2012 is this way, two tabs on the rear ones have to be pressed in to remove them. Think you need three hands to do this, but manage with two somehow. Have to be removed to drop the rear seat backs.
Fronts only have one tab, like said, the other one has a pin hole in it. Cut off paper clip in a pair of pliers helps, a third hand to pull it out definitely helps. But they are super easy to install, just slide them back in.
