Medeco 1012040T-26-DLT – Frequently Asked Questions

1) Can I upgrade to a Medeco high security key without replacing the whole deadbolt?
That is exactly what the 1012040 is for. It swaps the cylinder in an existing Kwikset single cylinder deadbolt (Powerbolt excepted), so the lock body, bolt and strike stay in the door and the opening never gets re-prepped. For a property manager or MRO buyer with dozens of Kwikset deadbolts already hung, it moves the doors onto restricted Medeco keys one cylinder at a time.
2) Is the Medeco 1012040 a UL 437 listed high security cylinder?
Yes on the M4 platform: Medeco M4 key-in-knob cylinders are UL 437 listed for drill and pick resistance, and carry ANSI/BHMA A156.30 Level A for key control and physical strength plus ANSI/BHMA A156.5 Grade 1. That combination is what usually satisfies a government, healthcare or education spec calling for a certified high security cylinder.
3) What do I have to specify when ordering a Medeco 1012040 cylinder?
Three choices decide the part number. Keyway technology: Biaxial or M3. Pinning: Pinned, Sub-Assembled, or Sub-Assembled with No Slider. Finish: 13 options, from 605 Bright Brass and 606 Satin Brass through 613 Dark Bronze Oil-Rubbed, 619 Satin Nickel, 622 Flat Black, 626 Satin Chrome and 20 Antique Nickel. A locksmith keying to an existing system orders sub-assembled and pins it to the master; a one-off replacement usually goes out pinned.
4) Will Medeco keys on this cylinder stop tenants from copying keys at the hardware store?
Key control is the point of the 1012040. It runs patent-protected Medeco key blanks, which restricts unauthorized duplication, and the cylinder is certified to ANSI/BHMA A156.30 Level A, the level that covers patent-protected key control along with physical strength. For multi-tenant residential or a retail back door, that is the difference between changing cylinders at every turnover and simply collecting the keys.
5) I have a rim exit device, not a Kwikset deadbolt. Is this the right cylinder?
No. Despite the rim-type description, the 1012040 is cut for Kwikset single cylinder deadbolts and its tailpiece suits that lock. For a standard rim exit device, the Schlage Commercial 20-021 rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal cam is the correct part, and the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece is another rim option.
6) My doors have mortise locks, not deadbolts. Does this Medeco cylinder work in a mortise lock?
It does not. The 1012040 is a Kwikset deadbolt retrofit, and a mortise lock takes a threaded mortise cylinder with a cam. For those openings look at the Corbin Russwin 1000 Grade 1 mortise cylinder at 1-1/2 inch with an A02 straight cam, the 1070 Grade 1 6-pin mortise housing at 1-1/4 inch with an A01 cloverleaf cam, or the Detex MC65 1-1/8 inch 6-pin mortise cylinder. Match the cam to the lock brand before ordering.
7) The opening is a mortise lock, not a Kwikset deadbolt. What cylinder replaces the Medeco 1012040 there?
A mortise lock takes a threaded mortise cylinder with a cam, which is a different body than the Kwikset deadbolt retrofit the 1012040 covers. Among mortise options, the Corbin Russwin 1000 Grade 1 Series is a 1-1/2 inch mortise cylinder with an A02 straight cam, the Corbin Russwin 1070 Grade 1 Series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the Corbin Russwin 1080 Grade 1 Series is a 1-1/2 inch LFIC 6-pin mortise cylinder for Schlage L9000 mortise locks with an A01 Schlage L cam. The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in Schlage C keyway. Cam style and cylinder length have to match the lock case.
8) The door is a narrow stile aluminum entrance with a deadlock, not a bored deadbolt. Which cylinder goes there?
The Medeco 1012040 seats in Kwikset single cylinder deadbolts and bored type auxiliary deadlatches and deadlocks, not in narrow stile deadlock systems. For an Adams Rite MS1847 deadlock or deadlatch, the Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws. For a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 is the five pin tumbler cylinder pull. Those combine the cylinder and the pull in one assembly rather than dropping a cylinder into an existing lock body.
9) What is the closest equivalent to the Medeco 1012040 if the deadbolt being rekeyed is not a Kwikset?
