Sargent SGT-50-6043 3 – Frequently Asked Questions

1) Will a Sargent 50-63-40 LFIC cylinder work on a Sargent 8200 mortise lock in a hotel function?
Yes, if the lock is a Sargent hotel function. The 50-63-40 large format interchangeable core mortise cylinder ships with the 115 cam, which is the cam for Sargent 7850, 8250 and 9250 hotel functions. Put that same cylinder on a standard office or classroom mortise lock and the cam is wrong, so order the cylinder that matches the function you actually have on the door.
2) What is the difference between the Cylinder and Body Only options on the Sargent 50-63-40?
Body Only is the mortise housing with the 115 cam and no core in it, for a property that already has LFIC cores on hand or is pulling a core from stock keyed into an existing system. The Cylinder option is the complete assembly with the 6-pin core in place and change keys included. If you are a locksmith building the keying yourself from your own cores, take the body; if this is a one-off replacement on a hotel door, take the cylinder.
3) Do I need a control key to swap a Sargent LFIC hotel core, and does it come with the cylinder?
A control key is required and it is not included. The 6255 CTL control key releases the locking cam so the core lifts out, and it has to be ordered separately. Without it the core will not come out of the housing. Budget one control key per keying system, not one per door, and keep it off the housekeeping ring.
4) Can I rekey hotel room doors without pulling the mortise lock out of the door?
That is the whole point of the interchangeable core. With the control key the core comes straight out of the mortise housing while the lock stays in the door, so a guest room turns over in under a minute instead of a lock removal and a repin. For a property manager cycling rooms after a lost key, it is the difference between a service call and a housekeeping cart stop.
5) What do I have to specify when ordering a Sargent 50-63-40 hotel mortise cylinder?
Three things: finish, whether you want the complete cylinder or the body only, and the keying. Keying is a required choice between standard keying, KD keyed different, or KA keyed alike. Hotel guest rooms are almost always KD so every room has its own change key; KA is for back-of-house groups like storage or mechanical rooms that share one key.
6) Is the Sargent 50-63-40 a small format or large format interchangeable core?
Large format. LFIC cores are the bigger Sargent figure-eight core, not the SFIC seven-pin format, and the two do not interchange in the same housing. If your property is already running SFIC cores, these will not drop into that hardware, and mixing the two formats on one site means two control keys and two pinning kits.
7) Can Sargent LFIC hotel cylinders be put on a master key and grand master key system?
Yes. The 6-pin core is built to drop into master or grand-master keyed systems, which is the normal setup for a hotel: guest change key, floor or section master, house master above that. Give the keying schedule when you order so the cores arrive pinned to the system rather than needing a repin on site.
8) Can a locksmith key these Sargent cores in the field instead of ordering them keyed?
Yes, order them 1 bitted. Those come with 2 key blanks and pins and springs already loaded in chambers 3 and 4, so the shop pins the rest to the system without waiting on a factory keying order. Useful for a contractor stocking cores ahead of a floor renovation where the final keying schedule is not settled.
9) Is this Sargent LFIC cylinder only good for hotel locks, or will it work on exit devices and bored locks too?
The core itself is Sargent large format interchangeable core and works across the Sargent line, including exit devices, mortise locks, bored locks and padlocks, so one keying system can cover the guest rooms, the stair doors and the padlocks in the yard. The 50-63-40 housing is the piece that is specific: it is a mortise cylinder with the 115 hotel cam. For an exit device or a bored lock you keep the same cores but order the housing that suits that hardware.
10) What finishes does the Sargent 50-63-40 LFIC hotel cylinder come in?
Twelve: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 15 satin nickel, 20D dark statuary bronze, 32 bright stainless, 32D satin stainless, and BSP black suede powder coat. Every one of those is offered as both a complete cylinder and a body only, so a partial floor replacement can match the trim already on the doors.
11) Is the Sargent 50-63-40 cylinder rated for commercial use or is it a residential part?
Commercial. It is part of Sargent's 40 Series conventional key system, built for the traffic a hotel corridor or a dorm floor puts on a lock. The buyer for it is typically a hospitality property, a multi-tenant residential building, a dorm, a healthcare facility or a government building standardizing keying across a site.
