In modern days, we have adopted the Key Pendant as a symbol of entrusting someone with the access to one's "Heart of Hearts". The "Key to a Heart" is given in the same fashion as the “Key to a City" has been given for ages. The practice of presenting a "Key to the City" to an individual can be traced back the Middle Ages when it was a symbol of the City's intention that the recipient was free to come and go at will. Today it is considered a symbolic gesture, bestowed upon distinguished persons and honored guests for achievements of the highest importance. Giving someone the "key to Your Heart" will be a symbol of expressing a special trust and commitment. In present days, when in a romantic relationship, two will exchange keys from their homes as an act, that signifies the moment when a relationship has been taken to the next level and the foundation of a life together has been laid.
