Medeco 100200 Original Standard 6-Pin Mortise Cylinder — 1-1/8" to 1-3/4", Straight Cam, 00 Keyway, UL 437 High Security

The Medeco 100200 Original Standard 6-Pin Mortise Cylinder delivers unmatched high-security protection for commercial and institutional applications, engineered to thread directly into standard mortise lock cases with a rear-mounted straight cam and set screw retention. Sized from 1-1/8" to 1-3/4" and configured with the 00 Keyway and a 6-pin tumbler system, this cylinder is UL 437 listed for resistance against drilling, picking, and bumping. Built from brass and powered by Medeco's patented M4 technology, it provides superior key control and seamless integration with most commercial mortise hardware platforms.

Key Features

  • Precise Length Range: Accommodates door and lock applications requiring cylinder lengths from 1-1/8" to 1-3/4", providing versatile fit across a wide range of mortise lock cases.
  • 6-Pin Tumbler Configuration: The 00 Keyway, 6-pin design delivers an expanded key combination matrix for enhanced key control and master keying flexibility.
  • Straight Cam Operation: Rear-mounted straight cam operates the internal locking mechanism of standard mortise lock cases; set screw secures the cylinder firmly in place.
  • UL 437 Certified Drill Resistance: Fortified with hardened steel inserts and rotating anti-drill pins, providing certified resistance against drilling, picking, and bumping attacks.
  • Patented M4 Key Control: Keys can only be duplicated by authorized Medeco dealers with proof of authorization, using proprietary special angle-cut key blanks and cutting equipment to prevent unauthorized duplication.
  • Sidebar Locking Mechanism: Requires precise alignment of multiple key elements before rotation, protecting against picking and bumping beyond standard pin tumbler security.
  • Master Keying Capable: Integrates into M4, M4 BiLevel, and M4 CLIQ systems for complex, multi-level access management in large facilities.
  • Brass Construction: Heavy-duty brass substrate ensures long-term durability and corrosion resistance in demanding commercial environments.
  • Retrofit-Ready Design: Ideal for retrofits with existing mortise hardware; compatible with most commercial hardware platforms and available with a wide range of cam styles to fit most manufacturers' locks.

Medeco 100200-26-00P – Frequently Asked Questions

1) Will the Medeco 100200 mortise cylinder fit my existing mortise lock case?
The 100200 threads into standard mortise lock cases and is held by the lock case set screw, with a rear-mounted cam driving the lock. It comes in six lengths, 1-1/8, 1-1/4, 1-3/8, 1-1/2, 1-5/8 and 1-3/4 inches, so measure the cylinder you are pulling out from the face of the ring to the back of the housing and match that. Cylinder length has to suit the lock case and the door thickness together, so on a thicker door with a deep escutcheon you move up a length rather than shimming a short one.
2) Is the Medeco 100200 a high security cylinder, and what does UL 437 actually mean on it?
UL 437 listed, which is the physical attack standard for cylinders: it covers drilling, picking and forced entry. The 100200 backs that with hardened steel inserts and rotating anti-drill pins, and a sidebar that requires several key elements to align before the plug will turn, which is what defeats picking and bumping. It also carries ANSI/BHMA Grade 1 and a heavy duty rating, so it belongs on commercial openings, not light residential duty.
3) Can tenants get Medeco 100200 keys copied at a hardware store?
No, and that is the point of the cylinder. The 100200 runs Medeco's patented M4 system on angle-cut key blanks that require proprietary cutting equipment, and blanks are only issued to authorized Medeco dealers against proof of authorization. For a property manager or facility with turnover, that means keys leave the building but copies do not appear on their own.
4) What do I have to specify when ordering the Medeco 100200 besides length and finish?
Three things beyond length and finish. Keying is required: keyed different, keyed alike, or key code if you are matching an existing system by bitting. Pinning is either factory pinned or sub-assembled, sub-assembled being the option a locksmith takes when pinning the cylinder into their own keying system in-house. Cam type is optional and defaults to the straight cam, so specify a cam only if the lock case needs a different one.
5) Can the Medeco 100200 be master keyed into an existing building master key system?
Yes, if that system is Medeco M4. The 100200 is a 6-pin cylinder on the 00 keyway and integrates into M4, M4 BiLevel and M4 CLIQ systems, so it can be added as a change key, master or grand master level within an existing M4 hierarchy. Order it key code or sub-assembled so it can be cut or pinned to the system's bitting. It will not master into a different manufacturer's system or a different Medeco keyway.
6) Should I use a mortise cylinder or a rim cylinder for my door?
It depends entirely on the lock, not the door. A mortise cylinder like the 100200 threads into the lock case body and turns a cam at the rear, which is what a mortise lockset or a mortise-prepped exit device trim takes. A rim cylinder mounts through the door with a tailpiece and screws from the inside, and it is what a rim exit device or a surface-mounted night latch takes. They are not interchangeable, so look at what is on the door now: threaded body with a set screw in the lock case edge means mortise.
7) What is the difference between Medeco Original and the other Medeco cylinder lines?
The 100200 is Medeco's Original technology platform, running the M4 keyway family with the angled-cut key and sidebar. That is the identifier a distributor needs when matching a reorder: model 100200, Original technology, 6-pin, 00 keyway. Ordering a different Medeco technology line will not key to an existing Original system even at the same length and cam.
8) I need several Medeco cylinders keyed alike across one building. How do I order that?
Select keyed alike on the 100200 and all cylinders in that order group are cut to the same key. If you are adding to doors already running Medeco Original 00 keyway cylinders, order key code instead and supply the existing bitting so the new cylinders operate the keys already in circulation. Different lengths and different cams can all be keyed alike together, since keying is independent of the body length and cam selection.
9) Will the Medeco 100200 match the finish on the rest of my door hardware?
Thirteen finishes are offered on the 100200, so a match is usually available: 20 antique nickel, 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, 622 flat black, 624 dark bronze, 625 bright chrome and 626 satin chrome. Most commercial buildings are running 626 satin chrome or 613, so match the BHMA number on your existing trim rather than the finish name.
10) Is the Medeco 100200 cylinder durable enough for an exterior or high-traffic commercial door?
Brass body, Grade 1, heavy duty rated and built for commercial use, so it holds up on entry doors that see constant cycling. Brass also resists corrosion, which matters on an exterior opening. Pair it with a weather-appropriate finish such as 613 dark bronze oil-rubbed or 626 satin chrome for exterior trim.
