Medeco 1202900T-05-DL – Frequently Asked Questions

1) Will the Medeco 1202900T-05-DL plug fit any Medeco cylinder, or only the Maxum deadbolt?
It is built for the Maxum Deadbolt platform specifically. The 1202900T-05-DL is an OEM Medeco plug dimensioned for Maxum deadbolt cylinders, so treat it as a drop-in service part for those cylinders rather than a general-purpose plug for mortise, rim, or knob cylinders.
2) What keyway and pin count does this Medeco Maxum deadbolt plug come in?
DL keyway with a 6-pin tumbler stack. That means it only accepts Medeco DL key blanks, so if the building's key system runs a different Medeco keyway this plug will not key into it. Confirm the existing cylinders are DL before you pull the old plug.
3) Is this the whole cylinder or just the plug?
Just the plug, the rotating core that carries the pins and accepts the key. It is sold as a replacement part, not a complete cylinder or a complete deadbolt, so you are reusing the existing Maxum cylinder shell, cam, and hardware.
4) Can a Corbin Russwin 253K66 rim cylinder plug be used to repair a Medeco Maxum deadbolt?
No. The Medeco 1202900T-05-DL is a cylinder plug built specifically for the Medeco Maxum Deadbolt platform with a Captive M3 6-pin configuration and DL keyway, so it keys to Medeco blanks and fits Medeco Maxum cylinder housings. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, meaning it belongs in a rim cylinder body rather than a Maxum deadbolt. They are not interchangeable parts; repairing a Maxum deadbolt means staying with the Medeco plug.
5) What is the equivalent part if the job is a mortise cylinder rather than a deadbolt?
For a mortise cylinder repair, the Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs, supplied as plug only, with the two part numbers differing by keyway designation (D2 and L4). The Medeco 1202900T-05-DL is instead a Maxum Deadbolt plug in a Captive M3 6-pin DL keyway, so it serves the deadbolt cylinder rather than a mortise body.
6) What does the Captive M3 designation mean on this cylinder plug?
Captive means the plug stays retained in the cylinder housing while you service it, so the pins and components are less likely to spill during a rekey or swap. M3 identifies the Medeco generation the plug belongs to, which matters because it determines which key blanks and pinning the cylinder works with.
7) I need a plug for a Corbin Russwin cylinder, not Medeco. What should I look at?
Medeco plugs do not cross into other manufacturers' cylinders. For Corbin Russwin, the 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plug-only parts, and the 253K66 is the plug for 3000 Series rim cylinders. If you are chasing the retainer rather than the plug itself, the Corbin Russwin 219F88-8 is the plug retainer.
8) Our facility is standardizing keying across doors. How does the Medeco Maxum plug differ from the Corbin Russwin 121K11 plugs in keying terms?
The Medeco 1202900T-05-DL comes in the DL keyway with a 6-pin Captive M3 stack, so it ties into Medeco key blanks and keyway-restricted key control programs. The Corbin Russwin 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs supplied in D2 and L4 keyways respectively. A facility standardizing on one key system should match the plug keyway to the system already in place rather than mixing families.
9) Is the 1202900T-05-DL a residential or commercial-duty part?
Commercial. Medeco lists this plug for commercial use, and it is the part locksmiths and facility maintenance crews use for cylinder service on offices, schools, healthcare, and government openings running Maxum deadbolts.
10) Does using a genuine Medeco plug matter, or can I rebuild with a generic core?
It matters for key control. Medeco's restricted keyways and pick resistance depend on OEM geometry, and the DL keyway here is part of a restricted key control system. Dropping in a non-Medeco core breaks that security architecture on the opening.
11) Is the Medeco 1202900T-05-DL suitable for residential service calls, or is there a lighter-duty option?
The Medeco 1202900T-05-DL is designated for commercial use as an OEM replacement part for Medeco Maxum deadbolt cylinders. Among comparable plug parts, the Corbin Russwin 121K11-D2 and 121K11-L4 mortise plugs and the 253K66 rim cylinder plug are likewise commercial cylinder components. Choice between them comes down to the cylinder body in the door, not the duty level.
