You can reach in with a pick and push the crane lock forward to unlock it from the ejector rod.
Just out of curiosity, I tried that and found that there is not enough room for a pick to reach in there (something I suspected when I saw that post), and if there was, a pick would not likely be able to push on the slanted portion that lock to get it to move.
Nevertheless, being of the curious type, I took one of my K frames, I found that a utility knife blade (Stanley, etc.) will fit between the crane lock frame and the ejector rod. When it is pushed in at 90 degrees, the blade camed the angled locking pin out of the recess in the ejector rod. It is dependent upon if the rod's angled surface is in position to be accessible to the knife blade.
