for Everest conventional cylinders and
Primus Levels 7, 8, and 9
D Family Restricted Keyways (not shown)
D Family keyways are end user restricted keyways. They are not stocked by locksmtihs or other dealers. Conventional
(non-Primus) cylinders with D Family restricted keyways offer economical patent protection but no geographical exclusivity.
All orders for D Family keys and blanks require a letter of authorization from the end user.
The D Family keyways are only available at Primus Level 9 where product is shipped directly to the end user or his
designated agent. Primus cylinders add the geographical exclusivity of the side bitting as well as the high security features
of the finger pin and sidebar mechanism.
By definition, all Primus keys are restricted. Primus keys are downward compatible to operate Schlage
conventional
cylinders with compatible keyways. Key blanks for Schlage Everest
conventional
cylinders with C Family keyways
(above) are openly available to locksmiths and contract hardware dealers but not normally found in retail stores that
duplicate keys.
