Sargent 10-0549 26D – Frequently Asked Questions

1) Does the Sargent 10-0549 come with an interchangeable core, or do I order the core separately?
The 10-0549 is prepared to accept an interchangeable core, which means the core itself is a separate item keyed to your system. Order it as the housing/part and pair it with an IC core in your existing Sargent keyway so the new part drops into your key control scheme.
2) If my lock is not a Sargent, what interchangeable core cylinder should I look at instead?
Skip the 10-0549, since it is built to the Sargent 72-Line and 7/10-Line pattern. For a BEST-style small format IC system, the BEST 1CB 150 Series interchangeable core or the 1CDF drill resistant 7-pin core are the direct picks. If you are on Schlage, the 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam covers rim exit device applications. For a Sargent knob or lever cylinder from an aftermarket source, Kaba Ilco's 1579 Series is made for Sargent.
3) What is the closest alternative to the Sargent 10-0549 for rekeying a Sargent knob or lever without buying a Sargent part?
The Kaba Ilco 1579 Series knob and lever cylinder is built for Sargent locks, so it is the aftermarket route for a Sargent key-in-knob or key-in-lever opening. The difference in approach matters: the Sargent 10-0549 is a P Design commercial replacement part prepared to accept an interchangeable core, so cores can be swapped for rekeying, while the 1579 is a cylinder unit rather than an IC-prepped part. If your key control system is built on interchangeable cores, stay with the 10-0549.
4) Is there an interchangeable core cylinder option other than the Sargent 10-0549 for a facility standardizing key control?
Yes. BEST offers the 1CB 150 Series interchangeable core cylinder and the 1CDF drill resistant patented 7-pin brass 150 Series core, and Schlage offers the 20-057-C full size interchangeable core in C keyway. Those commit the opening to BEST or Schlage keyways and core geometry. The Sargent 10-0549 is the part to use when the installed hardware is Sargent 72-Line or 7/10-Line and the existing Sargent IC key system is being retained.
5) I need to rekey a Sargent lock without replacing the whole lockset. Does this part do that?
That is what it is for. The 10-0549 restores the IC cylinder portion of a 72-Line or 7/10-Line lock, so the lock body, trim and door prep all stay put. Once the part is in, rekeying is a core swap rather than a hardware change.
6) Is the Sargent 10-0549 a mortise cylinder like a Corbin Russwin 1000?
No. The 10-0549 is an interchangeable-core-prepped P Design part specific to Sargent 72-Line and 7/10-Line locks, not a standard threaded mortise cylinder. If you need a mortise cylinder with a cam, that is a different part: the Corbin Russwin 1000 Grade 1 at 1-1/2 inch with an A02 straight cam, or the 1070 at 1-1/4 inch with an A01 cloverleaf cam, are mortise housings. Match the cam to your lock body before ordering either.
7) Why does the P Design designation matter when ordering the Sargent 10-0549?
P Design is the profile that matches specific Sargent lock trim and function requirements, so it governs whether the part seats correctly in your lockset. Confirm the existing lock is a 72-Line or 7/10-Line carrying the P design before ordering, because a different design profile in the same series will not be an exchange.
8) I need the cylinder to match other finishes in the building. Does the Sargent 10-0549 cover more finishes than the comparable cylinders?
The Sargent 10-0549 is offered in thirteen finishes including 03 Bright Brass clear coated, 04 Satin Brass, 09 Bright Bronze, 10 Satin Bronze, 10B Dark Oxidized Satin Bronze oil rubbed, 14 Bright Nickel, 15 Satin Nickel, 20D Dark Statuary Bronze, 26 Bright Chromium, 26D Satin Chromium, plus Black and White Suede powder coat. Among comparable interchangeable core parts, the Schlage 20-057-C is specified in 643E Aged Bronze, so finish matching across a mixed-hardware building is the deciding factor.
9) Will a rim cylinder work in place of the Sargent 10-0549?
No. Rim cylinders such as the Schlage 20-021 with vertical tailpiece cam, the Schlage 20-022 with horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim housing with 1-7/8 inch tailpiece mount through the door face and drive a rim device tailpiece. The Sargent 10-0549 is a P Design cylinder replacement part for 72-Line and 7/10-Line locks and is not a rim housing, so the two are not interchangeable.
10) If the Sargent hardware is being replaced on a deadbolt rather than a knob, is the 10-0549 still the right part?
No. The 10-0549 is a P Design replacement part for Sargent 72-Line and 7/10-Line locks. For deadbolt cylinder work, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the 1539 Series is a key-in-knob/lever universal cylinder, both listed for deadbolt function, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. Match the part to the lock body you actually have in the door.
11) What looks like a substitute for the Sargent 10-0549 but is not?
Cylinder pulls and dummy cylinders get confused with cylinder replacement parts. The Adams Rite 4025 and 4024 are cylinder pulls for the MS1847 deadlock, the 4026 is a five-pin cylinder pull for the 5017 wood door deadlock, and the BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter that provides no keyed function. The Sargent 10-0549 is a keyed-cylinder replacement part prepared for an interchangeable core in Sargent 72-Line and 7/10-Line locks.
12) Is there a simpler non-IC cylinder option if a facility does not run interchangeable cores?
Yes. The Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, the Falcon A23161-05 G is a key-in-lever cylinder for RU/T Series in 6-pin G keyway supplied keyed different with two cut keys, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. Those are fixed-cylinder parts keyed at the cylinder. The Sargent 10-0549 is prepared to accept an interchangeable core so cores can be swapped for rekeying.
13) Does the Sargent 10-0549 work for a residential handleset or Emtek deadbolt?
No. The 10-0549 is specified as commercial and is a P Design part for Sargent 72-Line and 7/10-Line locks. For handleset and residential deadbolt cylinders, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1075127 is a 5-pin rim lazy motion single cylinder for handlesets and deadbolts, and Emtek lists the CY4 cylinder as a part.
14) Our building runs Schlage L9000 mortise locks but the Sargent doors need parts too. What pairs with each?
Two different parts. The Corbin Russwin 1080 Grade 1 is a 1-1/2 inch LFIC 6-pin mortise cylinder called out for Schlage L9000 mortise locks with an A01 Schlage L cam. The Sargent 10-0549 is the P Design replacement part for Sargent 72-Line and 7/10-Line locks and is prepared to accept an interchangeable core. Order by the lock family on each door rather than trying to standardize on one cylinder part.
15) Can a BEST 1C core be dropped into the Sargent 10-0549?
The BEST 1C Series is a standard 5-pin cylinder core from the Standard and Premium Cores line and belongs to the BEST core system. The Sargent 10-0549 is a P Design part prepared to accept an interchangeable core within the Sargent 72-Line and 7/10-Line ecosystem, so plan on a Sargent core for it and keep BEST cores to BEST housings such as the 1CB 150 Series.
16) Is the Sargent 10-0549 a commercial part or residential?
Commercial. It is catalogued as a commercial-grade OEM replacement part and is used in offices, schools, healthcare, government buildings, multi-tenant residential, warehouses and retail where Sargent IC key control is already in place.
