Medeco 2020052T-26-DLT – Frequently Asked Questions

1) Can I put a high security cylinder in my existing knob locks without replacing the whole lockset?
That is exactly what the Medeco 2020052 is for. It's a key-in-knob/lever cylinder that retrofits knob type cylindrical locksets, lever type cylindrical locksets, padlocks, and bored type auxiliary deadlatches and deadlocks. You keep the lock body, chassis, and trim already on the door and swap only the cylinder, so a building can be moved onto restricted keys without pulling hardware off every opening.
2) Is the Medeco 2020052 UL 437 listed for drill and pick resistance?
Medeco M4 key-in-knob cylinders are UL 437 listed for drill and pick resistance. The 2020052 also carries ANSI A156.30 Level A for patent-protected key control and physical strength, and ANSI A156.5 Grade 1 for heavy use. For an institutional spec that calls out a UL 437 listed high security cylinder, those three lines are what you cite.
3) What is the difference between the Biaxial and M3 versions of the Medeco 2020052?
Two keyway technologies are orderable on the 2020052: Biaxial and M3. The one you pick has to match the system the building is already keyed on, because a Biaxial key will not operate an M3 cylinder and the reverse is also true. If you're adding cylinders to an existing Medeco master key system, order the technology that system was built in. If you're starting fresh, M3 is the one carrying the ANSI A156.30 Level A and A156.5 Grade 1 certifications called out for this cylinder.
4) Do I order the Medeco 2020052 pinned or unpinned?
Three build states are offered: Pinned, Sub-Assembled, and Sub-Assembled No Slider. Pinned comes keyed and ready to install, which is what a property manager or facility buyer wants. Sub-Assembled ships without the pinning done, for a locksmith or dealer who is combinating it into an existing master key system on their own bench. Sub-Assembled No Slider leaves the slider out as well, for a shop building the cylinder up completely in house.
5) My locks aren't Schlage C or D Series. Is there another Medeco key-in-knob cylinder that fits?
Likely, yes. Medeco publishes over 100 cylinder designs and tailpiece configurations across the key-in-knob/lever line, which is what gives it the broadest retrofit range in the category. The 2020052 is the one cut for Schlage C and D Series heavy duty knobs and new standard padlocks. For a different lockset, identify the lock manufacturer and series first, then match the cylinder and tailpiece to that lock rather than adapting this one.
6) What finishes does the Medeco 2020052 come in to match my existing hardware?
Thirteen finishes are orderable on the 2020052: 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. Match the BHMA number on the knob you're retrofitting, since the cylinder face is the visible part once it's in.
7) Is the Medeco 2020052 cylinder good enough for a commercial building or is it a residential part?
Commercial. The 2020052 is machined brass, certified to ANSI A156.5 Grade 1 for heavy use applications, and Medeco classes it for commercial duty. Typical placements are office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government facilities, all of which run cycle counts a residential cylinder does not survive.
8) Will keys for the Medeco 2020052 stop tenants from getting copies cut at the hardware store?
The 2020052 uses Medeco's utility patent-pending key control, which restricts unauthorized duplication. That is the practical reason a property manager buys this cylinder over a standard one: blanks are controlled, so a departing tenant or contractor cannot walk into a big box store and copy the key. It controls the key, not the lock body, so you get that on the hardware already hanging on your doors.
9) Can I use one Medeco key system across both my door knobs and my padlocks?
Yes. The 2020052 fits Schlage C and D Series heavy duty knobs and new standard padlocks, so gates, storage cages and doors can run on the same 6-pin Medeco system with one key. Order the same technology, Biaxial or M3, across every cylinder in that system so all of them accept the key.
