2002 E39. I have recently been leaving it in a rented space in a lot
close to my home at night. Four times since I've begun using the lotI
have returned to find either the driver's door or all doors unlocked.
First, even the second, time, I figured I didn't lock it. But the next
two times, I know it was locked when I left it.
Anyone have any ideas what might cause this?
I've considered that someone parking nearby has the same key
frequency? Not likely, but is it possible? Anyone understand the
security to know if it's possible. If so, what's the fix? Parking
where I live is near impossible at night and it took me a long time to
get this space, so I cannot easily move to a new space somewhere.
Or, can there be something in the car itself that triggers the locks?
Some weird short?
I have one key that no longer works on any of its remote functions and
the other that has lost some of them (resetting the seat position for
example) but still works the door locks. Could that be related?
Help please before someone else discovers that the car's unlocked
regularly. Not that I leave anything of value in it, but....
much thanks for any advice.
