Medeco 12028006-09-G3 Cylinder Plug for Maxum Deadbolt, Biaxial 6-Pin G3 Keyway, Antique Brass

The Medeco 12028006-09-G3 is a precision-engineered cylinder plug designed as a direct replacement component for the Medeco Maxum Deadbolt (excluding Captive models). Featuring Medeco's renowned Biaxial locking technology with a 6-pin configuration and the proprietary G3 keyway, this plug delivers the high-security performance Medeco is known for in a commercial-grade replacement part. Finished in Antique Brass, it is suited for installations where both security integrity and aesthetic consistency are essential.

Key Features

  • Biaxial Technology: Incorporates Medeco's Biaxial cylinder design, which requires keys cut to both angle and depth, providing significantly enhanced pick and manipulation resistance compared to standard cylinders.
  • 6-Pin Configuration: Six-pin tumbler arrangement delivers a high level of key combination security, reducing the risk of unauthorized key duplication and unauthorized entry.
  • Proprietary G3 Keyway: The restricted G3 keyway is a Medeco-controlled profile, ensuring that key duplication is limited to authorized Medeco dealers and locksmiths for superior key control.
  • Maxum Deadbolt Compatibility: Designed specifically for the Medeco Maxum Deadbolt line (except Captive configurations), making it the correct OEM-specification replacement plug for that platform.
  • Antique Brass Finish: Antique Brass finish (finish code 09) allows for seamless aesthetic integration with existing Antique Brass door hardware installations.
  • Commercial-Grade Replacement Part: Classified as a commercial replacement part and accessory, engineered to restore full Medeco security performance to an existing Maxum Deadbolt assembly.
  • Medeco Parts and Accessories: Part of the official Medeco Tools, Parts and Accessories product line, ensuring genuine manufacturer specifications and compatibility.

Medeco 12028006-09-G3 – Frequently Asked Questions

1) Will the Medeco 12028006-09-G3 plug fit a Medeco Maxum Captive deadbolt?
No. The 12028006-09-G3 plug is built for the Medeco Maxum deadbolt line but Captive configurations are specifically excluded. If the deadbolt on the door is a Captive model, this is the wrong plug and you need the Captive-specific part instead.
2) What keys will work with this Medeco Maxum replacement cylinder plug?
It is cut for Medeco's Biaxial system in a 6-pin arrangement on the proprietary G3 keyway. Biaxial keys are cut to both angle and depth, so a standard flat-cut key will not operate it, and G3 is a restricted Medeco profile, meaning duplicates only come through an authorized Medeco dealer or locksmith. If your existing keys are a different Medeco keyway, this plug will not accept them.
3) Can this plug be keyed into our existing Medeco master key system?
Only if that system runs on the G3 keyway in a 6-pin Biaxial format. The plug is supplied on the restricted G3 profile, so a locksmith can pin it to your existing G3 Biaxial system and keep the key control program intact. A facility keyed on a different Medeco keyway needs a plug in that keyway instead.
4) Can a Corbin Russwin 253K66 rim cylinder plug be used in place of a Medeco 12028006-09-G3 on a Maxum deadbolt?
No. The Medeco 12028006-09-G3 is a cylinder plug built specifically for the Medeco Maxum Deadbolt (excluding Captive models), carrying Medeco Biaxial 6-pin construction and the restricted G3 keyway. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, so it is keyed to a different manufacturer's system and belongs in a rim cylinder housing rather than a Maxum deadbolt. Substituting it would break both the fit and the Medeco key control program.
5) What is the mortise-cylinder equivalent if the opening uses a mortise lock rather than a Maxum deadbolt?
The Medeco 12028006-09-G3 plug is made for the Maxum deadbolt platform, so it is not the part for a mortise body. For a mortise application, Corbin Russwin offers the 121K11-D2 and 121K11-L4, both Grade 1 1000 Series mortise cylinder plugs, differing in keyway designation. Those move the opening onto the Corbin Russwin keying system rather than Medeco Biaxial key control.
6) Do I need to replace the whole Medeco Maxum deadbolt, or just the cylinder plug?
If the deadbolt body and housing are sound and the problem is the key core (worn plug, rekey to a new keyway, damaged pin stack), the plug alone is the serviceable part. The 12028006-09-G3 is an OEM replacement plug that restores the Biaxial security of an existing Maxum assembly without pulling the deadbolt off the door. Replace the full deadbolt only if the housing or bolt itself is damaged.
7) Is a Medeco cylinder plug the same thing as a rim cylinder plug or a mortise cylinder plug?
No, and they are not interchangeable. The Medeco 12028006-09-G3 is the plug for a Maxum deadbolt cylinder. A rim device takes a different plug entirely, such as the Corbin Russwin 253K66 3000 Rim Cylinder Plug, and a mortise housing takes a mortise plug like the Corbin Russwin 121K11 1000 Series plug. Identify the cylinder format on the door first, then the keyway, then order the plug that matches both.
8) Does a replacement cylinder plug come with the retainer or clip?
The 12028006-09-G3 is the plug itself, a Maxum deadbolt replacement component. Retainers are separate parts in this category, for example the Corbin Russwin 219F88-8 Grade 1 Cylinder Plug Retainer on the Corbin side. If your service job needs a retainer, order it as its own line.
9) What is the difference between the Corbin Russwin 121K11-D2 and 121K11-L4 mortise plugs?
Both are Grade 1 1000 Series mortise cylinder plugs supplied as plug only, and both are catalogued with a cylinder function. They differ in the keyway suffix, D2 versus L4, so the choice is driven by which keyway your existing Corbin Russwin key system uses. Neither accepts a Medeco Biaxial key, which is what the Medeco 12028006-09-G3 is cut for.
10) Is a Corbin Russwin 219F88-8 cylinder plug retainer an alternative to ordering the Medeco 12028006-09-G3?
No, they do different jobs. The 219F88-8 is a Grade 1 cylinder plug retainer, a holding component, while the Medeco 12028006-09-G3 is the keyed plug itself, with the 6-pin Biaxial G3 pinning that determines which keys operate the Maxum deadbolt. If the key system is what you are restoring, the retainer will not do it.
11) What finish is the Medeco 12028006-09-G3 cylinder plug, and will it match our other door hardware?
Antique Brass, finish code 09 in the part number and shown as 609 - Antique Brass on the order. That is the only finish this plug is offered in, so if the visible cylinder face on your other openings is a bright or satin chrome, this plug will read differently against them.
12) Is this a residential or commercial-grade part?
Commercial. The plug is catalogued as a commercial high-security replacement component, and it is what locksmiths and security integrators use servicing Maxum deadbolts in offices, government buildings, healthcare, schools and multi-tenant properties where key control is part of the security program.
13) I need to match Antique Brass hardware on the rest of the door - does the comparable plug set offer that finish?
The Medeco 12028006-09-G3 is supplied in 609 Antique Brass, which is what lets it blend with existing Antique Brass trim on a serviced Maxum deadbolt. The Corbin Russwin comparables are identified by series and keyway rather than by an Antique Brass designation, so if finish matching at the cylinder face is part of the job, the Medeco plug is the one specified for it.
