Yes,
Scenario:
01.) Unlocked VX
02.) Went to Open Trunk
03.) Dropped what I was holding into the trunk
04.) Walk around to open driver door
05.) [BEEP]!
06.) Doors locked right as I pulled up on the handle!
07.) Realizes the keys are under everything I dropped in the trunk
08.) Starts to rain!
09.) POURING cats and dogs now
10.) Realizes house keys are on same key chain.
11.) Locked out of Car and House!
That wasn't a good day for me...
Now if I was able to get into the house, all I would have needed is a wire coat hanger... You would be surprised on how easy it is to get into the VX with just a coat hanger!
As for shutting it off, Nope, No Idea. I wouldn't want to do it anyways.
