XT Dual-Tech Rim & Mortise

The Medeco XT Dual-Tech retrofit cylinder is designed for both accountability and rapid-entry applications.It combines two cylinder technologies – the Medeco XT electronic cylinder and the Medeco X4 mechanical cylinder– in one cylinder housing.

  • The Medeco XT electronic cylinder provides everyday access and gives the user full control and accountability by leveraging all of the features of Medeco’s powerful XT Web Manager software.
  • The Medeco X4 mechanical cylinder is ideal for local fire departments because it uses simple and familiar mechanical key technology, allowing rapid entry for inspections or emergency responses.
  • Both cylinders operate independently of one another so access is provided using either the XT Key or the X4 key.
  • Product can be ordered either pinned or sub-assembled for the Medeco X4 cylinder and includes two keys.

Medeco XT is a complete electronic locking system providing Controlled Access, Accountability, Physical Security, and System Management. More than just a way to protect your property, equipment and assets, Medeco XT is also a business tool that can lead to a substantial return on investment.

Medeco 490423 G – Frequently Asked Questions

1) What is the Medeco XT Dual-Tech cylinder, and why does it take two different keys?
It's a retrofit cylinder that puts two independent locking technologies in one housing: the Medeco XT electronic cylinder and the Medeco X4 mechanical cylinder. The XT side handles everyday credentialed access with audit and scheduling; the X4 mechanical side is there so a fire department or emergency responder can get in with a conventional key. Neither side depends on the other, so the opening works with either the XT key or the X4 key. That's the whole point of the dual-tech design, and it's why you order it for sites that need both accountability and rapid entry.
2) Which cylinder formats does the Medeco XT Dual-Tech come in - do I order rim or mortise?
Four formats are offered: a rim cylinder, a 1-1/4 inch mortise cylinder with Medeco X4, a 1-1/4 inch mortise cylinder for Arrow/Best, and a 1-3/4 inch mortise cylinder. Order rim if you're replacing the cylinder in a rim exit device; order mortise if it threads into a mortise lock body, and match the length to what's in the door now. The Arrow/Best version is the one to take when the existing mortise hardware is Arrow or Best. All four are 626 satin chrome.
3) Do I have to run wiring or power to the door for a Medeco XT cylinder?
No wiring, no door cords, no power supply. The XT cylinder is powered entirely by the key when it's inserted, which is why it retrofits into an existing mortise or rim prep without any door or frame modification for cabling. That's the practical difference between this and a wired electronic lock: you get audit and access control on openings where pulling power was never going to happen, including gates, cabinets, and remote sites.
4) My building is keyed on Best interchangeable cores - can I put Medeco XT Dual-Tech on those doors?
There's a 1-1/4 inch mortise version built for Arrow/Best hardware, so the mortise openings are covered. The rest of the building can stay on your existing core program: BEST 1C Series standard 5-pin cores, the 1CB 150 Series interchangeable core, or the 1CDF drill resistant 7-pin patented core all remain the way to key the openings you aren't converting. Typical approach is to put the dual-tech cylinders only on the doors that need audit or emergency-responder access and leave the rest mechanical.
5) What is the difference between the 1-1/4 inch and 1-3/4 inch mortise Medeco XT Dual-Tech cylinders?
Length. A mortise cylinder threads into the lock body, and the length has to bring the cam to the right depth for the lock case and the door thickness plus any trim. Thicker doors and thick escutcheons need the 1-3/4 inch; standard mortise lock preps usually take the 1-1/4 inch. Measure what's coming out of the door before you order, because a cylinder that sits proud is a security problem and one that sits short won't throw the lock.
6) How do I handle a lost key on a Medeco XT system without rekeying the whole building?
Blacklist it. The lost or stolen key goes on the unauthorized key list, and the cylinders stop accepting it, so there's no pulling cylinders and no repinning across the site. Keys also carry their own operating and expiration schedule, so a contractor credential can be set to die on a date instead of relying on someone handing it back. The mechanical X4 side is separate, so an X4 key that goes missing is handled the traditional way.
7) What rim cylinder can replace a Medeco XT Dual-Tech rim cylinder on an exit device when only mechanical keying is required?
