Keys can symbolize status, as they may show ownership of property, the more keys the more property. Â At a more basic level, keys have the ability to open and close, giving access to what’s locked behind. Â Literally it can be access to a house or a box. Â Symbolically, it can be to another realm like wisdom or success.
