Are any of the exchanges still a proprietary fill that needs a special key?

I have never seen a propane tank that required a "special key" to refill.

This may have disappeared. I think it was the TS2 valve that had a magnetic interlock required to refill.

Blue Rhino 2004

I had one of those Blue Rhino tanks one time. Uhaul could not refill it, and when researching I learned about the Blue Rhino locked valve. I came on this forum to complain, and someone told me it was impossible because Blue Rhino had quit doing that.
