The ONS 15454 door locks with a pinned hex key that ships with the ONS 15454. A button on the right side
of the shelf assembly releases the door. You can remove the front door of the ONS 15454 to provide
unrestricted access to the front of the shelf assembly. Before you remove the front door, you have to remove
the ground strap of the front door (Figure 1-5).
