Medeco 2000900T-26-DLT – Frequently Asked Questions

1) Does the Medeco 2000900 come with a tailpiece?
No. The 2000900 is supplied less tailpiece. Plan on carrying over the tailpiece from the Schlage B Series deadbolt you're retrofitting, or ordering the correct one separately. Medeco publishes over 100 cylinder and tailpiece configurations, so the matching part exists, but it is not in the box with this cylinder.
2) Is the Medeco 2000900 UL437 listed for drill and pick resistance?
Yes, UL 437 listed for drill and pick resistance, and it carries ANSI/BHMA A156.30 Level A for patent-protected key control and physical strength plus ANSI/BHMA A156.5 Grade 1 for heavy-use commercial applications. For a facilities spec that calls out high-security cylinders by standard, those three lines are what you cite.
3) What does Pinned versus Sub-Assembled mean when ordering a Medeco 2000900?
Three build states are offered. Pinned means the cylinder arrives keyed and ready to install. Sub-Assembled comes to you unpinned so a locksmith can pin it to an existing master key system in the shop. Sub-Assembled, No Slider is the same, minus the slider, for shops building the cylinder to their own key system. If you're a property manager or MRO buyer who wants it to work out of the box, order Pinned. If you're a locksmith keying to a site system, order one of the sub-assembled options.
4) Can I upgrade key control on Schlage deadbolts without replacing the whole lock?
That's the point of a retrofit cylinder like the Medeco 2000900. The deadbolt body, bolt, strike and door prep all stay; only the cylinder changes. You get UL 437 drill and pick resistance and patent-pending key control that restricts unauthorized duplication, at a fraction of the labour and cost of swapping every deadbolt in a building. For schools, healthcare and multi-tenant properties standardizing on restricted keys, it's the shortest path.
5) Is the Medeco 2000900 the right cylinder for a mortise lock or a rim exit device?
No, and this is the most common mis-order. The 2000900 is a key-in-knob/lever style retrofit cylinder for Schlage B Series deadbolts, not a mortise or rim cylinder. For a mortise lock you want a threaded mortise cylinder such as the Corbin Russwin 1000 Series in 1-1/2 inch with an A02 straight cam, or the 1070 in 1-1/4 inch with an A01 cloverleaf cam. For a rim exit device, a rim cylinder like the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam is the correct part.
6) What is the equivalent replacement cylinder for a Schlage B Series deadbolt if I do not need Medeco key control?
The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder also carrying a deadbolt function. Both cover deadbolt cylinder replacement without the patented key control system. The Medeco 2000900 is a 6-pin lazy motion cylinder built specifically for Schlage B Series deadbolts and supplied less tailpiece, and it is UL 437 listed for drill and pick resistance with ANSI/BHMA A156.30 Level A key control. Where a facility is standardizing on restricted keys, the Medeco path keeps duplication controlled; where the door only needs a working keyed deadbolt cylinder, the Ilco 1549 covers the function.
7) I need a Medeco cylinder for a Sargent knob or lever, not a Schlage deadbolt. What do I order?
The Medeco 2000900 is built for Schlage B Series deadbolts and will not serve a Sargent knob or lever prep. For that opening the Kaba Ilco 1579 is a knob and lever cylinder made for Sargent. Matching the cylinder to the lock manufacturer and to the prep type - deadbolt versus key-in-knob/lever - is what decides whether the cylinder seats and turns the retractor correctly.
8) Will a rim cylinder work in place of the Medeco 2000900?
No. A rim cylinder mounts through the door and drives an exit device or rim lock with a tailpiece behind the door - the Schlage 20-021 uses a vertical tailpiece cam and the Schlage 20-022 a horizontal tailpiece cam, and the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The Medeco 2000900 is a lazy motion cylinder for a Schlage B Series deadbolt. The two housings are not interchangeable; if the existing hardware is a rim exit device, order a rim cylinder, and if it is a B Series deadbolt, order the 2000900.
9) Our facility is standardized on interchangeable core. Is the Medeco 2000900 the right cylinder for us?
An interchangeable core program lets a facility rekey by pulling and swapping the core with a control key rather than repinning the cylinder. For that, 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, 150 Series; on the Schlage side the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and the 20-057-C is a full size interchangeable core in the C keyway, 643E Aged Bronze. The Medeco 2000900 is a conventional 6-pin cylinder for Schlage B Series deadbolts, pinned or supplied sub-assembled, with M3 and Biaxial technology and keyway options. Choose by whether the facility rekeys at the core or at the cylinder.
