Sargent 13-0845 – Frequently Asked Questions

1) What exactly is the Sargent 13-0845 part, and what does it do inside the lock?
The 13-0845 is a cylinder tailpiece, the small drive piece that links the key cylinder to the knob assembly so turning the key actuates the lock. It is not a cylinder, not a knob, and it comes with no key or core. Sargent lists it for S and N knob designs in the 50 function. If the key turns freely without retracting the latch, a worn or broken tailpiece is the usual cause and this is the replacement piece.
2) Will the Sargent 13-0845 tailpiece work with any Sargent knob lock?
No. It is built for S and N style knobs in 50 function assemblies only. Other Sargent knob designs and other functions use different tailpiece lengths and drive shapes, so pull the knob and confirm you have an S or N knob on a 50 function lock before ordering this one. Fitting the wrong tailpiece either binds or fails to pick up the retractor.
3) My Sargent exit device needs a rim cylinder, not a knob tailpiece. What should I order?
The 13-0845 tailpiece serves S and N knob assemblies in 50 function locks and has no application in a rim device. For a rim cylinder, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Match the cam orientation or tailpiece length to what the device chassis requires.
4) If the cylinder itself is bad and not just the tailpiece, what Sargent knob or lever cylinder can be used?
The Sargent 13-0845 is only the cylinder tailpiece, the part that transmits motion from the cylinder to an S or N knob in a 50 function assembly. If the cylinder body itself is worn, the Kaba Ilco 1579 is a knob and lever cylinder built for Sargent applications, so it addresses the cylinder rather than the drive part. Replace the tailpiece when the keying and plug still work but knob engagement has failed; replace the cylinder when the plug or pins are the problem.
5) The lock in my door is a mortise lock, not a knob set. Is the 13-0845 the right part?
No. The 13-0845 tailpiece is specific to Sargent S and N knobs in the 50 function. A mortise lock takes a mortise cylinder with a cam: the Corbin Russwin 1000 Grade 1 mortise cylinder comes in 1-1/2 inch length with an A02 straight cam, the Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway. Cam style has to match the mortise lock body.
6) Does a rim or mortise cylinder tailpiece like the Schlage 20-021 substitute for the Sargent 13-0845?
No. The Schlage 20-021 and 20-022 are complete rim cylinders with vertical and horizontal tailpiece cams for exit device applications, and the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Those are rim products for a different prep entirely. The 13-0845 is a loose tailpiece for a Sargent S or N knob in 50 function and does not interchange with rim cylinder hardware.
7) Do I get a key or a core with the Sargent 13-0845?
No keys and no core. It is a replacement part only, so the existing cylinder and keying stay as they are. That also means installing it does not disturb a master key system. If you need a keyed cylinder as well, order that separately, such as a Kaba Ilco 1579 cylinder made for Sargent.
8) Can a maintenance tech swap this tailpiece in the field, or does it need a locksmith?
It is a drop-in swap. Remove the knob, back out the old tailpiece from the cylinder, fit the 13-0845 and reassemble, which keeps downtime short on an occupied door. No drilling or door prep changes are involved since the part matches the original factory component. The only judgment call is confirming the lock is a 50 function with an S or N knob.
9) We are standardizing a building on interchangeable cores. Does the 13-0845 fit that plan?
The 13-0845 is a mechanical drive tailpiece for Sargent S and N knobs in 50 function locks, so it keeps an existing keyed assembly working rather than changing the keying platform. For a core-based program, the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill resistant 7-pin brass interchangeable core in the 150 Series, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those change how the opening is keyed; the tailpiece does not.
10) Is the Sargent 13-0845 a genuine factory part or an aftermarket copy?
It is an authentic Sargent lock part, built to the same standard as the component installed at the factory, and intended as a drop-in for a worn or damaged tailpiece during service.
11) Is this tailpiece rated for commercial door traffic or is it a residential part?
Commercial. Sargent classes the 13-0845 as a commercial-grade replacement part for mechanical lock assemblies, and it is used in office buildings, schools, hospitals, retail, government facilities, warehouses and multi-tenant residential properties.
12) Does a deadbolt cylinder work in place of the Sargent 13-0845?
It does not. The 13-0845 drives an S or N knob in a 50 function lock and has no deadbolt application. For deadbolts, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Those are keyed cylinders for bolt-driven hardware, a different mechanism from a knob tailpiece.
13) I need a non-keyed part for a knob that does not lock. Is the 13-0845 that part?
The 13-0845 is a working tailpiece that transmits cylinder motion to an S or N knob, so it belongs in a keyed 50 function assembly. Where no keying is wanted, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the cylinder opening without operating anything. Choose the tailpiece for a functioning lock and the dummy cylinder for a fixed or inactive trim.
