Another thought (yeah, I know: Sigh, him again!):
Those keyed quarter turns might seem like a good idea, but I'd prefer not to have to use a key on each place to merely lift it. Rather, I figure that if a lock is needed, why not get one of those locks used for cockpit lockers (twist and lock) or cabinet drawers?
I mean, you wouldn't need to find the key every time just to open and close the thing, but could use it if you wanted or needed to?
I was thinking of using ONE keyed fastener per cover. Like using just one locking lug nut on an auto wheel.