10) What do I use if the lock is a mortise lock rather than a deadbolt?
A mortise lock takes a threaded mortise cylinder driven by a cam, not the lazy motion deadbolt cylinder used on a Schlage B Series. The Corbin Russwin 1000 Grade 1 mortise cylinder is 1-1/2 inch with an A02 straight cam, the Corbin Russwin 1070 Grade 1 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the Corbin Russwin 1080 Grade 1 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 Schlage L cam. The Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security for doors 1/2 inch minimum thickness. Cam style and cylinder length have to match the lock case; length and cam are the two dimensions to confirm before ordering.
11) What are the alternatives to a Medeco retrofit cylinder for a deadbolt?
If restricted, patent-protected keying isn't the requirement, a standard replacement deadbolt cylinder is cheaper and simpler. The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the 1539 Series is a key-in-knob/lever universal cylinder also listed for deadbolt function. If your facility runs an interchangeable core system instead, a BEST 1C Series 5-pin core or the drill-resistant, patented 1CDF 7-pin core keeps you inside that platform. What none of those match is the Medeco 2000900's UL 437 listing and patent-pending key control, which is the reason to pay for it.
12) Is the Medeco 2000900 6-pin cylinder rated for commercial use?
Commercial is its classification, and the certifications back it: ANSI/BHMA A156.5 Grade 1 for consistent quality in heavy-use applications, plus A156.30 Level A. The cylinder components are precision-machined brass rather than cast or plated pot metal, which is what holds up to daily cycling on office, retail, warehouse and institutional openings.
13) What is the difference between the Medeco 2000900 and a key-in-lever cylinder like the Falcon A23161-05 G?
The Falcon A23161-05 G is a key in lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different, supplied with 2 cut keys. It goes into a lever lock chassis. The Medeco 2000900 is a lazy motion cylinder for a Schlage B Series deadbolt, supplied less tailpiece so the correct tailpiece can be selected for the deadbolt configuration, and it comes in Biaxial or M3 technology and keyway. The deciding factor is the host lock: a lever lockset takes the Falcon style cylinder, a B Series deadbolt takes the 2000900.
14) Is a 5-pin cylinder an acceptable substitute for the 6-pin Medeco 2000900?
They are different pinning depths and different key systems. The Medeco 2000900 is a 6-pin cylinder for commercial use, carrying UL 437 listing and ANSI A156.5 Grade 1. Among 5-pin cylinders, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security and the BEST 1C5 is a standard 5-pin cylinder core. A 6-pin cylinder gives more chambers for masterkeying depth and will not accept a 5-pin key bitting, so a facility running a 6-pin master system cannot key a 5-pin cylinder into it.
15) I need a cylinder for an aluminum storefront door. Does the Medeco 2000900 fit?
No. Narrow stile aluminum storefront takes cylinder pulls and deadlocks sized for the stile. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the Adams Rite 5017 wood door deadlock/deadlatch. The Medeco 2000900 fits Schlage B Series deadbolts, which is a bored deadbolt prep in a swinging door rather than a storefront stile.
16) How many pins does the Medeco 2000900 cylinder have and does that matter for masterkeying?
Six pins. The extra chamber over a 5-pin cylinder gives you more key differs and more room to build a master key system across a site, which is why 6-pin is the norm on commercial work while 5-pin shows up on lighter residential and storefront parts. If you're masterkeying to an existing Medeco system, order the sub-assembled version so your locksmith pins it to that system.
17) Can I match the finish of a Medeco 2000900 to residential hardware like the Emtek CY4?
The Emtek CY4 cylinder is sold as an each and sits in Emtek's parts line. The Medeco 2000900 is offered in 13 finish choices including 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 613 Dark Bronze Oil-Rubbed, 619 Satin Nickel, 622 Flat Black, 625 Bright Chrome and 626 Satin Chrome, so most common BHMA finish numbers on an existing opening can be matched. It is a commercial cylinder, which is the distinction that matters when a property has both residential-grade and commercial-grade doors in the same building.
18) The opening only needs the look of a keyed cylinder with no locking function. What should I order?
A dummy cylinder fills the prep without operating anything. The BEST 12E Series dummy rim cylinder is 1-5/32 inch in diameter and is made for that purpose. The Medeco 2000900 is a working 6-pin keyed cylinder for a Schlage B Series deadbolt with patented key control, so it is the wrong choice where no key operation is wanted.
