Locks and keys hold many meanings in the tattoo world. They can speak the value of what is locked away, and imply restricted access to a certain aspect of a person and their life. A heart-shaped lock with a keyhole can stand for a person's search for their one and only true love - a person that will possess the key to unlock their heart. It can represent freedom after a time in time in your life when you’ve felt imprisoned. It could also represent the act of unlocking a new chapter in your life. Whatever the reason for a lock and key tattoo, I have always admired them.
