So for if any reason this is what your problem is, I recommend checking out the lock on the glovebox. When I took mine into Mercedes they couldn't figure a darn thing out for 3 days. Apparently their is an electronic lock switch in the glovebox that if it goes bad, and you try to lock the door, it'll sound the siren until you unlock the door again. Cheap fix, or you could just unplug it. Not exactly sure where it is because I wasn't the one who did it, but after unplugging it (Until the new part came in) I had no problems with the siren whatsoever.

Just thought I'd throw that in here just in case someone has given up hope..
