To do that, the car would have to continuously query for a fob, and that would drain the battery. The way ours works, the car doesn't query for a fob until you do something that requires fob authorization, such as touch a door or hatch switch, or attempt to start the car. That way neither the car nor the fob are exhausting their batteries just on the off chance you might walk by.

I've used it since the day I picked up the car (daily driver for about 15 months now). Never had a problem and have never locked my fob in the car.
I personally like the horn 'toot' as confirmation that the car has locked. I shut the door and walk away. 8 seconds later, I get the confirmation 'toot'. If you don't want the horn to sound when you are at home, just press the lock button on the fob before the 8 seconds are up. This will lock the car and cancel the confirmation 'toot'.
If you leave the fob in the car and close the door, you will get 3 'toots' to let you know that you are trying to do something stupid. As noted in other posts, the fob will not be detected in the rear hatch area. So, don't throw your for in the back and then close the hatch. This is equivalent to throwing your keys in the trunk and shutting it in any other car.
Passive lock does not cause any battery drain.

I have used the Passive Lock System from day 1 with no problems.

F.O.B. originally was a notation on a purchace agreement or contract which meant Freight On Buyer to make sure both parties understood it was the buyer paying the shipping cost
I have not changed how the passive lock works from the factory, or maybe it was the museum who set it, don't know if they do it different. Works fine for me

It is very repeatable on my '07. I know because I have a fan I start with a switch in the garage on the passenger side. If I walk 3 feet forward of the passenger handle it locks. If I stop short it doesn't. What I need to experiment with is walking away from (as in walking around the back) and then return to the driver's door within the time it was supposed to lock and see if that will also confuse it.

Actually I think fob meant 'free on board' back in the day,which did spell out who was responsible for shipping charges. No matter, mine works fine!

I do. I always listen for the chirp to know it worked. I didn't use it on the C5 because where I kept my keys caused it to cycle sometimes and that was annoying at 0200!

A locked car doesn't draw more current. All it means for a C6 to be "locked" is that the door latch will not activate when the door button is pressed if no fob responds to the ping sent by the car at the same time. It's just a software state.

F.O.B. stands for "freight on board." It designates that the charge for the item being shipped includes loading onto the shipper's truck, railroad car, etc., but not the shipping itself. This is especially important for heavy items -- if for example you're buying a milling machine, who's paying the rigger to load it?

i've set mine to auto lock flash only. the horn keeps bothering me specially if it's in the garage. so loud sometimes i get startled 
. also it will honk to remind you if you close the door while the key is inside the vehicle.

I could have sworn I read somewhere that the interior/ map lights can be programed to do that... Those s/b noticeable in the dark.

The danger with automation is thinking you're done when you've only covered 95% of the use cases. The devil's in that last 5%.

You've both got the acronym wrong, but the more-or-less the right definition.

The meaning, of course, is the same.

On the C5, the passive lock seemed to work when you walked away, didn't seem to be a time limit. Is that not the case on the C6? I love the passive locking on the C5, one of the best features. I hope GM didn't botch up another good feature. Removing it on the later C5's was an especially good move.
