Schlage D500-000 – Frequently Asked Questions

1) What does the Schlage D500-000 core spacer actually do in an AL or ND lockset?
The D500-000 is a spacer that sits behind a small format interchangeable core in Schlage AL Series and ND Series cylinder applications, holding the core at the correct depth and alignment inside the lock. Without it, an SFIC can sit too deep or shift, and the control key and throw member will not engage properly. It is a genuine Schlage part, not a housing or a core, so it does not key anything on its own.
2) Is the Schlage D500-000 a replacement core, or do I still need to order a keyed SFIC core separately?
The D500-000 is a core spacer, not a keyed cylinder core. It is a replacement part that positions and aligns a small format interchangeable core in Schlage AL Series and ND Series SFIC applications, so the keyed core itself is a separate order. For the core, the BEST 1C Series is a standard 5-pin cylinder core, and the BEST 1CB is a Peaks 150 Series interchangeable core cylinder. Order the spacer and the core together if the opening needs both.
3) My Schlage mortise lock needs an interchangeable core cylinder. Will the D500-000 work there?
No. The D500-000 is built for Schlage AL Series and ND Series cylindrical SFIC configurations, not for mortise bodies. For a mortise opening the part you want is a mortise cylinder housing, such as the Corbin Russwin 1080 Grade 1 Series 1-1/2 inch LFIC mortise cylinder, 6-pin, listed for Schlage L9000 mortise locks with an A01 Schlage L cam. Note that is a large format interchangeable core housing, so the keying system differs from small format.
4) What do I order instead of the D500-000 if the lock is a key-in-lever rather than an SFIC prep?
The D500-000 only has a job when the AL or ND lockset is configured for a small format interchangeable core. If the lever is a conventional key-in-lever prep, you want a key-in-lever cylinder instead: the Falcon A23161-05 G is a key-in-lever cylinder for RU/T Series with a 6-pin G keyway, keyed different with two cut keys, and the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder. Those replace the cylinder outright, where the D500-000 is only a fitment component.
5) Is the D500-000 a commercial part or is it for residential Schlage locks?
Commercial. Schlage AL and ND Series are commercial lever lines, and the D500-000 is catalogued as a commercial replacement part for those. Residential Schlage knob and deadbolt lines do not use small format interchangeable cores, so this spacer has no application there.
6) We are standardizing our campus on SFIC master keying with Schlage ND levers, what do we order alongside the cores?
For an SFIC conversion on ND or AL Series hardware you need the interchangeable core itself plus the D500-000 core spacer to seat it correctly in the lock. The spacer is the piece most often lost during a rekey or a lock teardown, and it is worth carrying spares in the shop if you run SFIC across a facility. Cores are keyed and controlled separately, so the spacer is the same regardless of keyway or master key level.
7) I need a drill resistant core behind the D500-000 spacer for a high security opening. What core should I be looking at?
The D500-000 spacer itself is a commercial fitment part and carries no security rating. For a higher security small format core, the BEST 1CDF is a drill resistant patented interchangeable core, 7-pin, brass, in the 150 Series. That is a core choice rather than a spacer choice, so the spacer decision does not change when you step up the core.
8) We are standardizing on interchangeable cores across a campus. Does the D500-000 spacer limit which other openings we can bring onto the same system?
The D500-000 addresses one hardware family: Schlage AL Series and ND Series SFIC locksets. Other opening types need their own core-accepting hardware. Rim exit devices take a rim cylinder such as the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, and mortise locks take a mortise housing such as the Corbin Russwin 1070 Grade 1 Series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Matching keyway and core format across those housings is what keeps the system unified, not the spacer.
9) Will the D500-000 help me put a keyed cylinder into an aluminum storefront door?
No, the D500-000 is matched to Schlage AL and ND Series cylindrical locksets, not to narrow stile storefront hardware. For an aluminum storefront deadlock you would look at Adams Rite hardware instead, such as the 4036 mortise cylinder with five-pin security, Grade 1, with a 1/2 inch minimum door thickness, or the 4025 five pin tumbler cylinder pull with through-screws for the MS1847 deadlock.
10) The Detex MC65 lists a Schlage C keyway. Can I use it in place of the D500-000?
Not as a substitute. The Detex MC65 is a mortise cylinder with a Schlage C keyway, 1-1/8 inch, 6-pin, commercial grade. It shares a keyway with many Schlage systems, but it is a conventional mortise cylinder, while the D500-000 is a spacer component for small format interchangeable core setups in AL and ND Series cylindrical locks. Different hardware prep, different function.
11) Is the D500-000 a genuine Schlage part or an aftermarket copy?
Genuine Schlage. It is made to Schlage tolerances as a drop-in component for AL and ND Series SFIC applications, which matters here because the spacer sets core depth, and a part that is slightly off will bind the core or prevent the control key from pulling it.
12) Does the D500-000 come in different sizes or finishes?
No options to pick. The core spacer is sold as a single part under model number D500-000, with no finish or size choices, so there is nothing to specify beyond the quantity you need.
13) Is a dummy core the same thing as the D500-000 spacer for filling an unused core hole?
They are different parts. The D500-000 is a spacer that aligns a working small format core in a Schlage AL or ND Series lockset. A dummy cylinder such as the BEST 12E Series dummy rim cylinder, 1-5/32 inch diameter, is a non-functioning cylinder used where no keyed operation is wanted. Choose by whether the opening is meant to key or not.
