I have a 2005 cadillac cts-v it doesn't even attempt to start key turns fully no noise when turned to start. Security light was flashing and tried unhooking the battery and went to try starting it an the light went off but still nothing drove the car a few hours earlier and it worked fine thought it might just be something with the woteing or a fuse thought someone might be able to help also none of my radio or some lights turn on my headlights work and horn my key fob also when trying to lock
will make a sound like it is locking but won't actually lock
