Medeco 12029006-12-G3 – Frequently Asked Questions

1) Will this Medeco plug work in my existing Medeco key system, or do I need matching keys?
The plug is cut for the G3 keyway in a Captive Biaxial 6-pin configuration. It only works in a system already keyed to G3 Biaxial. If your building runs a different Medeco keyway or a non-Biaxial (original or M3) platform, the keys won't enter or the pin geometry won't lift correctly. Check the keyway stamp on a current key before ordering.
2) Is this a plug only, or does it come as a complete cylinder?
Plug only. It's the rotating core that carries the pins and keyway, sold as a replacement part, not a full cylinder housing and not a complete deadbolt. Pins, springs, and keys are a separate matter and are set up by whoever keys the system.
3) Can a Corbin Russwin cylinder plug be used to repair a Medeco Maxum deadbolt?
No. The Medeco 12029006-12-G3 is a replacement cylinder plug engineered specifically for the Medeco Maxum deadbolt, with Captive Biaxial 6-pin geometry and the proprietary G3 keyway. Corbin Russwin plugs such as the 121K11-D2 and 121K11-L4, which are 1000 Series mortise cylinder plugs, are built to Corbin Russwin cylinder dimensions and keyways and will not accept Medeco Biaxial pins or G3 keys. Keep Medeco service parts on Medeco cylinders and Corbin Russwin parts on Corbin Russwin cylinders.
4) What does the Captive Biaxial 6-pin design actually do for security?
Biaxial pins have to be both lifted to the right height and rotated to the right angle, which is what gives Medeco its pick resistance. The G3 keyway is proprietary, so blanks are restricted and keys can't be duplicated at a hardware counter. The captive construction keeps the plug retained in the lock body during operation and service. That combination is why facilities with strict key duplication policies specify it.
5) What finish does the Medeco Maxum deadbolt cylinder plug come in?
One finish only: 612 Satin Bronze, clear coated. On a Maxum deadbolt the plug face is the visible part at the keyway, so it needs to match the rest of the deadbolt trim. If your existing hardware is satin chrome or bright brass, this plug will read as a different color at the key face.
6) I need a cylinder plug but my locks aren't Medeco. What else is out there?
Medeco plugs are platform-specific, so a Maxum plug is no help on another brand. For Corbin Russwin openings, the 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs (the D2 and L4 denote different keyways), and the 253K66 is a 3000 Series rim cylinder plug. If what actually failed is the retainer rather than the plug, the Corbin Russwin 219F88-8 is the Grade 1 cylinder plug retainer. Match the plug to the cylinder body you already have, not the other way round.
7) Can I use this plug to rekey a Maxum deadbolt into a new master key system?
Yes, that's a normal use. Swapping the plug is how you move a Maxum deadbolt onto a different G3 Biaxial keying scheme without replacing the whole deadbolt, which is why it shows up in restricted master key programs in schools and multi-tenant buildings. The pinning itself is done by a locksmith with Medeco Biaxial pins; the plug is the carrier.
8) I need a plug for a rim cylinder, not a deadbolt. Is the Medeco 12029006-12-G3 the right part?
No. The Medeco 12029006-12-G3 is dimensioned for the Medeco Maxum deadbolt cylinder. A rim cylinder uses a different plug; the Corbin Russwin 253K66 is a 3000 Series rim cylinder plug and is the correct part family for a Corbin Russwin rim application. Confirm the cylinder housing type, mortise, rim, or deadbolt, before ordering any plug.
9) What is the difference between a cylinder plug and a cylinder plug retainer?
They are different parts. The Medeco 12029006-12-G3 is the plug itself, the rotating core that carries the pins and the G3 keyway inside the Maxum deadbolt cylinder. A retainer, such as the Corbin Russwin 219F88-8 cylinder plug retainer, is the small holding component that keeps a plug seated in its cylinder body. If the keyway or pinning is the problem you need a plug; if the plug is backing out or loose you are looking for a retainer, and the 219F88-8 is a Corbin Russwin part, not a Medeco one.
10) For a facility standardizing on restricted keys, how does the Medeco 12029006-12-G3 differ from a Corbin Russwin 121K11 plug?
The Medeco 12029006-12-G3 carries the Captive Biaxial 6-pin platform and the proprietary G3 keyway, which is the mechanism Medeco uses to restrict key duplication and hold key control across a commercial master key program. The Corbin Russwin 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs supplied in Corbin Russwin keyways, so a facility running them is working inside the Corbin Russwin keying system instead. Choose the plug that matches the keyway system already issued to your building.
11) Is this Medeco part meant for residential or commercial use?
Commercial. It's specified for offices, schools, healthcare, government buildings, retail, industrial plants, and multi-tenant properties running centralized key management. Nothing stops it going on a residential Maxum deadbolt, but the reason to buy it is key control across a facility.
