2007 Ford Taurus

2007 Ford Taurus 6 cyl Front Wheel Drive 46000 miles

I have a 2007 tuarus that was running just fine, until a couple days ago. The car wont turn over now. I can jump the starter, and it cranks. It just wont start. I know it's a security issue. The day all this happened the theft light quit working. It doesn't flash or come on period. Iv'e tried everything BCM, and a new key and transmitter. Any suggestions would be appreciated!
