What Is Keyed Alike and Keyed to Differ
What is Keyed to Differ?
This means that all locks have different key combinations, ie. a key from one lock will not fit any other lock in the same group, there is usually a limit to the total number of differs available for a particular lock group but is generally high and not normally a problem for most applications.
What is Keyed Alike?
Basically keying alike means that locks in a set or 'suite' have the same key code, ie. any key fits any lock. This is convenient where a large number of locks are to be used by the same group of people or person but can be a problem if individual security is important.
