Medeco 100403 6-Pin Rim Cylinder with Sargent Mounting Style and Horizontal/Vertical Tailpiece

The Medeco 100403 is a high-security 6-pin rim cylinder engineered for Sargent mounting style applications, featuring a horizontal/vertical tailpiece for compatibility with a wide range of auxiliary rim locks including surface-mounted deadbolts, night latches, panic devices, and jimmyproof locks. Constructed from brass and rated Grade 1 Heavy Duty for commercial use, this cylinder incorporates Medeco's advanced M4 design with UL 437 listing for drill and pick resistance. The M4 platform delivers utility-patented key control, protecting against unauthorized key duplication while supporting masterkeying into systems containing M4 BiLevel cylinders.

Key Features

  • 6-Pin Configuration: Features a 6-pin tumbler design for enhanced security depth and key combination complexity in commercial applications.
  • Horizontal/Vertical Tailpiece: Dual-orientation tailpiece provides flexible compatibility with surface-mounted deadbolts, night latches, panic devices, and jimmyproof (interlocking deadbolt) locks.
  • Patented Key Control (M4): Utility-patented key control protects against unauthorized duplication, requiring a special key cutting machine and access to Medeco-specific key blanks.
  • UL 437 Listed: Certified for drill and pick resistance, providing verified protection against physical attack methods including bumping and picking.
  • Sidebar Security Mechanism: M4 cylinders use a sidebar that prevents key rotation until the key is elevated, rotated, and aligned in the correct position, offering superior bump and pick resistance.
  • Masterkey Compatible: Can be masterkeyed into a system containing M4 BiLevel cylinders for flexible access control hierarchy in commercial facilities.
  • Broad Hardware Compatibility: Available in a wide variety of formats, retrofitting most hardware on the market today, including other manufacturers' mortise lock cases and rim lock applications.

