You will need to remove the screw that holds the lanyard strap so the bag can lay flat. There is also a strut that needs to be taken off the post, a flat tip screwdriver will make this easier. There will be 3 screws that hole the 3 pins in place. Remove each screw for each pin and use a pair of needle nose pliers to pull the pin out. An extra set of hands makes it a little easier.
