'16 Dart Evo All Standalone stopped working

Question

I installed the Evo All with T harness in my 16' Dodge Dart last year before winter.  Install was done correctly, and the unit worked flawlessly all winter without any issue.  I went to use it on a hot day to cool down the car, hit Lock X3, and nothing... Looked into it today, and the blue light flashes with input, the Red light comes on and clicks indicating its starting the process, then the Yellow light comes on also for a period of time, with nothing happening...  I even reset the unit and reprogramed all over.  I get it back in, and the same results... the car will not start remotely.  Any help?? I love this unit, but not right now!
