Could be issue with ignition switch or security system? If the starter motor won't crank, check voltage circuits at the starter. Usually two voltage circuits, one is battery voltage, hot all the time. The other voltage comes from crank position of ignition switch.

You can try this re-learn procedure, if that doesn't work you will need to bypass the security system. I hope you bought the wire harness adapter for that vehicle. They need it.

Perform the re-learning procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY light, after approximately 10 minutes the light will turn OFF.
4. Turn OFF the ignition, and wait 10 seconds.
5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes
6. The vehicle is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
7. Start the engine (the vehicle has now learned the Sensor Data Code and/or password).

Once you get them out, the door pops off of those little white plugs in most new cars. After that you need to purchase a power window regulator. That is what broke that made your window fall in. It looks complicated, but it is only three or so bolts to change out. If you broke the window, Call around the salvage yards to try & locate a replacement.
