With an ugly green tag indicative of it being labelled to be a spare? Seems odd to me. Was there not also a shot taken of items in bottom of sunglasses case showing bunches of keys with tags on them? Just glanced over in trial. But presented just the same by Nel as if it was pertinent. Like a cache of spares?
Did Reeva really lock it with a key or did she just lick it and Oscar had to go back to room to get it?
I suppose Nel glossed over it because it's not really that important. They were key only locks. They needed keys to be locked and I guess probably had spares.
