So, you have the same behavior with the new immobilizer, Craig?
That points to something on the car being wrong. Probably door latch issues. I still think you both have bad door latches (probably on both doors).
Also, the connectors in the door frames are known points of failure. Moisture can get in and corrode the pins/sockets. They can be cleaned with contact cleaner.
