Sargent 10-0548 26D – Frequently Asked Questions

1) What is the Sargent 10-0548 P Design cylinder prep actually used for?
The Sargent 10-0548 is a P Design cylinder preparation component that lets a Sargent lock accept a Sargent Removable Core cylinder. It is the prep piece, not the core or the key cylinder itself, so you still need the removable core to complete the opening. Once in place, the core can be pulled and swapped for re-keying without taking the lock body apart.
2) Will the Sargent 10-0548 work on my 7-Line mortise lock, or is it 10-Line only?
Both. The 10-0548 P Design prep is made for Sargent 7-Line and 10-Line lock series, so it covers a large share of Sargent's commercial mechanical lock platform. If your hardware is another Sargent line, it is not the part for that opening.
3) I need a replacement cylinder for a Sargent lock, not a prep part. What should I be looking at?
If the lock body is fine and you only need the keyed cylinder for a Sargent knob or lever, the Kaba Ilco 1579 Series knob and lever cylinder is built for Sargent locks and is the part to look at instead. The 10-0548 is the P Design prep that receives a Sargent Removable Core, so it solves a different problem: it prepares the lock to take a core rather than supplying the keyed plug.
4) Can I put a BEST interchangeable core into the Sargent 10-0548 prep?
No. The 10-0548 is prepped for Sargent Removable Core cylinders. BEST small format cores such as the 1C Series 5-pin core or the 1CB 150 Series core are a different core geometry and belong in BEST-prepped housings. If your facility is standardized on BEST, source a BEST-prepped housing rather than adapting this one.
5) Is the Sargent 10-0548 a cylinder I can key, or do I still need a core?
The 10-0548 is a P Design cylinder prep component for Sargent Removable Core cylinders in the 7-Line and 10-Line lock series - it is the prepped housing side that accepts the core, not a keyed cylinder with pins and keys. If you need an actual keyable interchangeable core, the BEST 1C Series standard 5-pin cylinder core and the BEST Peaks 1CB 150 Series interchangeable core cylinder are cores in their own right, and the Schlage 20-057-C is a full size interchangeable core in a C keyway with a 643E Aged Bronze finish.
6) The opening takes a mortise cylinder, not a removable core prep. What are my options?
The Sargent 10-0548 is a prep component for Removable Core cylinders in the 7-Line and 10-Line series and is not a mortise cylinder. For a mortise body, the Corbin Russwin 1000 Grade 1 Series mortise cylinder measures 1-1/2 inches with an A02 straight cam, the Corbin Russwin 1070 Grade 1 Series 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 a Schlage C keyway. Adams Rite also lists the 4036 mortise cylinder, Grade 1, with a 1/2 inch minimum door thickness.
7) Is the 10-0548 a genuine Sargent part or an aftermarket copy?
It is a genuine Sargent OEM replacement part, built to restore original factory fit and function in Sargent lock systems. For facilities standardized on Sargent key control, that matters: an off-brand prep can hold the core at the wrong depth and cause the key to bind.
8) What finishes does the Sargent 10-0548 cylinder prep come in so it matches my other doors?
Thirteen finishes, which is usually enough to match whatever is already hanging in the building: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze lacquered, 26 bright chrome, 26D satin chrome, plus BSP black suede and WSP white suede powder coat. Order the same finish code as the lock trim it sits in, not just the same color name.
9) Why choose a removable core setup instead of a fixed keyed cylinder?
Removable core is about key control and turnaround. With the 10-0548 P Design prep, a locksmith pulls the core with a control key and drops in a new one, so re-keying after a tenant turnover or a lost master takes minutes and no disassembly of the lock body. A fixed cylinder like the Corbin Russwin 1000 Series mortise cylinder has to be pulled and re-pinned or replaced outright. On a handful of doors that is fine; across a campus or a hotel floor, removable core is what makes the key system manageable.
10) If the door uses a rim device instead of a Sargent 7/10-Line lock, what cylinder goes with it?
The Sargent 10-0548 preps a Removable Core cylinder into 7-Line and 10-Line lock bodies, which is a different mounting than a rim device. Rim cylinders in the set include the Schlage 20-021 6-pin with a vertical tailpiece cam and the 20-022 6-pin with a horizontal tailpiece cam, the Schlage 20-057 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece.
11) We want key control and drill resistance on a high-security wing. Does the 10-0548 provide that by itself?
The 10-0548 is the P Design prep that lets a Sargent Removable Core cylinder drop in and out for fast re-keying and master key changes without taking the lock apart, but the security level comes from the core you install in it. Where drill resistance and patented key control are the requirement, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin brass, 150 Series.
12) Is a cylinder pull like the Adams Rite 4024 or 4025 an alternative to the Sargent 10-0548?
No. The 10-0548 is a Sargent cylinder prep part for Removable Core cylinders on 7-Line and 10-Line locks. The Adams Rite 4024 cylinder pull uses trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both designed for the Adams Rite MS1847 deadlock/deadlatch, while the 4026 five pin tumbler pull is for the Adams Rite 5017 wood door deadlock/deadlatch. Those are pull-and-cylinder assemblies for narrow stile and wood door deadlocks, a different opening entirely.
13) Is this a residential-grade part or is it meant for commercial buildings?
Commercial. The 10-0548 is catalogued for commercial door hardware use, and the applications it is built around are master-keyed office buildings, schools, hospitals, government buildings, multi-tenant properties and hotels running removable core systems.
14) Will a deadbolt cylinder work in place of the Sargent 10-0548?
No. The 10-0548 is a Removable Core cylinder prep for Sargent 7-Line and 10-Line lock bodies. Deadbolt cylinders are a separate application: the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the 1599 Series is a key-in-knob replacement cylinder, both listed with a deadbolt product function, and Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
