There is also an "autolock" feature that was not turned on from factory.
This feature allows you to simply walk away from vehicle after exit. It will lock itself after you (with 3 secs if away, 30 secs if you stick around within proximity). You will hear a beep for confirmation so that there is no mistake. Very cool.
Have your dealer turn it on for free for you.
Sounds like a neat feature - I might need to enable it for my wife (she's never been too keen on locking her car).
One question I have, similar to the topic at hand, is related to keyless entry, using the fob to unlock the car and then enter it some time later.
Over Christmas, I was at my parent's house, and needed to put something into the car. I picked up my keys, pressed unlock (saw the lights flash, indicating that my request was accepted) and then gathered up all the stuff I needed to carry out. As I was walking out, leaving the keys inside, I heard an audible (thunk) of the doors locking. First, I thought I imagined it, walked up to the car and pulled the handle... sure enough it was locked.
What happened? Does it have a predetermined amount of time that you must open the door prior to it relocking itself for safety? It did the same thing when we were at church that same weekend, unlocked it from afar, but sat around talking and the car was locked when we approached.
Do you think we might already have this feature enabled, or is what I'm experiencing something different?
