Tonight when i was sticking the key into the ignition, i missed and stuck it into the area around the ignition. This caused something to spark and when i started my car i noticed the radio did not turn on- no lights or anything. a few minutes later i realized that my automatic seat belt had not came back either, and that when i opened the door the "door alarm" did not come on either. I am not sure what I did or how to fix it, I am hoping someone can help me!

 

You probably shorted something with the key. Check the fuses in your driver side under dash fuse box. The radio fuse is at location No. 11 (10A) fuse. Also check the other fuses. There may be some spare fuses still in the fuse/relay box which you can use.
