Morphology
The meaning 'vital knowledge needed to navigate street/urban life' is directly built from 'key' (fundamental, essential) combined with the domain marker 'of the' + 'street' (urban milieu), so the overall sense is compositionally predictable. Although slightly colloquial, it follows the common 'key to/of X' pattern found cross-linguistically, so a B1 learner who knows the constituent words would likely infer the intended meaning.
Etymology
The phrase key of the street comes from the image of a physical key that opens doors on the street. If you have that 'key', the right skills, friends and local knowledge, you can move safely and get things done, so it means 'vital knowledge to survive and succeed in city life'.
