Although a key necklace often serves as a stylish adornment to complement an outfit or other jewelry, it also holds significant meaning for the person who wears it and those who give one as a gift. Some types of key necklaces are meant to convey a specific meaning, while other styles have multiple traditional meanings tied to them.
A heart key necklace often comes with a heart-shaped lock on a separate chain. The gifter keeps the lock pendant to wear around their neck, then gives the key to a romantic partner to symbolize holding the key to the giver's heart. With or without the accompanying lock, the heart key's meaning remains the same.
A lock and key worn together on the same chain represents security. In modern times, people often give loved ones a lock and key necklace before moving or going on a trip as a token of safety and protection.
In many traditions, keys and key shapes are said to hold beneficial otherworldly properties. Designers on Etsy craft magical key necklaces with these attributes in mind. Depending on the maker's intention and the key's motif, a mystical key necklace might be offered as a wish for protection, good fortune, wisdom, or hope.
The easily recognizable form of a skeleton key often signifies spiritual protection or unlocking the mysteries of the universe. People often wear skeleton key necklaces as amulets for inspiration in their personal growth journeys.
