Sargent SGT-11-6342 LA 3 – Frequently Asked Questions

1) Which cam do I need to order with a Sargent 11-63-40 mortise cylinder?
Cam choice is a required selection on the 11-63-40, not an accessory you add later, and it has to match the lock the cylinder is going into. The options are Standard, 101, 105, 106, 112 and 113. The cam is what actually drives the lock mechanism, so a cylinder with the wrong cam threads in fine and does nothing. If you are replacing an existing Sargent mortise cylinder, pull it and match the cam on the back before ordering.
2) Will a Sargent XC large format core drop into my existing 6300 cylinders?
The XC 11-6340 large format cylinder uses the same pins and principles as the 6300 core series, so it integrates with an existing Sargent 6300-based key system rather than forcing a separate one. The cylinder body is 1-5/32 inch (29mm) solid brass, which is the large format interchangeable core size, so it takes a large format core and not a small format one. Keyway still has to match your system: pick from LA, LB, LC, LE, LF, LG, LJ, LK or LL.
3) How do I order Sargent 11-63-40 cylinders keyed alike for a building?
Keying is a required choice on the 11-63-40 and there are three paths: Standard Keying, KD (keyed different, every cylinder its own key), or KA (keyed alike, one key operates the whole group you order together). For a property manager standardizing a floor or a building, KA on a single order is how you get one key across those openings. For tenant doors where each unit needs its own key, KD is the call. Keyway has to be consistent across the group too, so specify the same keyway (LA is standard) on everything you want working together.
4) What is the point of an interchangeable core cylinder instead of a conventional one?
With the 11-63-40, the core pulls out with a control key and a new core drops in while the cylinder stays in the door. You rekey an opening in seconds, no lock disassembly, no pinning on site. That is the difference from a conventional mortise cylinder, where rekeying means taking the cylinder out and repinning it. For MRO and institutional work with staff turnover, or a property manager turning units, that is the reason to spec IC in the first place. The tradeoff is that you are buying into the large format core platform, so cores, control keys and keyways all have to stay on the same system.
5) Does the Sargent 11-63-40 mortise cylinder come with a core and keys?
The 11-63-40 is the mortise cylinder housing in the XC large format interchangeable core system. Cams are a required selection with it, and keying is specified at order. Collars and spacers, which you may need to set the cylinder flush with the trim on a thicker door or heavier escutcheon, are sold separately and are not part of the cylinder. Plan the order around cylinder, cam, keyway and keying together, since all four have to agree with the lock and the key system already in the building.
6) Can I get Sargent mortise cylinders to match dark bronze and stainless door hardware?
Thirteen finishes are offered on the 11-63-40, which covers most commercial trim you will run into: 03 bright brass and 04 satin brass, 09 bright bronze and 10 satin bronze, four dark oxidized satin bronze variants (10B oil rubbed, 10BE, 10BL clear coated, and 20D dark statuary bronze lacquered), 15 satin nickel, 32 bright stainless and 32D satin stainless, plus BSP black and WSP white suede powder coat. For matching existing openings, 32D and 10B are the two that come up most in commercial buildings. Cap material is offered in brass, bronze and stainless steel, which matters outdoors or in coastal and pool environments where stainless holds up better than plated brass.
7) Is the Sargent 11-63-40 cylinder suitable for a school or hospital, or is it a residential part?
It is a commercial cylinder, built for institutional key control: solid brass body, large format interchangeable core, and the Sargent XC key system behind it. Typical use is commercial office, education, healthcare, retail, industrial, multi-tenant residential and government buildings. The reason it fits those facilities is the core swap, you rekey a wing after a staff change without pulling locks apart, and you can standardize the whole facility on one keyway and one core format.
