Sargent SGT-50-40 – Frequently Asked Questions

1) Which Sargent mortise lock functions does the 50-40 hotel cylinder work with?
The 50-40 is built for Sargent 7850, 8250 and 9250 functions. If the lock in your door is one of those hotel functions, the cylinder matches. On any other Sargent mortise function you want a standard cylinder instead, because the guest/emergency split only does something in a lock body that has the hotel deadbolt behavior.
2) Which 50-40 length do I order for a 1-3/8 inch door versus a 1-1/2 inch door?
Order the 50-43 for a 1-3/8 inch door and the 50-44 for a 1-1/2 inch door. Those are the two most commonly ordered, along with the 50-42. The family runs from 1-1/8 inch (29mm) up to 3 inch (76mm) in ten length steps, so thicker doors and heavy trim rings are covered as well.
3) Do I need a particular cam with the Sargent 50-40 hotel cylinder?
Only cam #115, part 13-2045. The 50-40 uses that cam and nothing else, so if you are pulling a cylinder off the shelf with a different cam on it, swap it before install. Sticking to one cam across the property also means your maintenance stock stays simple.
4) Are emergency keys included with the Sargent 50-40 cylinder?
No. Each cylinder ships with 2 nickel silver keys. The emergency key is ordered separately under catalog # 7268 EMK. Budget for those on the front desk side of the job, because without them nobody can override a thrown deadbolt.
5) Will the Sargent 50-40 cylinder key into my existing Sargent master key system?
It can, provided the keyway and pinning match your system. C Series keyways come standard, and you can specify another keyway instead. On the order side the keyway choices are LA (standard), LB, LC, LE, LF, LG, LJ, LK and LL. For an existing 6-pin system, Sargent's key records department will verify the pinning against your key bitting list before the order goes in.
6) Is this a full lock or just the cylinder?
Cylinder only. The 50-40 is a replacement mortise cylinder that drops into an existing Sargent hotel-function mortise lock body. If the lock case itself is worn or the door has never had a hotel function lock, you need a complete 8200 or 9200 series mortise lock, not this part.
7) Is the Sargent hotel cylinder 6-pin or 7-pin?
Six pins is the standard build, with 7-pin capability for the emergency key so the override sits outside the guest and master levels. When ordering you pick 6 Pins or 7 Pins, and you pick Standard Keying, KD (keyed different) or KA (keyed alike) to suit how the rooms are being set up. Guest rooms are normally keyed different; back-of-house openings are where keyed alike earns its place.
8) What finishes does the Sargent 50-40 hotel cylinder come in to match existing room hardware?
Fourteen finishes, which is enough to match most existing lock trim: 03 bright brass and 04 satin brass, 09 bright bronze and 10 satin bronze, three oil-rubbed/dark oxidized bronze variants (10B, 10BE, 10BL), 14 bright nickel and 15 satin nickel, 20D dark statuary bronze, 32 bright stainless and 32D satin stainless, plus BSP black and WSP white suede powder coat. Property managers replacing a handful of cylinders across a floor should match the existing lever trim code rather than guessing from the photo.
9) Can I use the Sargent 50-40 on apartments or dorms, not just hotels?
Yes, and it is a common move. Any opening where a resident needs to throw a deadbolt for privacy but management needs an override works the same way: student housing, extended stay, senior living, healthcare rooms. The requirement is the lock body, not the building type, so the door has to already carry a 7850, 8250 or 9250 function mortise lock.
