<p>According to the city, "The Key to the City is a replica of the key to an original door that remains in City Hall, but it no longer functions as a key. The keys are symbols that New York Cityâs gates will always be open to the crew of Flight 1549. The Key to the City is 5 ¾ inches long and made of gold-plated pewter. The last recipients of Keys to the City were the players, coaches, and owners of the New York Giants for their 2008 Superbowl victory."</p>
