Trim rattles

[JohnL]

I've got a rattle and I've managed to track it down to the key.

If you have the key in the folded position and shake the key you hear the rattle. When the key is flipped out you can hold the blade part of the key and wobble the black plastic part there is just over a mm of movement. So as you drive down the road the key rattles quite badly not sure if the key can be taken apart to resolve this or not.