Medeco MED-100403H-26-00P-Y02 – Frequently Asked Questions

1) Will a Medeco 100403 rim cylinder fit a Sargent rim exit device?
The 100403 is built to the Sargent mounting style, so it drops into rim hardware that takes a Sargent-mount cylinder. The tailpiece is the other half of the decision: it ships horizontal or vertical, and you pick CT-Y02 or CT-Y32 as the rim tailpiece on the order. Match the tailpiece orientation to the way your device's actuator sits, and the cylinder does the rest.
2) What kind of locks can a Medeco 6-pin rim cylinder with horizontal/vertical tailpiece operate?
Surface-mounted deadbolts, night latches, panic devices, and jimmyproof (interlocking deadbolt) locks. The dual-orientation tailpiece is what makes that range work: horizontal drives one style of auxiliary rim lock, vertical the other, so the same 100403 covers both the storefront night latch and the jimmyproof on an apartment door.
3) Which Medeco keyway do I order to match the cylinders already in my building?
Key technology is a choice on the 100403, and it covers Original, Biaxial, M3, BiLevel, and KeyMark. Order the one that matches the system you already run, because these are not interchangeable, a Biaxial key will not operate an M3 cylinder. If you are extending an existing Medeco masterkey system, the platform your current cylinders use is the answer, and your Medeco dealer holds the key records for it.
4) Is the Medeco 100403 rim cylinder UL 437 listed and what grade is it?
UL 437 listed for drill and pick resistance, and BHMA Grade 1 heavy duty. That combination is what a spec on a government, healthcare, or school project usually calls for when it asks for a high-security cylinder. The body is brass, rated for commercial duty rather than residential.
5) Can tenants copy a Medeco M4 key at a hardware store?
No. The M4 platform carries utility-patented key control, so duplication takes a special key cutting machine and access to Medeco-specific key blanks. For multi-tenant and mixed-use property, that is the practical difference from a standard rim cylinder: keys do not walk, and you are not rekeying a building because someone made copies at the corner store. The sidebar mechanism also means the key has to be elevated and rotated into position before the plug will turn, which is where the bump and pick resistance comes from.
6) Can a Kaba Ilco 7010 dummy rim cylinder replace a keyed rim cylinder?
No. The Kaba Ilco 7010 is a dummy rim cylinder in a 1 1/8 inch body, so it fills the cylinder hole and matches the trim without operating anything. If the leaf needs to actually retract or throw the rim lock by key, the keyed 6-pin Medeco 100403 with its horizontal/vertical tailpiece is the part that does that work. Dummy cylinders are for inactive leaves and blank-off applications only.
7) What is a simpler replacement rim cylinder than a Medeco 100403 when patented key control is not required?
The Kaba Ilco 605 Series replacement rim cylinder is a 5-pin cylinder in a satin brass finish, sold by 10s. It is a straightforward replacement for a standard rim lock where the opening does not need restricted keys. The Medeco 100403 is a 6-pin cylinder built on the M4 platform with utility-patented key control and UL 437 listing for drill and pick resistance, which is what you specify when duplication has to be controlled and the cylinder has to resist attack.
8) Should I order the rim cylinder pinned or sub-assembled?
Pinned means it comes keyed and ready to install. Sub-assembled ships without the final pinning so a locksmith can key it into an existing Medeco system on the bench. If you are a property manager replacing one cylinder and want it working out of the box, take pinned. If you are a locksmith building or extending a masterkey system, sub-assembled is the one you want.
9) Can a Medeco 100403 be masterkeyed into an existing system?
Yes. The 6-pin 100403 can be masterkeyed into a system containing M4 BiLevel cylinders, which is how facilities run a building master over individual tenant keys. BiLevel is also one of the key technology options you can order it in, so you can spec the cylinder on the same platform your existing masterkey system runs.
10) What is the difference between a Medeco high-security rim cylinder and a Kaba Ilco replacement rim cylinder?
Different jobs. The Medeco 100403 is a 6-pin, UL 437 listed, Grade 1 brass cylinder with patented key control, which is what you buy when you need keys that cannot be duplicated. The Kaba Ilco 605 Series replacement rim cylinder is a 5-pin standard cylinder sold by the 10, which is what you buy when you are swapping out worn cylinders across a lot of doors and key control is not the issue. If your problem is unauthorized copies, the Ilco does not solve it.
11) I need a thumbturn on the inside of a rim night latch, not a key cylinder. Is this the right part?
No. The 100403 is a keyed rim cylinder. For the inside of a rim device where you want turn operation instead of a key, use a turnknob rim cylinder such as the Kaba Ilco 7011 in the 1-1/8 inch rim size, or the ADA 7011 version with the larger turn piece where accessible operation is required. If the inside just needs to fill the hole with no operation at all, the Ilco 7010 dummy rim cylinder is the part.
12) Will a Medeco rim cylinder retrofit hardware from other manufacturers?
Medeco cylinders are made in a wide range of formats and retrofit most hardware on the market, including other manufacturers' mortise lock cases and rim lock applications. The 100403 specifically is the Sargent mounting style rim version, so it is the right one where the device takes a Sargent-mount rim cylinder. For a different mounting style, you want the matching format from the same family rather than this one.
13) Which rim cylinder should be used on an ADA opening with a thumbturn instead of a key?
The Kaba Ilco ADA 7011 is a 1 1/8 inch turnturn rim cylinder built for that application, giving a thumbturn operation rather than a keyed one. The Medeco 100403 is the keyed side of the same opening: a 6-pin rim cylinder in Sargent mounting style, Grade 1 heavy duty brass, for the secure exterior face. Many openings use both, a keyed cylinder outside and a turn inside.
14) Is a 5-pin rim cylinder interchangeable with a 6-pin Medeco rim cylinder in a masterkey system?
They are not interchangeable within one key system. The Medeco 100403 is a 6-pin cylinder that masterkeys into a system containing M4 BiLevel cylinders and uses Medeco-specific key blanks cut on a special machine. The Kaba Ilco 605 Series is a 5-pin replacement cylinder on its own keying. If a facility is standardizing a masterkey hierarchy on the M4 platform, every rim opening in that system needs to stay on the 6-pin Medeco cylinder rather than mixing in a 5-pin body.
15) What finishes does the Medeco 100403 rim cylinder come in to match my existing door hardware?
Thirteen finishes, covering the standard BHMA numbers you would be matching on a commercial opening: 605 bright brass, 606 satin brass, 609 antique brass, 611 bright bronze, 612 satin bronze, 613 dark bronze oil-rubbed, 624 dark bronze, 618 bright nickel, 619 satin nickel, 20 antique nickel, 622 flat black, 625 bright chrome, and 626 satin chrome. On most commercial jobs the ring will be 626 or 613, so match the number on the trim rather than the description.
16) Do the Medeco 100403 and the Kaba Ilco rim cylinders use the same finishes?
They are specified differently. The Kaba Ilco 605 Series replacement rim cylinder is supplied in satin brass. The Medeco 100403 is ordered in a finish of your choice across a range that includes 605 bright brass, 606 satin brass, 613 dark bronze oil-rubbed, 619 satin nickel, 622 flat black and 626 satin chrome, so it can be matched to existing trim on a fleet of doors rather than to a single stock finish.
