I did not find it necessary to pry the pieces apart, but your experience may very.

There are also 2 screws up near the top of the picture past the wheels. Note, there are 2 wheel screws as well, but you don’t need to remove those. You want the 2 deepest screws at very top. Also note, the top left most screw circled in the picture above is the only screw longer than all the rest because of the design.

You can by a tamper proof hex set for like $7 on Amazon.
