Schlage N123-034 626 – Frequently Asked Questions

1) What exactly is the Schlage N123-034 part, and what does it do on an ND40 lock?
The N123-034 is the emergency button and plunger assembly for the exterior lever side of a Schlage ND40 lockset. It is the small button in the outside trim that a plunger or emergency key tool pushes to release the lock for emergency access. When that button sticks, breaks off, or the plunger no longer actuates, the lever itself is usually fine, and this assembly restores the function.
2) I manage a building with dozens of ND40 privacy locks. Can I stock this button as a repair part instead of replacing whole locksets?
That is what it is for. The N123-034 is a genuine Schlage replacement part, so a broken or seized emergency button on an ND40 can be fixed at the trim instead of pulling and rekeying a whole lockset. Buy it in the finish that matches your standard so one shelf stock covers every door of that finish.
3) Which finishes does the Schlage N123-034 emergency button come in?
Nine finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. Order the button in the same Schlage finish code as the lever it sits in, since the button face is visible on the outside trim and a mismatched code will read as an off-color dot on the lever.
4) Does the N123-034 include the lever or the lock chassis?
No. This is the button and plunger only, the emergency release component that mounts in the ND40 outside lever. If the lever itself is bent, the chassis is worn, or the inside privacy turn is broken, those are separate ND-series parts.
5) Do I need to modify the door or drill anything to install this emergency button?
No door work. It is a direct replacement for the ND40 exterior lever assembly, so it drops into the existing trim with no modification. The work happens at the lever, not the door prep.
6) Is the N123-034 a commercial-duty part or a residential one?
Commercial. It belongs to Schlage's ND series, the heavy-duty cylindrical line used in schools, hospitals, offices and government buildings, and the part is classified for commercial use rather than residential.
