There are actually 2 rivets holding the swing away crest cover. Drill them out, then the cover falls off. THEN, there are rivets holding on a plate at the bottom edge of the trunk lid. Drill out those rivets, then you can get access to the slide on fork like retainer holding the lock cylinder to the lid. All of this is to prevent trunk theft. On my crest, I simply used self tapping stainless screws to hold it on. Same on the plate at the rear of the lid.
