Probably referring to the nostrils in the rear fenders. It amazes me how people are in such a damn hurry to drill the tumblers out if they loose a key!! I had a car a number of years ago without a trunk key and I didn't drill it! I went to a nearby locksmith who came out of his shop with an uncut key, a pair of vicegrips, and a hand held key clipper. He stuck the uncut key in the lock and cranked it back and forth with the vicegrips leaving small marks in the key. He clipped the key until it rotated and unlocked the trunk. This was now a pattern to cut a new key on his key cutting machine inside his shop. Aluminum keys work great for this as they are soft. Being this hastey to drill tumblers means one thing, the drill bit would be better off being placed at the side of the head or middle of forehead. If the key turns but the trunk latch won't release, well that's a different story warranting drilling a hole through the emblem.
