Schlage N523-123 – Frequently Asked Questions

1) What exactly is the Schlage N523-123 part?
The N523-123 is a cylinder tailpiece and actuator assembly for Schlage locks. It is the mechanical linkage that transfers key rotation from the cylinder core into the lock chassis. You are buying the tailpiece and the actuator together, not a cylinder and not a key.
2) Which Schlage cylinder does the N523-123 tailpiece work with?
It is made for the ND85 conventional cylinder and nothing else. If your opening uses a different Schlage cylinder or an interchangeable core, this tailpiece and actuator is not the right part for it.
3) My key turns but the latch does not retract on a Schlage ND lock. Is the tailpiece the problem?
That symptom points at the linkage between the cylinder and the chassis, which is exactly what the N523-123 tailpiece and actuator is. When the actuator is worn or the tailpiece is damaged, the key rotates freely without driving the lock. Replacing the assembly restores the mechanical engagement on an ND85 conventional cylinder.
4) Is the N523-123 a drop-in repair or does the lock need modification?
It goes in as a direct replacement for the worn tailpiece and actuator in an ND85 cylinder assembly, with no modification to the lock called for. Service is a matter of pulling the cylinder, swapping the component, and reassembling.
5) Does the N523-123 come with a cylinder or keys?
No. It is a replacement tailpiece and actuator only. The ND85 conventional cylinder, the core, and keys are all separate; this part is the internal linkage you install into an existing cylinder assembly.
6) Is this a residential part or rated for commercial door traffic?
Commercial. The N523-123 is a commercial-grade mechanical lock component, used in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings.
7) If I am stocking spares for a building full of Schlage ND locks, how many N523-123 do I order?
One N523-123 covers one ND85 conventional cylinder assembly, since it is sold as a single tailpiece and actuator part with no size or finish choices to pick from. Count the ND85 openings you maintain and order accordingly.