The Medeco 1012040 is built specifically to retrofit Kwikset single cylinder deadbolts except the Powerbolt, so it is the wrong body for another maker's deadbolt. For a key-in-deadbolt cylinder that is not tied to Kwikset, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, and the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder that also carries a deadbolt function. Both are separate cylinder families rather than variations of the Medeco body, so the tailpiece and cam arrangement must be matched to the lock being opened.
10) Is a Schlage 20-021 rim cylinder a substitute for a Medeco 1012040?
No. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and its companion 20-022 is the same cylinder with a horizontal tailpiece cam. Those are standard rim cylinders for rim exit devices and rim locks. The Medeco 1012040 is a Lazy Motion Rim Type cylinder made to drop into Kwikset single cylinder deadbolts except the Powerbolt. The words rim cylinder appear on both, but the tailpiece motion and the hardware they seat in are different, so one will not stand in for the other.
11) We want interchangeable cores across the building instead of pinned cylinders. What do we buy instead of the Medeco 1012040?
The 1012040 ships pinned, sub-assembled, or sub-assembled with no slider, all of which are conventional cylinder builds rather than removable cores. For a core that pulls with a control key, the BEST 1CB Peaks 150 Series interchangeable core and the BEST 1CDF drill resistant patented 7-pin brass 150 Series core are interchangeable core cylinders, and the BEST 1C Series standard 5-pin core is the conventional core in that family. On the full size side, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is the FSIC core itself in C keyway, 643E Aged Bronze. Moving to cores changes the housings the openings need, so it is a hardware decision, not a like-for-like cylinder swap.
12) What is the difference between Medeco Biaxial and M3 on this Kwikset retrofit cylinder?
They are two different Medeco keyway platforms, and the one you order has to match the keys and any existing master system on the site. Biaxial and M3 are both offered on the 1012040. Pick the platform your Medeco key system is already built on; mixing platforms on the same facility means two key rings.
13) What else can I use to replace a Kwikset deadbolt cylinder if I don't need Medeco key control?
Kaba Ilco makes key-in-deadbolt replacement cylinders for exactly this job: the 1549 Series is the key-in-deadbolt cylinder, and the 1539 Series is a universal key-in-knob/lever cylinder listed for deadbolt function. Those are the straightforward swap when the requirement is a working keyed cylinder rather than a restricted, UL 437 listed one. The 1012040 is what you order when the spec calls for patent-protected keys and drill and pick resistance.
14) Should I order the Medeco cylinder pinned or sub-assembled?
Pinned means it arrives keyed and ready to install, which suits a property manager replacing a single cylinder. Sub-Assembled ships for the locksmith to pin into an existing Medeco master key system on site, and Sub-Assembled No Slider is the version supplied without the slider for shops building the cylinder themselves. If the building already runs a Medeco system, the sub-assembled options are what keep the new door on the same master.
15) Is a brass Medeco cylinder tough enough for a heavy traffic commercial entrance?
The 1012040 uses machined brass components and is certified to ANSI/BHMA A156.5 Grade 1, the heavy-duty commercial cylinder level, and it is classed for commercial rather than residential use. That is the durability level facility buyers standardize on for entrances that get keyed dozens of times a day.
16) I need to standardize a mixed building on one Medeco key. Does this cylinder help?
It covers the Kwikset deadbolt portion of that job. Medeco builds over 100 cylinder designs and tailpiece configurations across knob and lever cylindrical locksets, padlocks, and bored auxiliary deadlatches and deadlocks, so a facility can bring different hardware onto one Medeco key system by changing cylinders instead of locks. Keep the keyway platform, Biaxial or M3, the same across every cylinder you order for the site.
17) Is an interchangeable core a better choice than this Medeco cylinder for a large facility?
Different maintenance model. The 1012040 is a fixed cylinder: rekeying means pulling and repinning it. An interchangeable core lets a facility manager swap a core with a control key in seconds, which is why schools and hospitals with high turnover often specify one. BEST supplies that route with the 1C Series standard 5-pin core, the Peaks 1CB 150 Series core, and the 1CDF drill resistant patented 7-pin brass 150 Series core; Schlage offers the 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. The trade-off is that going IC usually means changing the lock hardware, not just the cylinder.
