Keyed Alike or Keyed to Differ?

Locks that are ‘Keyed to Differ’ have their own set of keys that will only open that individual lock.  For example; if you purchase 2 ERA Fortress Sashlocks ‘to Differ’ both locks will come with their own set of keys.

Locks that are ‘Keyed Alike’ have a set of keys that will work on both or all locks.  Using a similar example to the one above; if you purchase 2 ERA Fortress Sashlocks ‘Keyed Alike’ the locks will come with one set of keys that open both locks.  In certain circumstances there are obvious advantages to having locks ‘Keyed Alike’ such as having your front and back door on the same key, reducing the number of keys to be carried around, etc.
