A retired locksmith is leaving the door open for anybody who wants to make themselves at home in various areas of New York City’s infrastructure.

Daniel Ferraris, 69, of Union City, New Jersey, is reportedly not asking questions as he sells the keys, which have some crying foul over a possible security breach.

Ferraris recently collected $150 for a ‘firemen’s key ring’ – a collection that can grant access to places like elevators, subway station gates and electric panels in pretty much any building in the Big Apple.
