Oh thats extremely weird as i tried to put the keys in those hole things ALOT of times but they never worked for some reason, Must have been a bug then
You have to ungrab the key in front of it, it doesn't just grab it by force from your hand (might do a patch)
Probably makes more sense to just forcefully take it from you when you enter the radius of the placepoint
Hey, I have taken your feedback into account, I put a patch which should be less confusing for players !
