A short post but an important one: While you’re making a spare key when re-keying for your new tenants, be sure to make a spare mail key for yourself! It will only cost a few dollars (and likely only need to be done once), but having the post office re-key your box is a major headache, time consuming and costly.

Is this a mail key to use between renters or before renters move in?
