Question 2009 Cooper S Will crank but not start

I've done all the troubleshooting I am able to perform. I've replaced a poor battery (4 yrs old in AZ). Replaced a questionable fuel pump relay. Verified the fuses in the engine bay are good.

The car was working when I got a jump start to take it to an appointment at a dealer for an oil change. Stopped for a errand and the car would not restart again, even when jumped.

Cannot access OBD codes as all my scanners cannot connect. Inside, on the tach display, the only item showing is the "key" symbol.

I've read somewhere the ECU, which has the VIN, the Fob, and the Rolling code generator must all match in order to have the ECU kick on the fuel pump and the ignition spark. 1) Is this true? 2) Is there any way a DIY-er can reset this so the car can stop being a really expensive lawn ornament?
