Medeco 2000400T-26-DLT SC – Frequently Asked Questions

1) Will the Medeco 20200SC cylinder fit my Schlage lever locks?
The 20200SC is the Medeco M3 key-in-knob/lever cylinder cut with the DL keyway, which is the Schlage configuration. It is ordered by the specific Schlage lockset family it goes into, and the choices cover "ND" and "AL" Series, "A", "AL" and "D" Series, "A" Series (except Ply, Ply only, or Orbit only), "C" and "D" Series heavy duty knobs, "C, D" Series (Ply only), "S" Series, 5-pin "F" Series, 5-pin "F" Series lever made prior to 2004, 5-pin "F" Series lever made 2004 to 2007, and 6-pin "F" Series Orbit design. Pull the existing lockset and identify the series before you order, because the tailpiece differs between them.
2) Can I upgrade to Medeco high security without replacing my Schlage locksets?
That is exactly what this cylinder is for. The 20200SC drops into knob-type and lever-type cylindrical locksets, padlocks, and bored-type auxiliary deadlatches and deadlocks, so the existing hardware, prep and trim stay in the door and only the cylinder changes. Medeco builds over 100 cylinder designs and tailpiece configurations for that reason. For a property manager with a building full of Schlage cylindrical locks, this is a cylinder-only retrofit rather than a door hardware replacement.
3) Does the Medeco 20200SC stop unauthorized key copies at the hardware store?
Key control here is the point of the cylinder. The M3 key uses a utility patent, so blanks are restricted and a hardware store or kiosk cannot legally cut a duplicate. The Shuttle Pin movable element in the key also blocks 3D-printed copies. For a school, clinic or multi-tenant building where keys walk off with staff and tenants, that is the difference between rekeying a wing and not caring that a key went missing.
4) Is the Medeco 20200SC key-in-knob cylinder rated for drill and pick attack?
UL 437 Listed for both drill and pick resistance. The body is solid brass with hardened-steel inserts set in the areas a drill attack targets. Pick resistance comes from the M3 side pin system: 4 side pins, 3 finger pins plus 1 lift pin, that only align when the movable element in the key contacts them, and the key cuts are angled with fore and aft positioning rather than straight up and down.
5) I have older Schlage F Series levers, which Medeco cylinder do I need?
The "F" Series splits three ways on the 20200SC, and picking wrong gets you a cylinder that will not drive the latch. There is a 5-pin "F" Series option, a 5-pin "F" Series lever for units made prior to 2004, a separate 5-pin "F" Series lever for units made 2004 to 2007, and a 6-pin "F" Series for the Orbit design only. Check the manufacture date and the knob or lever style on the lock before ordering.
6) What do I have to specify when ordering a Medeco 20200SC cylinder?
Two things decide the part number. First, the Schlage lockset family it is going into, since that sets the tailpiece: options run from "A" Series and "A", "AL", "D" Series through "C" and "D" Series heavy duty knobs, "ND" and "AL" Series, "S" Series, and the 5-pin and 6-pin "F" Series variations including the two date-split 5-pin lever versions. Second, finish, in 13 choices. The keyway is fixed at DL and the cylinder is 6-pin.
7) What finishes does the Medeco 20200SC come in to match my existing Schlage trim?
Thirteen finishes, given in standard BHMA numbers so they line up with the trim already on your doors: 605 bright brass, 606 satin brass, 609 antique brass, 611 bright bronze, 612 satin bronze, 613 dark bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 20 antique nickel, 622 flat black, 624 dark bronze, 625 bright chrome, and 626 satin chrome. Most commercial openings are running 626 satin chrome or 613 oil-rubbed bronze.
8) Can my locksmith rekey a Medeco 20200SC without pulling it apart?
Yes. Set screw pin chamber caps let a locksmith pin and rekey the cylinder without disassembling it, which cuts the bench time on a tenant turnover or a lost-key call. The cylinder is 6-pin on the DL keyway, and the angled cuts plus fore and aft key positioning give enough combinations to run very large master key systems, so it will sit inside an existing Medeco M3 masterkeyed system.
9) Is the Medeco 20200SC a residential or commercial grade cylinder?
Commercial. The 20200SC is machined solid brass with hardened-steel inserts and is specified for office buildings, schools, healthcare, government and municipal facilities, retail, industrial and warehouse space, and multi-tenant residential. It is a security upgrade to existing Schlage cylindrical hardware rather than a house-grade replacement cylinder.
