Medeco 2020000T-26-DLT – Frequently Asked Questions

1) Can I put Medeco cylinders in my padlocks without replacing the padlocks themselves?
That is exactly what the 2020000 does. It is a retrofit cylinder for Abus 83KNK, American 3600/3700, and Master 29, 6600, and 6700 Pro Series padlock bodies, so a facility standardizing on Medeco key control can convert the padlocks it already owns instead of buying new locks. The cylinder itself is machined brass and carries UL 437 listing for drill and pick resistance.
2) What do I have to specify when ordering a Medeco 2020000 padlock cylinder?
Three choices. Keyway technology is either Biaxial or M3. Pinning is Pinned, Sub-Assembled, or Sub-Assembled No Slider. Finish is one of 13: Antique Nickel (20), Bright Brass (605), Satin Brass (606), Antique Brass (609), Bright Bronze (611), Satin Bronze (612), Dark Bronze Oil-Rubbed (613), Bright Nickel (618), Satin Nickel (619), Flat Black (622), Dark Bronze (624), Bright Chrome (625), and Satin Chrome (626).
3) Does the Medeco 2020000 cylinder stop unauthorized key copying?
Key control is the main reason to buy it. The 2020000 uses Medeco's patent-protected M4 key control technology to restrict unauthorized duplication, and it is certified to ANSI A156.30 Level A for patent-protected key control and physical strength. For a school or hospital where gate and cage padlock keys tend to wander, that is what keeps the key ring closed.
4) Will a Medeco 2020000 padlock cylinder work in a door lock or an exit device?
No. The 2020000 is built to the key-in-knob/lever cylinder format for the Abus, American, and Master padlock bodies it lists, not for mortise or rim prep. For a rim device you want a rim cylinder such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam; for a mortise lock, a mortise cylinder like the Corbin Russwin 1000 Series 1-1/2 inch with an A02 straight cam.
5) What is the difference between the Medeco 2020000 padlock retrofit cylinder and a Corbin Russwin 1070 mortise housing?
They go into different kinds of hardware. The Medeco 2020000 is a 6-pin retrofit cylinder made to drop into Abus 83KNK, American 3600/3700, and Master 29, 6600, and 6700 Pro Series padlocks. The Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, which threads into the cylinder pocket of a mortise lock body. If the opening is a padlock shackle, the 2020000 is the part; if it is a mortise lockcase, the CR1070-114-A01 is the one that fits.
6) I need a Medeco-style key control upgrade on an exit device rim cylinder, not a padlock. What takes the place of the 2020000?
The 2020000 is built for padlock bodies, so a rim application needs a rim cylinder instead. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Which of the two you order depends on the tailpiece orientation the device chassis expects. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece if the device needs a longer reach.
7) If I want an interchangeable core system instead of a fixed retrofit cylinder like the Medeco 2020000, what should I look at?
The 2020000 is a pinned or sub-assembled fixed cylinder in Biaxial or M3 technology, so rekeying means pinning the cylinder. For a system where a control key pulls the core, the BEST 1CB is a 150 Series interchangeable core cylinder, and the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass, also 150 Series. On the Schlage side, the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those change cores in seconds; the 2020000 stays with the padlock body it retrofits.
8) Does the Medeco 2020000 work in an aluminum storefront deadlock the way an Adams Rite cylinder does?
No. The 2020000 is a padlock retrofit cylinder for Abus 83KNK, American 3600/3700, and Master 29, 6600, and 6700 Pro Series bodies. Narrow stile storefront work uses different parts: the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security and a 1/2 inch minimum door thickness, and the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock. For a wood door version of that pull, the 4026 is made for the Adams Rite 5017 wood door deadlock/deadlatch.
9) I have a Schlage C keyway facility. Can I keep the 2020000 on the same key as my other cylinders?
Not on a C keyway. The Medeco 2020000 comes in Biaxial and M3 technology, which are patent-protected keyways with restricted duplication, so it keys to a Medeco system rather than to conventional keyways. Cylinders like the Detex MC65, a 1-1/8 inch 6-pin commercial mortise cylinder in Schlage C keyway, and the Schlage 20-057-C full size interchangeable core in C keyway, run on the C system. Facilities usually run the Medeco cylinders as their own restricted key group covering the padlocks.
10) Which cylinder should I order for a Schlage L9000 mortise lock instead of the Medeco 2020000?
The Corbin Russwin 1080 is the one built for that lock: a Grade 1 Series 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 cloverleaf cam. The Corbin Russwin 1000 is a Grade 1 mortise cylinder at 1-1/2 inch length with an A02 straight cam if the cam style called out is straight rather than cloverleaf. The Medeco 2020000 stays with the padlock platforms it is cut for.
11) What is the difference between the Pinned and Sub-Assembled options on a Medeco retrofit cylinder?
Pinned means the cylinder arrives keyed and ready to install. Sub-Assembled ships for a locksmith to pin to your own key system, and Sub-Assembled No Slider leaves the slider out as well, which is how a shop building Biaxial or M3 cylinders into an existing masterkey system usually wants them. If you are not pinning cylinders in-house, order Pinned.
12) Should I order the Biaxial or the M3 version of the Medeco 2020000?
