Medeco 12029006-09-G3 – Frequently Asked Questions

1) What exactly does the Medeco 12029006-09-G3 include, and is it a complete cylinder?
It is the plug only, not a complete cylinder. The 12029006-09-G3 is the OEM replacement cylinder plug for the Medeco Maxum Deadbolt, supplied in a captive 6-pin Biaxial configuration with the G3 keyway and a 609 Antique Brass finish. You reuse the existing cylinder housing; this restores the plug inside it. It is a service part for locksmiths, not a drop-in lock.
2) Will this Medeco plug fit any Medeco cylinder, or only the Maxum deadbolt?
It is built as a direct-fit replacement for the Medeco Maxum Deadbolt cylinder housing, and that is the application it is specified for. Medeco uses different plug lengths and shapes for mortise, rim and key-in-knob cylinders, so do not plan on dropping this one into a non-Maxum housing.
3) Can I key this plug to my existing Medeco master key system?
Only if your system runs the G3 keyway. This plug is cut for the G3 keyway and takes Biaxial pinning, where key cuts are made at two different angles as well as different depths. If your building is keyed in another Medeco keyway or in standard (non-Biaxial) Medeco, the key will not enter or will not rotate. G3 blanks are restricted to authorized Medeco dealers, which is the point of the keyway for key control programs.
4) Is a 6-pin Medeco plug going to match my 5-pin cylinder?
No. The 12029006-09-G3 is a six-pin plug, so the chamber count has to match the housing and the bitting on your keys. A 5-pin Maxum cylinder needs a 5-pin plug; putting a 6-pin plug behind 5-pin keys leaves an unpinned chamber and a key that will not turn.
5) Can a Corbin Russwin 253K66 rim cylinder plug be used to service a Medeco Maxum deadbolt?
No. The Medeco 12029006-09-G3 is a captive Biaxial 6-pin plug with the G3 keyway, built as a direct-fit OEM replacement for the Maxum deadbolt cylinder housing. The Corbin Russwin 253K66 is a 3000 series rim cylinder plug, so it is keyed and sized for a Corbin Russwin rim cylinder, not a Medeco deadbolt. Plugs are not interchangeable across manufacturers or cylinder formats - rebuild a Maxum with the Medeco part.
6) What is the equivalent plug-only part if the door has a Corbin Russwin mortise cylinder instead of a Medeco Maxum?
For a Corbin Russwin 1000 series mortise cylinder, the plug-only service parts are the 121K11-D2 and 121K11-L4, which differ by keyway designation (D2 and L4). The Medeco 12029006-09-G3 serves the same role - a replacement cylinder plug sold without the housing - but is cut for Medeco's G3 keyway and the Maxum deadbolt. Match the plug to the cylinder brand and keyway already in the opening.
7) What does captive mean on a Medeco cylinder plug?
Captive construction means the plug is retained in the cylinder housing rather than being free to pull out of the front. It stays held during operation and while you are servicing the lock, so rekeying procedure differs from a standard removable plug. If your Maxum was built with a non-captive plug, order that version instead.
8) Will the Antique Brass finish on this plug match my existing deadbolt trim?
The plug is finished 609 Antique Brass, which is the factory finish used to match Maxum Deadbolt hardware in that same finish. If the rest of your deadbolt is 626 satin chrome or 605 bright brass, the plug face will read as a different color at the keyway, so order the plug in the finish your rose and thumbturn already carry.
9) I need a plug for a Corbin Russwin mortise cylinder, not a Medeco. What should I be looking at?
The Medeco Maxum plug will not serve a Corbin Russwin cylinder. For Corbin Russwin, the 1000 Series mortise cylinder plug-only parts are 121K11-D2 and 121K11-L4, differing by keyway. If you are servicing a Corbin Russwin rim cylinder instead, the 253K66 3000 rim cylinder plug is the corresponding part, and 219F88-8 is the plug retainer if that is the piece that failed.
10) Can a general maintenance tech install a Medeco Maxum cylinder plug, or does it need a locksmith?
This is a locksmith-level part. It ships as a plug for qualified locksmiths and security professionals to service Maxum cylinders, and Biaxial pinning requires angled-cut key blanks and Medeco-specific tooling to pin correctly. An MRO tech without Medeco tools and G3 blanks cannot complete the job on site.
11) I only need the piece that holds the plug in - is that the same as ordering the Medeco 12029006-09-G3?
No. The Medeco 12029006-09-G3 is the cylinder plug itself, the rotating core carrying the Biaxial 6-pin stack and G3 keyway. A retaining component is a separate item - for example, the Corbin Russwin 219F88-8 is a cylinder plug retainer rather than a plug. If the plug is intact and only the retention hardware failed, you are looking for a retainer for that cylinder line, not a replacement plug.
12) Our facility standardizes on one keyway across all doors - how does choosing the Medeco Maxum plug affect that versus a Corbin Russwin cylinder plug?
The Medeco 12029006-09-G3 uses the proprietary G3 keyway, which restricts key blanks to authorized Medeco dealers and supports a controlled key system for commercial and institutional buildings. Corbin Russwin plug-only parts are ordered by their own keyway designation instead - the 121K11 mortise plug is offered as D2 and as L4. Because the keyways are brand-specific, a facility standardizing on Medeco G3 should stay within Medeco plugs rather than mixing cylinder brands in the same master key program.
13) Is a mortise cylinder plug a valid substitute for a deadbolt cylinder plug?
No. The Medeco 12029006-09-G3 is built to the Maxum deadbolt cylinder housing as a captive plug, meaning it is retained in that specific housing. A mortise cylinder plug such as the Corbin Russwin 121K11-D2 is dimensioned for a threaded mortise cylinder body, a different cylinder format entirely. Confirm which cylinder type the door actually carries before ordering a plug.
14) Is this a residential replacement part or a commercial one?
Medeco classifies the Maxum plug as commercial-grade, and it is the part used in office buildings, schools, healthcare, government facilities, banks and multi-tenant residential where a key control program is already in place. A single-family homeowner with no Medeco key system will get nothing out of it, because the G3 blanks are dealer-restricted.
