Good tips Tim. Thanks.

I ldidnt turn off the engine a few times, when my wife goes grocery shopping and I waited in the car with the kids. I found that my engine stayed off for about 7-10min (although I had the DVD player on for the kids, so i dont know if that shorten that off time).

I think to lock the door with the keypad, it's to press 7-8 and 9-0 keys simultaneously (is it 7-8 and 9-0? Anyways, its the two rightmost keys). I think the manual tells you somewhere. IF you do that, make sure you remember your unlock code! I did that once, and my wife had a "knuckle-head" look, and unlock the car with her remote. Now we programed in our own code, so we cant forget.
