Pinned here for me too with the following caveat.
While pheasant hunting with my Wiegant shotgun recently I noticed that the pinned key had slipped out. When I pushed it back in it had no tension so the hunt was over. When I got home I removed the barrels and could see that one of the arms at the center of the key was broken and the other side showed a faint crack. There was no way to remove the pin without doing damage to the wood. Fortunately, I was able to break the other side of the key and remove the head of the key from the slot.
I was able to get a jeweler’s saw blade into the slot and cut the pin removing the section the slot width in length, drive the pin down and repeating the process removing the pin entirely without damaging the wood.
I then made a new key out of 1075 steel, then hardening and tempering it. I have not pinned it yet but it will be a screw with a slotted head for whatever reason it might need to be removed again. I have an original German cape gun that is done this way.
