To install the lock, you'll need a Torx-X security bit, size T-10. (If not sure what this is, ask the guy at Sears or Autozone or Schucks.) The screws for the lock are inserted on the underside of the latch. Dry fit everything until you get the hang of it. The flange that swings over from the key works in conjunction with the lever that locks the bag in place.
Once you have mastered this, remove the little screws holding the lock, then put on a tiny dab of Loctite on the tip and re-install the screws. Emphasis on tiny dab--you really don't want this stuff getting on plastic or other places, just a bit on the threads of the little screws.
How important is the Loctite? We should start a poll of when the first '06 will be to lose a lock and the bag due to lack of it... :bigeyes: Once the bags actually arrive, that is...
