@sam_boo26 it is the key that I can't loot on the body as the icon for the key is showing on his body or at least around it but I'm not able to collect or even get a prompt to collect it

I'm having a problem with collecting the last of 3 keys for the Jorvik chest. I know where it is and how to get it but when I get to it I am unable to loot the body, which is how you get the key. It also shows that its there but it just won't allow me to loot the body. I've tried shooting the body so it moves so I could possibly collect it that way but nothing works.
