Mine has never worked without the car key either. It always drove me nuts and to this day I'm still not sure how it's actually intended to work.
Thus far from the ETK (I've been distracted by other things, namely how ****ing stupid the armrests are to disconnect) I can't tell which pieces of the box itself are actually sold separately. I presume that the door/drawer assembly itself is all one piece and from what I can tell what's different b/w coupe and vert is just the handle, locking mechanism, and an extra wire/sensor/whatever that connects it somehow to the trunk and rest of the car/lock mechanism.
Perhaps you think multi-million dollar ad campaigns make a beer taste better. Perhaps you're mouthing your words as you read this.
