Well,
I checked to see if the problem was due to using different FOBs. OOPS, I couldn't replicate your complaint.
On MY car:
If the car is "ON", with the car doors open, I cannot lock the car doors using either the power door lock switch OR the manual door lock. (The locks operate, then immediately unlock again.)

The only way I could have the door stay locked was to use the mechanical key.
Are you SURE that BF actually turned the car ON and not just in the archaic "ACC" position? (Never mind, I see that you said that the car was actually running.

)
Second item: is it possible that YOUR key was being blocked by your body?
Two ways to keep this from happening again (needing to pre-warm-up the car): 1) park the car in your front/living room overnight. (Makes a GREAT conversation piece.) or 2) move to Florida (problem, it's one hell of a commute).
