What does a key symbolise? Throughout history, keys have represented far more than simply opening a door. Key symbolism is often associated with opportunity, freedom, knowledge, love and unlocking new beginnings.

A key can also symbolise access to someone’s heart, making it a particularly meaningful symbol of love and trust. It can represent discovering something hidden, unlocking potential or opening the door to a new chapter in life.

From ancient history to jewellery worn today, the meaning of a key has developed across cultures and centuries. Let’s discover the history and symbolism behind this fascinating little object.

The History and Meaning of the Key Symbol

The key became a useful practical device in both the Western world and the East at around the same time – though they did not exchange ideas. The Egyptians were said to have first used key-like devices around 4,000 BCE.

The Bible itself also mentions keys in several important passages including chapter 3 of the Book of Nehemiah and chapter 22 of the Book of Isaiah.

In Roman society, the goddess Diana often had a relationship with keys as she was considered the Goddess of Hunt and was known for her protective skills.

Keys are important both biblically and spiritually as well as practically.

Skeleton Key Meaning & Symbolism

Of all the keys that one can own, it is the mythical skeleton key that is the most prized at all. This is the so-called ‘master key’ which is able to open any number of doors.

They are both metaphorical and practical, allowing you to open physical doors wherever you go and access new opportunities and new challenges in your life that would otherwise have remained closed.

The Key to the Heart – A Symbol of Love

For centuries, the key has been associated with love, trust and devotion. The idea of giving someone the “key to your heart” symbolises allowing a special person into your life and placing your trust in them.

This romantic meaning has made the key a popular symbol in jewellery. A key necklace or charm can represent love, a special relationship or the beginning of a new chapter, making it a thoughtful and meaningful gift.