The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Match the tailpiece orientation to what the exit device chassis takes. The Medeco XT Dual-Tech rim cylinder differs in that it runs the XT electronic cylinder and the X4 mechanical cylinder independently in one housing, so the door can be opened with either the XT key or the X4 key; the Schlage rim cylinders are mechanical only.
8) What mortise cylinder fits an aluminum storefront deadlock instead of a Medeco XT Dual-Tech?
For an Adams Rite MS1847 deadlock or deadlatch in an aluminum storefront, the Adams Rite 4036 mortise cylinder is a Grade 1 four-thousand-thirty-six series cylinder rated for doors 1/2 inch minimum thickness, and the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are made for use with the MS1847 deadlock and deadlatch. The Medeco XT Dual-Tech is also a Grade 1 cylinder, but it is supplied in 1-1/4 inch and 1-3/4 inch mortise formats and a rim format, so confirm the storefront stile accepts one of those before choosing it over the Adams Rite parts.
9) What is a straight mechanical equivalent to a Medeco XT Dual-Tech mortise cylinder if electronic audit is not needed?
If the opening only needs mechanical keying, a Corbin Russwin 1070 Grade 1 series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam covers the same 1-1/4 inch mortise prep that the Medeco XT Dual-Tech offers in a 1-1/4 inch mortise cylinder. The difference is scope: the Medeco XT Dual-Tech combines the XT electronic cylinder with the Medeco X4 mechanical cylinder in one housing, so it carries key-powered access control and audit alongside the mechanical key, while the Corbin Russwin 1070 is a mechanical housing only. Choose by whether the door needs the electronic side at all.
10) For a facility standardizing on interchangeable core, what should be used instead of a Medeco XT Dual-Tech cylinder?
An interchangeable core program is a different architecture. The BEST 1CB Peaks 150 series interchangeable core cylinder and the BEST 1CDF drill resistant patented interchangeable core 7-pin brass 150 series cylinder let a facility rekey by pulling and swapping cores with a control key. The Medeco XT Dual-Tech is a retrofit cylinder that puts an XT electronic cylinder and an X4 mechanical cylinder in one housing, with lost or stolen keys blacklisted in software rather than by pulling a core. Decide based on whether credential control lives in the core or in the key.
11) Is a Medeco XT Dual-Tech cylinder the right choice for an Arrow or Best prepped mortise lock, or is there another option?
The Medeco XT Dual-Tech is made in a 1-1/4 inch mortise cylinder specifically for Arrow and Best, so it drops into that prep while carrying both the XT electronic cylinder and the X4 mechanical cylinder. If the opening only needs mechanical keying in a BEST core program, the BEST 1CB Peaks 150 series interchangeable core cylinder is the mechanical route. The choice comes down to whether that door needs the 2000 audit events and key blacklisting the Dual-Tech provides.
12) Can a Medeco XT Dual-Tech cylinder be used outdoors?
Yes, it's built for indoor or outdoor use with a stainless steel shell, and it's called out as weather resistant. The housing is also drill and tamper resistant. That makes it usable on perimeter gates, exterior doors, and utility enclosures rather than only conditioned interior openings.
13) How many audit events does the Medeco XT cylinder store, and how do I get them out?
The cylinder holds 2000 audit events in non-volatile memory, so the record survives with no power at the door. The key itself carries up to 5,000 events and access rights for up to 5,000 cylinders, and it moves the data back to XT Web Manager software. Programming is done at the key, with stand-alone, network, web, and mobile options. Lost or stolen keys get blacklisted so they stop working at the cylinder, which is how you rekey a site without pulling hardware.
14) How often do the XT keys need charging?
The XT key runs on a rechargeable battery good for 1,500 to 1,800 openings per charge when the cylinder unlock time is set to 0.8 seconds. Nothing at the door needs a battery, since the key supplies all the power. For a route with a lot of stops that usually means a charge cycle measured in weeks rather than days, but the number that governs it is openings, not calendar time, so size the key count to your busiest carrier.
15) Is the Medeco XT Dual-Tech cylinder heavy enough for a high-traffic commercial opening?
It's a Grade 1, heavy duty commercial cylinder with a brass substrate and a stainless steel shell. Grade 1 is the highest ANSI/BHMA commercial rating, which is what a hospital, school, or municipal facility spec will typically call for. Not a residential part.