Match whatever your existing Medeco system runs on. Biaxial and M3 are different keyway platforms, and keys are not interchangeable between them, so a facility already keyed in one has to stay in it for the padlocks to fall onto the same key. If you are starting fresh, the choice is set by which system your Medeco dealer maintains your key records under.
13) Is the Medeco 2020000 rated for heavy commercial use?
It is certified to ANSI/BHMA A156.5 Grade 1 for heavy-use applications and to ANSI A156.30 Level A, with UL 437 listing for drill and pick resistance. The catalog classes it as a commercial product, and the body components are machined brass.
14) What is a cheaper replacement cylinder if I do not need Medeco key control?
If the goal is simply to rekey a knob or lever rather than build restricted key control, the Kaba Ilco 1539 Series key-in-knob/lever universal cylinder covers that ground, and the 1599 is a key-in-knob replacement cylinder. Those are standard-keyway parts, so they do not give you the patent-protected duplication control or the UL 437 drill and pick resistance the Medeco 2020000 carries. Note also that the Ilco parts are knob and lever cylinders, not padlock retrofits.
15) I want one key system across padlocks and doors. Can I do that with interchangeable cores instead?
Two different approaches. The Medeco 2020000 is a fixed retrofit cylinder that converts specific padlock bodies to a Medeco keyway, which is what you want when the padlocks are Abus 83KNK, American 3600/3700, or Master Pro Series and you are after patented key control. If your facility instead wants cores you can pull and swap without disassembly, look at an interchangeable core platform: the BEST 1CB Peaks 150 Series core, the drill-resistant patented BEST 1CDF 7-pin brass core, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam.
16) Do the Medeco 2020000 padlock cylinders come keyed alike so one key opens all my gates?
Order the Pinned option and specify your keying, and the cylinders can be set to a common key or brought onto an existing Medeco system. Ordering Sub-Assembled or Sub-Assembled No Slider instead means the cylinders arrive unpinned for your locksmith to key into the system on the bench, which is the usual route when the padlocks have to fall under an existing masterkey.
17) Is a Kaba Ilco 1539 knob and lever cylinder a substitute for the Medeco 2020000?
No. Both are key-in-knob/lever style cylinders, but the 2020000 is configured to retrofit Abus 83KNK, American 3600/3700, and Master 29, 6600, and 6700 Pro Series padlock bodies, and it carries UL 437 listing and ANSI/BHMA A156.30 in the M4 technology. The Kaba Ilco 1539 is a key-in-knob/lever universal cylinder for knob and lever locksets. Ordering the 1539 for a padlock retrofit puts the wrong cylinder in the shackle body.
18) My deadbolt needs a replacement cylinder, not my padlock. What is the right part?
The Medeco 2020000 retrofits padlock bodies, so a deadbolt takes a different cylinder. The Kaba Ilco 1549 is a key-in-deadbolt cylinder, and the 1599 is a key-in-knob replacement cylinder; the 1579 is the knob and lever cylinder made for Sargent hardware. Match the cylinder to the lock body you are servicing rather than carrying the padlock cylinder over.
19) Is a 5-pin core equivalent to the Medeco 2020000 for a padlock upgrade?
They are different pinning depths and different platforms. The 2020000 is a 6-pin cylinder, and the pin count is part of why it is specified for key control programs. The BEST 1C5 is a standard 5-pin cylinder core, and the BEST 1CDF is a 7-pin patented interchangeable core. Pin count has to match the keying system the facility already runs, and the 2020000 sits in a Medeco 6-pin system with Biaxial or M3 keyways.
20) What cylinder goes with an Adams Rite MS1847 deadlock if I also want a pull on the door?
The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, and the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock. The choice between them is how the pull anchors to the stile: trim plate mounting versus through-screws. The Medeco 2020000 is a padlock retrofit cylinder and does not serve a storefront pull.
21) Will the finish on the Medeco cylinder match the rest of my hardware?
Thirteen finishes are offered, from brass tones (605 Bright Brass, 606 Satin Brass, 609 Antique Brass) through bronze (611 Bright Bronze, 612 Satin Bronze, 613 Dark Bronze Oil-Rubbed, 624 Dark Bronze), nickel (20 Antique Nickel, 618 Bright Nickel, 619 Satin Nickel), chrome (625 Bright Chrome, 626 Satin Chrome), and 622 Flat Black. Since the cylinder face is the only part visible once it is in the padlock body, most fleet buyers pick 626 Satin Chrome or 626's brass counterpart to match the padlock shell rather than the door hardware.
22) Does the Medeco 2020000 have six pins or five?
Six. The 2020000 is a 6-pin cylinder, which gives more differs for a large key system and more pick resistance than the 5-pin cylinders common on standard padlocks. Several comparable parts in this class are 5-pin, such as the Adams Rite 4036 mortise cylinder and the 4025 cylinder pull.
23) What is a simpler cylinder to use where the padlock only needs to look locked and never actually key?
For a dummy or blank application, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the cylinder opening without keying. The Medeco 2020000 is a working 6-pin retrofit cylinder with UL 437 listing for drill and pick resistance and patent-protected key control, which is what you order when the padlock is actually being operated and audited.
