Medeco 12028006-11-G3 – Frequently Asked Questions

1) What keyway and pin count does this Medeco replacement plug come in?
Six-pin, Biaxial, cut for the G3 keyway. If your existing Medeco system runs a different keyway or a 5-pin cylinder, your current keys will not operate this plug and you would need one matched to your system.
2) Does this plug come keyed, or do I have to pin and key it myself?
It is a cylinder plug only, the plug body itself, not a complete keyed cylinder. A locksmith pins it to your existing Medeco G3 Biaxial system so the replacement stays on the same master key setup. Biaxial keys are cut at two angles as well as depths, so origination and duplication have to be done on Medeco-capable equipment.
3) I manage a building on a Medeco restricted key system. Can I just swap in a generic plug instead?
No. Restricted key control only holds if the plug is cut for the same patented keyway, in this case G3 Biaxial. A non-Medeco plug will not accept your keys and breaks the key control the system was installed for. This is the genuine OEM replacement part for that reason.
4) Can a Corbin Russwin cylinder plug be used to repair a Medeco Maxum deadbolt?
No. The Medeco 12028006-11-G3 is a genuine OEM plug built for the Medeco Maxum Deadbolt (except Captive configurations) with Biaxial 6-pin construction and the G3 restricted keyway, so it keys into an existing Medeco system. Corbin Russwin plugs such as the 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs on their own platform and keyways, and the 253K66 is a 3000 Series rim cylinder plug. They are plugs for Corbin Russwin cylinders, not Medeco deadbolt parts.
5) What finish is the Medeco 12028006-11-G3 plug, and will it match my existing deadbolt?
One finish only: 611 Bright Bronze. That is meant to match Bright Bronze Maxum hardware. If your deadbolt cylinder face is chrome, brass, or bronze-toned in another finish, the plug face will be visible and will not match.
6) I need a cylinder plug but my locks are Corbin Russwin, not Medeco. What should I be looking at?
This Medeco plug is specific to the Maxum deadbolt and will not go into Corbin Russwin hardware. For Corbin Russwin, the plug depends on the cylinder type: the 121K11 is the 1000 Series mortise cylinder plug (D2 and L4 keyway versions), the 253K66 is the 3000 Series rim cylinder plug, and the 219F88-8 is the plug retainer rather than the plug itself.
7) My Medeco deadbolt key turns hard and the plug is worn. Do I replace the whole deadbolt?
Not necessarily. Replacing just the plug restores the cylinder without pulling the deadbolt body, keeps the existing Maxum installation and hole prep intact, and keeps you on the same G3 Biaxial key system. Worn or damaged plug is exactly the case this part covers.
8) What is the difference between a cylinder plug and a cylinder plug retainer?
A cylinder plug is the rotating core that carries the pins and the keyway - the Medeco 12028006-11-G3 is that part for the Maxum Deadbolt, with Biaxial 6-pin construction and a G3 keyway. A retainer such as the Corbin Russwin 219F88-8 is the small piece that holds a plug in its shell; it contains no pins and no keyway. If the key turns but the plug is loose or backing out, the retaining part is the issue rather than the plug itself.
9) For a facility standardizing on restricted key control, does a standard plug work in place of the Medeco Biaxial plug?
No. The Medeco 12028006-11-G3 carries the G3 restricted keyway and Biaxial pinning, which requires keys cut at two angles in addition to depths and is what supports Medeco's key control program on the Maxum Deadbolt. Conventional plugs such as the Corbin Russwin 121K11-D2 and 121K11-L4 1000 Series mortise plugs operate on their own keyway sections and pin at depth only, so substituting one takes that opening off the Medeco key system.
10) Is this a commercial-duty part or is it for residential deadbolts?
Commercial-rated. It is used in offices, schools, healthcare, government buildings, and multi-tenant residential where key control matters, and it is equally correct on a high-security residential Maxum deadbolt since it is the same OEM part.
