You highlighted the wrong part of my post.
"I bet walk away to lock has something to do with not so great battery life in the fob"
How does the car know you are leaving it? I shut the car off, and walk away and the doors lock. There could be some type of passive transmission going on.
I highlighted the correct part, the part I was commenting on.
How does the car know you're walking away? Easy, the system transmits for a short amount of time (30 seconds or whatever) and then times out.
