off to get it pulled out. Tried to start it back up and no power to starter. Then I took the module out from under the steering wheel and now tried again and key would not turn at all.
Do you
have the same problem?

The module under the steering wheel is part of the key interlock system. It does not allow the key to turn unless the car is in park. More than likely you will need to do the repairs to the front and check all of the fuses and battery cables. The damage likely shorted multiple systems and until that is sorted out they will just keep blowing fuses and not working.
Without actually seeing the vehicle up close there is not really much that can be done because we cannot tell what damage has been done and to what systems.
Sorry about the car.

It tore the front end off where the fog lights are and ripped hoses came off the windshield wiper box ripped the fog lights off as well. By this can you tell any more and could it have set my security system to where it will not work or should I just go through the fuses?

I would start with the fuses. But I would also get a good source of information that has the wiring diagrams and colors for the front end. Then I would remove the damaged parts and the sub harnesses for them. Like the fog lights, They are normally a sub harness that plugs into the main harness for the front lighting. If you unplug all the damaged and even pull the torn/broken pieces off as you go you can create a shopping list of parts and fasteners to repair it. Both Alldata and Mitchell have DIY access portals that give you the same information I have here, they run about forty dollars for a full year of access for a single car.

There are both anti-theft and impact sensors that would keep that car from starting. Impact the would do that damage could easily trip both systems.
