Is there a Unicode glyph that looks like a "key" icon?

Question

Unicode has a million icon-like glyphs, but they're not always easy to search by, since I don't always know what they look like.

Is there a Unicode glyph that looks like a "key"? Or is there a symbol that's used in database circles to mean "primary key", which is in Unicode?
