By definition, all Primus keys are restricted. They are downward compatible to operate Schlage conventional cylinders
with corresponding keyways. Schlage Classic conventional cylinders may have keyways which are openly available as
shown above, or they may be restricted (without patent protection) and require a letter of authorization from the end user.
Not all Classic restricted keyways are Primus compatible
.
Multi-section keys and
the all-section key are
only avialable at Primus
Level 2 and above.
