Sargent SGT-41 LA 3 – Frequently Asked Questions

1) What length Sargent 40 Series mortise cylinder do I need for my door?
Sargent 40 Series mortise cylinders are ordered by length, and the choices are 1-1/8, 1-1/4, 1-3/8, 1-1/2 and 1-3/4 inches. Length is set by how far the cylinder has to reach from the outside face of the door through the trim or escutcheon to the lock case, not by the door thickness alone. On a standard 1-3/4 inch door with a mortise lock and no thick trim, 1-1/8 inch is the usual starting point; every layer stacked on the face (an escutcheon, a wrap, a thick rose) pushes you up the range. Measure from the finished outside face to the cam pocket and pick the size that leaves the cylinder face flush. Collars and spacers are available separately if you land between sizes.
2) Will a Sargent 40 mortise cylinder fit a standard mortise lock prep?
The 40 Series cylinder is a 1-5/32 inch (29mm) diameter threaded mortise cylinder, which is the standard mortise cylinder thread size, so it threads into a conventional mortise lock case prep. What you still have to match is the cam: it ships with the standard Sargent offset cam 13-0664, and cams 101, 105, 106, 112, 113 and 115 are selectable at order. The cam is what actually engages the lock mechanism, so getting the diameter right and the cam wrong still leaves you with a cylinder that turns and does nothing.
3) Can I get a Sargent 40 cylinder keyed alike to the rest of my building?
Yes. Keying is specified at order as Standard Keying, KD (keyed different), or KA (keyed alike), so a property manager standardizing a floor or a whole building can put every door on one key. The keyway also has to match what is already in service: LA is the standard keyway, with LB, LC, LE, LF, LG, LJ, LK and LL also available. Pull a key from an existing door and confirm the keyway letter before ordering, because a keyed-alike order in the wrong keyway will not enter the lock.
4) Should I order the 6-pin or 7-pin Sargent 40 cylinder?
Six pins is the standard build and is what matches most existing Sargent conventional key systems. Seven pins buys additional key differs and deeper masterkeying depth, which matters on a large facility running multiple master levels. The constraint is physical: the 7-pin option requires a size 42 minimum, so a short cylinder cannot be built 7-pin. Match whatever your existing system runs, since mixing pin counts inside one masterkey system is not something you can do at the door.
5) What does a Sargent 40 mortise cylinder come with if I order it plain?
Ordered without a keying spec, the cylinder is supplied 1-bitted with two nickel silver keys and the standard Sargent offset cam 13-0664. One-bitted means it is not cut to a working key, it is a construction bitting a locksmith re-pins to your system. If you want it usable straight out of the box on your existing key, order it keyed alike or keyed different in your keyway instead of taking the 1-bitted default.
6) Is a mortise cylinder the right part, or do I need a rim cylinder?
A mortise cylinder threads into the lock case and drives the lock through a cam, which is what the 40 Series is: a 1-5/32 inch diameter threaded body with a selectable cam. That is the part for a mortise lockset. If the lock on your door is a rim exit device mounted on the face of the door, that takes a rim cylinder with a tailpiece instead, and this will not work in it. If the door has a cylindrical lever or knob lock, neither one applies. Look at how the existing cylinder comes out: if it unscrews from the edge-side lock case, you want a mortise cylinder.
7) Can I replace just the cylinder without changing the whole Sargent mortise lock?
Yes, that is exactly what the 40 Series is for. It is a replacement cylinder, so a lost-key or rekey situation on an existing Sargent mortise lock is solved by unthreading the old cylinder and threading in a new one of the same length with a matching cam. The lock case, trim and door prep stay untouched. Order it keyed alike to the other doors if you are bringing the opening back onto the building key.
8) What finish do I order to match the rest of my Sargent hardware?
Finishes run 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 15 satin nickel, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, BSP black suede powder coat and WSP white suede powder coat. For an architectural match the cylinder face should carry the same code as the lock trim beside it, so read the finish code off the existing hardware rather than matching by eye. 32D and 10B are the two that turn up most on commercial openings.
9) Is the Sargent 40 cylinder solid brass, and will it hold up on an exterior door?
The body is solid brass, with cap options in brass, bronze or stainless steel. Brass resists corrosion, which is why it holds up on exterior openings and in coastal or wash-down environments better than a plated pot-metal cylinder. This is a commercial-duty part, used on office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and municipal buildings.
