Sargent 13-0846 – Frequently Asked Questions
1) What exactly is the Sargent 13-0846 and what does it do inside the lock?
The 13-0846 is a cylinder tailpiece, the flat metal blade that carries rotation from the key cylinder into the lock mechanism. It is not a cylinder, not a knob, and it does not come keyed. Sargent calls it out for D Knob, 50 function mechanical lock configurations, and it is sold as a replacement part for commercial door hardware.
2) Will the Sargent 13-0846 tailpiece work in a lock that isn't a D knob, 50 function?
No. Sargent builds tailpieces to match the specific knob style and lock function, and the 13-0846 is called out for D Knob, 50 function assemblies. Tailpiece length and blade geometry change with the function, so a 50 function D knob part put into a different function or a lever trim will either not engage or will bind. Identify the lock function stamped on the chassis before ordering.
3) My Sargent knob turns but the key won't throw the latch. Is the tailpiece the part that failed?
That is the classic symptom of a worn or sheared tailpiece. The tailpiece is the interface between the cylinder and the lock mechanism, transmitting rotational force to the locking hardware. When it wears round or snaps, the key rotates freely with no action at the latch while the knob itself still works. On a Sargent D knob 50 function lock, the 13-0846 is the drop-in service part for that repair.
4) If the Sargent knob cylinder itself is bad and not just the tailpiece, what replaces it?
The Sargent 13-0846 is a cylinder tailpiece only - the part that carries rotation from the cylinder into the lock mechanism on D knob, 50 function mechanical locks. If the cylinder plug or housing is the failed component, the Kaba Ilco 1579 is a knob and lever cylinder built for Sargent locks. That is a whole replacement cylinder rather than the drive piece, so it addresses a worn or picked cylinder rather than a stripped or broken tailpiece.
5) The lock on that door is a mortise, not a knob - is the 13-0846 still the right part?
No. The 13-0846 serves D knob, 50 function Sargent mechanical locks. Mortise bodies take a threaded mortise cylinder driven by a cam instead of a tailpiece - for example the Corbin Russwin 1000 Grade 1 series 1-1/2 inch mortise cylinder with A02 straight cam, or the 1070 Grade 1 series 1-1/4 inch 6-pin mortise housing with A01 cloverleaf cam. Cam style has to match the mortise lock body.
6) Does the Sargent 13-0846 include a cylinder or keys?
No cylinder and no keys. The 13-0846 is the tailpiece only, ordered as a single part. If the cylinder itself is the problem rather than the tailpiece, you need a knob/lever cylinder instead, for example the Kaba Ilco 1579 Series knob and lever cylinder made for Sargent locks.
7) Is there any variation of the Sargent 13-0846 I need to specify, like finish or length?
There is one configuration, ordered as part number 13-0846. Nothing to pick on finish, handing, or length. Tailpieces are internal, so finish is irrelevant to the part.
8) Should I replace just the tailpiece or swap the whole cylinder on a Sargent knob lock?
If the key turns smoothly and the pins feel normal but nothing happens at the latch, the tailpiece is the failed link and the 13-0846 fixes it at a fraction of the labor. If the key is sticking, binding, or the keying has to change for a rekey or a lost master, replace the cylinder instead. Retrofit knob and lever cylinders exist for Sargent, such as the Kaba Ilco 1579 Series, and universal key-in-knob replacements like the Ilco 1539 Series cover mixed fleets.
9) Will a rim cylinder with a tailpiece work in place of the Sargent 13-0846?
No. Rim cylinders such as the Schlage 20-021 with vertical tailpiece cam and the Schlage 20-022 with horizontal tailpiece cam come with their own tailpiece, but they mount through a door for rim exit devices, not into a Sargent D knob lock. The 13-0846 is a loose tailpiece for a D knob 50 function Sargent mechanical lock and does not interchange with rim cylinder tailpieces.
10) Is there a generic key-in-knob cylinder I can use instead of a Sargent-specific part?
For key-in-knob service where the brand does not have to match, Kaba Ilco offers the 1539 key-in-knob / lever universal cylinder and the 1599 key-in-knob replacement cylinder. Those are aftermarket cylinders that replace the keyed unit. The Sargent 13-0846 is a different kind of part - the tailpiece that links a cylinder to a D knob 50 function Sargent lock body - so it is used when the existing cylinder is being kept.
11) We want to move this opening to interchangeable core instead of repairing the knob - what do we order?
Converting to interchangeable core means replacing the cylinder, not repairing the drive. BEST offers the 1C 5-pin standard cylinder core and the 1CB 150 Series interchangeable core cylinder for small format IC housings, and Schlage lists the 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam for full size IC on a rim application. The Sargent 13-0846 tailpiece keeps the existing conventional D knob 50 function lock in service instead.
12) Our doors are aluminum storefront - is this the tailpiece for those?
No. The 13-0846 is a Sargent part for D knob 50 function commercial mechanical locks. Narrow stile aluminum storefront typically runs Adams Rite hardware: the 4036 Grade 1 mortise cylinder suits a 1/2 inch minimum door thickness, and the 4024 and 4025 cylinder pulls are built for the MS1847 deadlock and deadlatch. For a wood door version, Adams Rite lists the 4026 five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch.
13) Is the Sargent 13-0846 suitable for a high traffic building, or is it a light duty part?
It is a commercial part. Sargent lists the 13-0846 under commercial door hardware, and the typical applications are office buildings, schools, hospitals, retail, warehouses, multi-tenant residential, and government facilities. For a property manager keeping spares on hand, it is a sensible stock item on any building standardized on Sargent D knob 50 function locks.
14) What about a deadbolt on the same suite door - does this tailpiece cover it?
It does not. The Sargent 13-0846 is dedicated to D knob 50 function lock assemblies. For keyed deadbolt service, Kaba Ilco lists the 1549 key-in-deadbolt cylinder, and Medeco lists the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
15) We want higher key control on these knob openings rather than just fixing the tailpiece - what are the options?
The Sargent 13-0846 tailpiece restores mechanical function but does not change keying security. For upgraded key control, BEST lists the 1CDF drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. Medeco lists the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Those are cylinder replacements, so the knob or lock body has to accept the cylinder format.
16) Is a Falcon key-in-lever cylinder an alternative for a Sargent knob lock?
They are not interchangeable. The Falcon A23161-05 G is a key-in-lever cylinder from the RU/T series with a 6-pin G keyway, keyed different and supplied with two cut keys - it fits Falcon lever locks. The Sargent 13-0846 tailpiece is matched to Sargent D knob 50 function lock assemblies, so mixing the two will not produce correct cylinder-to-mechanism engagement.