16) I need a plain replacement mortise cylinder for a Schlage L9000 mortise lock, not an electronic one - what should I look at?
For a straight mechanical swap on an L9000, the Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, with the A01 Schlage L cam is built for those locks. If your lock takes a conventional (non-interchangeable core) cylinder, the Corbin Russwin 1000 Grade 1 series 1-1/2 inch with an A02 straight cam or the 1070 Grade 1 1-1/4 inch 6-pin housing with an A01 cloverleaf cam are the usual choices. Cam style is the part people get wrong, so match the cam to the lock body.
17) Is a Schlage 20-057 FSIC rim cylinder a substitute for a Medeco XT Dual-Tech rim cylinder?
They serve different jobs. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys, and the 20-057-C is a full size interchangeable core cylinder in a C keyway with a 643E aged bronze finish. Both are mechanical FSIC housings. The Medeco XT Dual-Tech rim cylinder carries the XT electronic cylinder for everyday access with audit through XT Web Manager plus the X4 mechanical cylinder for rapid entry, in one housing. If the requirement is audit trail and key blacklisting, the FSIC rim cylinders do not do that work.
18) What should be used on a wood door deadlock where a Medeco XT Dual-Tech does not suit the prep?
The Adams Rite 4026 five pin tumbler cylinder pull is built for the Adams Rite 5017 wood door deadlock and deadlatch, which is the prep to specify when the opening is a wood door running that lock. The Medeco XT Dual-Tech is supplied as 1-1/4 inch and 1-3/4 inch mortise cylinders and a rim cylinder, so it fits openings prepped for standard mortise or rim cylinder formats rather than the 5017 wood door pull prep.
19) Which cylinder replaces a Medeco XT Dual-Tech on a knob or lever lock instead of a mortise or rim opening?
A key-in-knob or key-in-lever opening takes a different cylinder body. The Kaba Ilco 1539 series is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key in lever cylinder in the RU/T series 6-pin G keyway, keyed different with 2 cut keys. The Medeco XT Dual-Tech is offered in 1-1/4 inch and 1-3/4 inch mortise and rim formats, so it goes into mortise or rim prepped hardware, not a knob or lever chassis.
20) What is a simpler mortise cylinder option than a Medeco XT Dual-Tech for a low-traffic back-of-house door?
The Detex MC65 is a mortise cylinder with a Schlage C keyway, 1-1/8 inch, 6-pin, commercial grade, which covers a standard keyed opening with no electronics. The Medeco XT Dual-Tech is heavy duty Grade 1 with a stainless steel shell rated for indoor or outdoor use and drill and tamper resistance, and it stores 2000 audit events. Where a door does not need accountability or exterior exposure, the MC65 is the plainer mortise cylinder; where it does, the Dual-Tech carries those features.
21) What rim cylinder housing pairs with a longer tailpiece if a Medeco XT Dual-Tech rim cylinder does not reach?
The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece from the 3000 series, which is the option when the device requires that tailpiece reach. The Medeco XT Dual-Tech rim cylinder is a retrofit format carrying both the XT electronic and X4 mechanical cylinders. Confirm the tailpiece length the exit device or rim lock requires, then pick the housing that meets it.
22) Can a BEST 1C5 core be swapped into a Medeco XT Dual-Tech cylinder?
No. The BEST 1C5 is a standard 5-pin cylinder core from the standard and premium cores line, meant to drop into a BEST interchangeable core housing. The Medeco XT Dual-Tech is a self-contained retrofit cylinder housing that carries the Medeco XT electronic cylinder and the Medeco X4 mechanical cylinder, and it is ordered either pinned or sub-assembled for the X4 side with two keys. A BEST core is not part of that assembly.
23) Which cylinder suits a residential-style opening rather than a Medeco XT Dual-Tech?
The Emtek CY4 cylinder is sold each as a parts item and suits decorative residential-style hardware. The Medeco XT Dual-Tech is a commercial, heavy duty Grade 1 cylinder in a brass substrate, offered in 626 satin chrome across its mortise and rim formats. For a commercial opening under an access control program, the Dual-Tech is the one specified; for residential trim, the Emtek CY4 is the fit.
24) What replaces a Medeco XT Dual-Tech on a deadbolt opening?
For a keyed deadbolt, the Kaba Ilco 1549 series is a key-in-deadbolt cylinder with a deadbolt function. The Medeco XT Dual-Tech comes in 1-1/4 inch and 1-3/4 inch mortise cylinders and a rim cylinder, formats intended for mortise locks and rim-mounted devices, so a deadbolt with its own cylinder body takes the 1549 instead.
