Anti-theft light issue?

Hello, I drove my edge home one day a few months ago. I went to leave a few hours later for work and the anti-theft was blinking rapidly and had a no crank no start. So far, I have replaced the ignition switch, PATS transceiver and I bought a preprogrammed PCM. It still has all the same symptoms whether I replace everything or not. I'm guessing it never had problems with any of these components. I have lost my job and almost my house because of this. I live in country so I really need this car to run. I just don't get it. I have checked all fuses and power and ground pins on PCM. It will not connect to FORscan to try to relearn the keys it won't do anything but blink anti theft. Please help.
