Locked vs Unlocked and battery usage

I read in a recent thread that leaving the car unlocked will draw on the battery more than a locked car. This doesn't make any sense to me as you would think the alarm system would use additional power. Can someone elaborate on this??

I suggest that you read the owners' manual. The active alarm system monitors the doors, luggage compartment, engine compartment, glove compartment, passenger compartment, and so on. Seem like a lot of monitoring--will take power to do this. Recall, too, that the remote control standby function switches off after 7 days, to save power. Take a snow-day, and read the manual that Porsche carefully prepared for your car.

With respect... read the manual. An unlocked car draws more power than a locked one.

An unlocked car without the key on the ignition uses the least amount of current from the battery.

If locking the car in your garage for a long time I'd suggest leaving the window open just enough to get your hand in there to open it if something goes wrong battery-wise over time. You never know.

Battery Maintainer - then it doesn't matter. Unless you are talking long term parking at the airport - I'd go for locked in that case, regardless of power consumption - and I'd keep the windows up.

Interesting...I've always understood otherwise. I conducted my own experiment a while back (from sheer boredom) using the battery maintainer. Though unscientifically, I found it took less time to recharge the battery from an unlocked car than a locked one. With the maintainer unplugged, I left the car unlocked for 48 hours, then recharged it to full. I then compared it to being locked for 48 hours.
