my girlfriend gave my brother my car keys to move my car, he came in telling me that my car wouldnt start and he doesnt want to "mess" with it

on top of being woken up on a saterday morning i come to find out that my car is broken

i tried starting my car and the ignition would just keep going and i noticed the red and green lights were flahing on the rear view mirror

this has happend before so i lock the car from the inside, and try unlocking it from the outside (it worked before)

but now my car key doesnt lock or unlock from the outside!!!! i cant hear any noise when i stick the key in. if i turn and hold to the left NOTHING!

if i turn and hold to the right Nothing! Someone Help
