Is there an actual key symbol on the keyboard?

A literal key like one used for a lock. You can understand why this is so difficult to search.
I think I have seen one before. I feel like there should be one. I've searched through websites and the character map. This was a last resort. Will someone please just make one for me? :/

No, my friend.

search for alt codes or if on windows start>search character map find your symbol