18) What is a simpler cylinder than the Medeco 1012040 when patented key control is not required?
The 1012040 is ordered in Biaxial or M3 technology and keyway, which are Medeco's restricted, patent-protected key systems with utility patent pending key control that limits unauthorized duplication. Where a facility does not need restricted keys, plainer 5-pin cylinders exist: the BEST 1C Series is a standard 5-pin core, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder, and the Falcon A23161-05 G is a 6-pin key-in-lever cylinder in the G keyway supplied keyed different with 2 cut keys. Those trade the restricted keyway for open key duplication, which is the deciding factor rather than the pin count.
19) Can a BEST 12E dummy rim cylinder be used where a Medeco 1012040 would go?
No. The BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter, meaning it fills the hole and carries no key operation. The Medeco 1012040 is a keyed 6-pin cylinder that turns a Kwikset single cylinder deadbolt, with the Medeco key control behind it. A dummy is used to close off an unused prep or match the look of a keyed side, so it is a visual match rather than a functional substitute.
20) We are standardizing key-in-knob and lever cylinders across a mixed hardware building. How does the Medeco 1012040 fit alongside other brands?
The 1012040 sits in Medeco's Key-in-Knob/Lever line, which retrofits knob and lever cylindrical locksets, padlocks, and bored type auxiliary deadlatches and deadlocks, with the 1012040 body itself aimed at Kwikset single cylinder deadbolts except the Powerbolt. Where other lock brands are in the same building, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the 1539 is a universal key-in-knob/lever cylinder. Each brand's openings need the cylinder body and tailpiece cut for that lock, so a mixed building is standardized by keyway and keying rather than by one part number.
21) Does the Medeco 1012040 fit a rim exit device the way a Corbin Russwin 3070 does?
No. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, the long flat tailpiece a rim exit device needs to reach through the door and drive the device. The Medeco 1012040 uses a Lazy Motion Rim Type body sized for Kwikset single cylinder deadbolts except the Powerbolt. The tailpiece length and the hardware behind the door are what separate them, so a rim exit device calls for the exit device housing rather than the Kwikset retrofit.
22) Which cylinder should be specified when the job calls for ANSI Grade 1 and a UL437 listing?
The Medeco 1012040 is a UL 437 listed cylinder on the M4 platform, carrying ANSI/BHMA A156.30 Level A and ANSI/BHMA A156.5 Grade 1, and it is built from machined brass. Among the mortise alternatives, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness, and the Corbin Russwin 1000, 1070, and 1080 are Grade 1 Series mortise cylinders. Those meet the grade line on a drawing; the drill and pick resistance listing and the A156.30 Level A key control are what set the Medeco apart in the specification.
23) Can I match the Medeco cylinder to the oil rubbed bronze hardware already on my doors?
613 Dark Bronze Oil-Rubbed is one of the 13 finishes, and 624 Dark Bronze is offered separately if the existing trim is the flatter dark bronze rather than the oil-rubbed. The full range also covers 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 611 Bright Bronze, 612 Satin Bronze, 618 Bright Nickel, 619 Satin Nickel, 622 Flat Black, 625 Bright Chrome, 626 Satin Chrome and 20 Antique Nickel, so the cylinder face can be matched rather than left as an odd ring on the door.
24) Will a Medeco 1012040 match the finish on hardware we already run, or do we have to change brands to get a match?
The 1012040 is ordered in 13 finishes including 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 613 Dark Bronze Oil-Rubbed, 619 Satin Nickel, 622 Flat Black, 624 Dark Bronze, 625 Bright Chrome, 626 Satin Chrome, 20 Antique Nickel, 611 Bright Bronze, 612 Satin Bronze, and 618 Bright Nickel. Comparable cylinders are far narrower on finish - the Schlage 20-057-C FSIC core, for example, is a 643E Aged Bronze core. Where a fleet of doors has to look consistent, the finish range is usually the deciding factor rather than the cylinder body.
