How can i get a new key for my mailbox?

So my drivers license and any type of bill with the address on it ? Does it have to be my name on the bill or no?

Take your drivers license with a bill to the local post office,while there tell them you wanna put your mail on hold this way the post office will hold your mail and pull any mail that may have been delivered in your box already.. they will have you fill out for a new key .. when it come you will have to pay $30 but you get 3 new keys.. I hope this help. You can also check your mail at the post office once you put a post office hold on it.. BLESS
