I think Fotodiox still makes them and sells them new. That's where I got mine.
I needed it when I was using my V lenses and tubes on a Leica S.

When I use extension tubes with my Flexbody, I take my lens and other tubes off carefully, but it is not unusual to have to use the Camera Key (Unjammer) to get the cocking mechanism back in place. Very common issue, that's why the Camera Key was made.
You can use a screwdriver too, but I have had the Camera Key for decades. No longer made, but you can find them on eBay:
