This practice is a variation on the Freedom of the City tradition , and has a similar symbolic meaning ; evoking medieval walled cities , the gates of which would be guarded during the day and locked at night , the key symbolises the freedom of the recipient to enter and leave the city at will , as a trusted friend of city residents . </P>
