Key symbolism is for real. They’re emblems for so many things – eg: Hekate and Mercury.
I hired a Gemini locksmith who naturally knew everything and these are some of the things he told me:
*When you can’t get in your front door because the key does not work all of a sudden, it is time to re-examine your life.
*Keys are an initiation. You can see that in all the fairy tales.
*Keys have the power to open or close things, so they are sacred. You can lock something up forever as in secret inside of a vault, or you can open the door to a new dimension.
*The Ancient Romans invented keys. It was one of the keys to their success as an empire and a big set of keys used to be a status symbol.
*The keys were often ornate and inscribed with magical symbols. Locksmiths in had allegiance to the temple of Athena.
* An obsolete key on your key ring or even just in your house somewhere is not right. It symbolizes that you have the key, but you don’t know what it is for, there is no lock for it. It should be thrown away or even better, buried.
*Everyone should have a master key.
*Always heed key symbolism or omens around keys. Notice, for example, when someone takes your keys ‘by mistake.’
