Medeco 20009S4T-26-DLT – Frequently Asked Questions

1) Will the Medeco 20009S4 cylinder fit an Olympus 700LCM cabinet lock?
Yes. The 20009S4 is a 6-pin key-in-knob/lever retrofit cylinder built to drop into Olympus 700LCM and 800LCM, Cal-Royal T-300 Series, and Schlage Lazy Motion knob locksets. You keep the existing lockset and swap only the cylinder, so there is no door prep and no new hardware to mount.
2) Is this Medeco retrofit cylinder UL437 listed for drill and pick resistance?
Yes, the 20009S4 carries a UL437 listing for drill and pick resistance. It also meets ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength, and ANSI/BHMA A156.5 Grade 1 for heavy-use commercial service. If your facility spec calls for a UL437 cylinder on existing cylindrical locks, this is the retrofit route.
3) What do I have to specify when ordering a Medeco 20009S4 cylinder?
Three things. Keyway technology, either Biaxial or M3. Pinning, either Pinned, Sub-Assembled, or Sub-Assembled No Slider. And finish, from 13 options including 605 bright brass, 606 satin brass, 613 dark bronze oil-rubbed, 619 satin nickel, 622 flat black, 626 satin chrome and others. Sub-assembled is what you order if your locksmith is pinning to an existing master key system in house.
4) Can I add these cylinders to an existing Medeco Biaxial master key system?
Yes, if you order the Biaxial keyway option rather than M3. Both technologies are offered on the 20009S4, and you should match whatever your building's existing Medeco system runs on. Order the Sub-Assembled version if your locksmith will pin them to your system's bitting, or Pinned if you want them keyed by the factory.
5) Do I need to replace the whole knob lockset to upgrade to Medeco high security?
No. The 20009S4 replaces just the cylinder inside knob-type and lever-type cylindrical locksets, padlocks, and bored auxiliary deadlatches and deadlocks. That gets you UL437 drill and pick resistance and restricted key control while the existing lockset, door prep, and strike stay as they are. Medeco builds over 100 cylinder and tailpiece configurations, so other hardware brands on your other doors likely have a matching retrofit too.
6) What is the difference between the Pinned and Sub-Assembled options on a Medeco cylinder?
Pinned means the cylinder ships keyed and ready to install. Sub-Assembled ships without final pinning so a locksmith can key it into an existing system, and Sub-Assembled No Slider leaves the slider out as well for shops doing their own full build. If you are a property manager without a locksmith on staff, order Pinned.
7) Is the Medeco 20009S4 rated for heavy traffic commercial doors?
It is. The cylinder holds ANSI/BHMA A156.5 Grade 1 certification, the heavy-use commercial level, and the components are machined brass. It is catalogued as a commercial-duty part, and typical placements are offices, schools, healthcare, government buildings, retail, and multi-tenant residential where key control is the driver.
8) Does a 6-pin Medeco cylinder give better key control than a standard 5-pin?
The 20009S4 uses a 6-pin tumbler configuration, which expands the number of usable key changes and matters when you are building a master key system across a facility. Beyond pin count, the M4 and M3 key control technology is utility patent-pending, so keys cannot be legally duplicated off the street. That combination is what earns the A156.30 Level A rating.
9) Will a Medeco 20009S4 match the finish on the rest of my building's door hardware?
Most likely. 13 BHMA finishes are offered: 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. 626 satin chrome and 613 are the two you will most often be matching on commercial openings.
