Question: 1 / 400

What mechanism is used by the Schlage Primus side bar to function?

Magnetic pins aligned by a unique key shape

Finger pins that are positioned by the side milling of the key

The Schlage Primus side bar operates using finger pins that are positioned by the side milling of the key. This mechanism is pivotal in the unique security features of the Primus lock system. The side milling on the key allows for variation in pin height and placement, which distinguishes it from standard pin tumbler locks. When the correct key is inserted, the finger pins align correctly, allowing the side bar to retract and enabling the lock to open.

This design enhances security by adding a level of complexity; not only does the key need to lift the standard pins to specific heights, but it also requires the unique side milling to engage the finger pins, making it more resistant to unauthorized duplication or picking. Using this dual mechanism, the Schlage Primus system provides robust security, leveraging precision engineering to ensure that only properly designed keys will operate the lock.
