Ancient padlock found on surface of Mars

On November 10, 2018, the ufologist Scott C. Waring found a giant padlock on a picture of Mars (Sol 2222) caught by rover Curiosity.

He claims:

I found this giant padlock device on the surface of Mars in the latest NASA Curiosity rover photos. The photo just came out today and there are three photos with this strange artefact in it. You see that it has two extended if they were pressed together to lock and the other side was the protective shell of the padlock. Very cool. If NASA would give control of the rover over to me for a month. I would win the Nobel Peace Prize for science ten times over.
