But I guess this theory can be proven or disproven by looking for parasitic draw when the car is locked vs unlocked...

I never use to lock any of my cars when they were parked in the garage until I bought my 535. I would park it in the garage unlocked and the next day or a couple of days later the battery would be dead. I thought I was leaving a light on or something else. It continued doing it until I took it to the dealer and they replaced the battery, the same thing continued happening, then a service tech asked me if I was locking the car and turning on the alarm, I said no, because I was parking it in the garage. That`s when I was told to lock it and turn on the alarm so the car could go into sleep mode. Guess what? The battery was not dead the next day or a few days later after that. Coincidence? Maybe.
