Here is a range of key outline clip art. It includes a variety of keys including some simple and some ornate ones. The clip art is in PowerPoint vector format so you can scale it and change the colours.
A key is a fastening device used to open a lock or door (i.e. unlock or lock). A typical key consists of two parts: the blade, which slides into the keyway of the lock and distinguishes between different keys, and the bow, which is left protruding so that torque can be applied by the user. Types of keys include house key, car key, master key, control key or skeleton key.
This clip art could be used for presentations on security, while some of the more ornate keys almost look like they belong in a fairy tale – they could be used to present a magical story or fantasy-genre poem on paper.
