Hi all - '04 G35 coupe owner here. There is a small, body-colored plastic piece that fits in over the keyhole on the driver's side door. Mine fell off today when I got out of the car, and while I can sort of put it back, its not really attaching firmly. Is there a proper way to attach this? I suspect probably a plastic tab or something on the inside broke off, but I can't tell for sure - if it did break off it was a clean break and its not obvious. Assuming nothing did break off, is there a proper way to reattach? Otherwise, is this something I can easily order from the dealer's parts department? Thanks in advance for any help.
