Schlage A501-941 – Frequently Asked Questions
1) What exactly is the Schlage A501-941 and what part of the lock does it hold?
The A501-941 is a retainer, a small genuine Schlage service part that holds the full size interchangeable core cylinder in place inside the lock body. It is not a cylinder or a core itself, so it does not key anything and it does not come with a key. You order it when the core will not seat or stay retained in an existing A Series or H Series FSIC assembly.
2) If the cylinder itself is worn rather than just the retainer, what interchangeable core can replace it?
The Schlage A501-941 is a replacement retainer, a small component that holds a full size interchangeable core cylinder in an A Series or H Series lock body - it does not include a core or any pins. If the core itself is the problem, a full interchangeable core is the part to buy: the BEST 1C Series standard 5-pin cylinder core, the BEST 1CB Peaks 150 Series interchangeable core, or the BEST 1CDF drill resistant patented 7-pin brass 150 Series core in the same 150 Series family. Those are complete keyed cores; the A501-941 is only the retention hardware.
3) Will the Schlage A501-941 retainer work in a mortise lock?
No. The A501-941 is a retainer for Schlage A Series and H Series full size interchangeable core applications, which are cylindrical knob and lever locks. A mortise lock takes a threaded mortise cylinder instead - for example the Corbin Russwin 1000 Grade 1 Series mortise cylinder in 1-1/2 inch length with an A02 straight cam, the CR1070 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, or the Corbin Russwin 1080 Series 1-1/2 inch LFIC mortise cylinder built for Schlage L9000 mortise locks with a Schlage L cam.
4) Can I repair a Schlage FSIC lockset with this part instead of replacing the whole lock?
That is what it is for. The retainer is sold as a direct replacement component so a locksmith or maintenance tech can restore an existing A or H Series FSIC cylinder assembly in the field rather than pulling and replacing the entire lockset. Useful when a facility is standardized on Schlage hardware and you want to keep the keyway and the master key system intact.
5) Does the Schlage A501-941 retainer fit a deadbolt?
No. The A501-941 is a commercial replacement part for Schlage A Series and H Series full size interchangeable core cylinders, not deadbolt hardware. For deadbolt cylinder work, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
6) I need a replacement key-in-knob cylinder, not a retainer. What are my options?
The A501-941 is only the retainer that secures a core in a Schlage A or H Series lock, so it will not restore a lock with a bad cylinder. For a complete key-in-knob or key-in-lever cylinder, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1599 Series is a key-in-knob replacement cylinder, and the 1579 Series is a knob and lever cylinder made for Sargent locks. Falcon offers the A23161-05 G key-in-lever cylinder for RU and T Series locks with a 6-pin G keyway, keyed different with two cut keys.
7) What should I use on an aluminum storefront door instead of the Schlage A501-941?
The A501-941 serves Schlage A and H Series cylindrical locks and has no application in a narrow stile aluminum door. For storefront work, Adams Rite builds to that opening: the 4036 mortise cylinder is a Grade 1 five-pin cylinder with a 1/2 inch minimum door thickness, the 4024 cylinder pull with trim plate mounting and the 4025 five-pin cylinder pull with through-screws both suit the MS1847 deadlock/deadlatch, and the 4026 five-pin cylinder pull is made for the 5017 wood door deadlock/deadlatch.
8) Is a rim cylinder an alternative to the Schlage A501-941?
No - a rim cylinder mounts through the door and drives an exit device or surface deadbolt with a tailpiece, while the A501-941 is a retainer inside a Schlage A or H Series lock body. If a rim cylinder is what the opening needs, the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter for openings that need the look without a keyed function.
9) I want to keep the Schlage C keyway across my building. Is the A501-941 keyed?
The A501-941 is an unkeyed mechanical retainer - it holds the core in place and takes no part in keying, so it works with whatever keyway your A or H Series cores already use. If you need a keyed cylinder in the Schlage C keyway for other openings, the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder supplied in Schlage C keyway.
10) Is the A501-941 a commercial part or a residential one?
Commercial. Schlage classifies the A501-941 as commercial door hardware, and the typical uses are offices, schools, healthcare, government buildings, hospitality and multi-family properties running Schlage A or H Series locksets on interchangeable core master key systems.
11) Do I have to order anything else with the retainer to finish the repair?
Nothing is bundled with it. The A501-941 is a single service piece that drops into an existing A or H Series FSIC lock, so you need the lock body and the interchangeable core already on hand. If the core itself is damaged or you are rekeying, order the core separately.
12) For Emtek hardware, is the Schlage A501-941 the right service part?
It is not - the A501-941 is a genuine Schlage part matched to Schlage A and H Series interchangeable core cylinders. Emtek openings are served by the Emtek CY4 cylinder, sold each, or by the Medeco 1065244, a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
