Anti-theft Devices problems of the 2012 Ford Taurus

The problem has occurred multiple times and with no luck of diagnosis. But my vehicle has lost all electrical function lights, dash cluster, heat, etc. Has done this on different occasions but seems to fix itself but then does it again. With that being said now on top of that my vehicle is stuck is now stuck in anti theft mode where the vehicle is no longer drivable. I can not start the vehicle, I have had keys reprogrammed and the car look over multiple times with absolutely no help diagnosing the issue. I have done some research on my own and found that there are a lot of other people who have been having the same problem with no success getting the problem fixed. The first time it occurred was 7/01/17 and has continued off and on up to date and has now like stated earlier has now manifested into the anti theft not allowing car to be started rendering in non drivable at this time.
