Schlage L583-490 – Frequently Asked Questions

1) Does buying the L583-490 get me a cylinder too, or do I need to order that separately?
The retainer only. The L583-490 is a replacement part, so if the cylinder itself is worn, keyed wrong, or damaged, you order that as a separate line. For an L Series mortise lock the matching cylinder side is the large-format interchangeable core style, for example the Corbin Russwin 1080 1-1/2 inch 6-pin LFIC mortise cylinder with the A01 Schlage L cam, which is built for Schlage L9000 mortise locks.
2) Does the Schlage L583-490 replace the mortise cylinder itself, or just hold it in place?
The L583-490 is a cylinder retainer - a replacement part that holds and aligns the cylinder inside a Schlage L Series mortise lock body manufactured after January 1998. It is not a keyed cylinder. If the cylinder itself is worn, damaged, or being rekeyed, you need an actual mortise cylinder such as the Corbin Russwin 1000 Grade 1 series mortise cylinder in 1-1/2 inch length with an A02 straight cam, or the Detex MC65 mortise cylinder with Schlage C keyway, 1-1/8 inch, 6-pin. Order the retainer when the retaining hardware is the failed part and the cylinder is still good.
3) I want to convert Schlage L Series mortise locks to interchangeable core keying - is the L583-490 what I need?
No. The L583-490 is a retainer that secures a conventional cylinder in a Schlage L Series mortise body. To move an L Series opening to an interchangeable core system, look at the Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, which is built for Schlage L9000 mortise locks and uses an A01 Schlage L cam. If you are standardizing a facility on BEST small format cores, the BEST 1CB 150 series interchangeable core cylinder and the BEST 1CDF drill resistant patented 7-pin brass 150 series core are the housings and cores in that program.
4) What should I order instead of the L583-490 if the door is an aluminum storefront rather than a mortise lock opening?
The L583-490 is a commercial replacement part specific to Schlage L Series mortise lock cylinders, so it has no role in a narrow stile storefront. For those openings, Adams Rite offers the 4036 mortise cylinder, a Grade 1 part with five-pin security and a 1/2 inch minimum door thickness, plus cylinder pulls such as the 4024 with trim plate mounting and the 4025 five pin tumbler version with through-screws, both intended for the Adams Rite MS1847 deadlock or deadlatch. For a wood door deadlock, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock or deadlatch.
5) Is this a genuine Schlage part or an aftermarket copy?
It is a genuine Schlage component, model L583-490, built as the factory replacement for the original retainer in the L Series cylinder assembly.
6) Can I standardize on this part across a building full of Schlage L Series locks?
Yes, if the locks are the post-January 1998 L Series cylinders. The retainer is a single part number, L583-490, with no finish, handing, or size options to sort out, so one line item covers every matching opening in the facility.
7) My Schlage L Series mortise lock predates 1998 - can I still use the L583-490 retainer?
The L583-490 is engineered for Schlage L Series mortise lock cylinders manufactured after January 1998, so it should not be assumed to fit earlier bodies. If the older lock is at end of life, a full cylinder replacement sized to the prep is the cleaner path: the Corbin Russwin 1070 Grade 1 series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam and the Corbin Russwin 1000 series 1-1/2 inch mortise cylinder with an A02 straight cam cover the two common mortise lengths, with cam style chosen to match the lock body.
8) The lock on my door is a lever with a key in the lever, not a mortise - what replaces the cylinder there?
The L583-490 retainer applies to Schlage L Series mortise lock cylinders and will not serve a key-in-lever or key-in-knob lock. For those, Kaba Ilco makes the 1539 series key-in-knob and lever universal cylinder, the 1599 key-in-knob replacement cylinder, and the 1579 knob and lever cylinder for Sargent. On Falcon RU/T series levers, the A23161-05 G is a 6-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys.
9) Is a rim cylinder an acceptable substitute for the part the L583-490 retains?
No - rim cylinders mount through the door face and drive a tailpiece, while the L583-490 retains a threaded mortise cylinder inside a Schlage L Series lock body. Rim options in the same catalog serve different hardware: the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, the Medeco 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065244 5-pin lazy motion rim type cylinder with an Emtek tailpiece, and the Medeco 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Match the cylinder type to the lock body rather than to the keyway alone.
10) Is the L583-490 suitable for high-traffic commercial doors, or is it a residential part?
Commercial. The retainer is part of Schlage's L Series commercial mortise platform and is used in offices, schools, healthcare, government buildings, multi-tenant residential, retail and hospitality, and industrial facilities.
11) Can I use a dummy cylinder or a bare core in place of the L583-490?
They solve different problems. The L583-490 is the retaining part that keeps a working cylinder seated in a Schlage L Series mortise lock. A BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills an opening where no keyed function is wanted, and a BEST 1C series standard 5-pin cylinder core is the keyed core that drops into a compatible interchangeable core housing rather than into an L Series mortise body. Choose the retainer only when the existing cylinder is sound and the retention hardware is what failed.
12) Is the L583-490 appropriate for residential handlesets and deadbolts?
The L583-490 is designated a commercial part built around Schlage L Series mortise lock hardware, so it has no application in a residential handleset or deadbolt. For that work, the Emtek CY4 cylinder is sold individually, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the Kaba Ilco 1549 series is a key-in-deadbolt cylinder.
