Medeco 1202800T-18-DL – Frequently Asked Questions

1) Is this Medeco plug the M3 platform or the older Biaxial?
The 1202800T-18-DL is built to Medeco's M3 cylinder platform. If your existing deadbolt cylinder is Biaxial or original Medeco rather than M3, the plug and its pinning will not match your key system, so confirm the platform before you pull the cylinder apart.
2) What keyway and pin count does this Medeco cylinder plug come in?
DL keyway, 6-pin. Both have to match your existing system: the DL keyway determines which Medeco key blanks and key control records apply, and the 6-pin chamber count has to match the bitting on your keys. A 5-pin or different keyway Maxum system needs a different plug.
3) Can a Corbin Russwin 253K66 rim cylinder plug be used to rebuild a Medeco Maxum deadbolt?
No. The Medeco 1202800T-18-DL is a cylinder plug built for Medeco Maxum Deadbolt locks (except Captive configurations) on the M3 platform, with a 6-pin tumbler arrangement and the DL keyway, so it drops into that deadbolt without modification. The Corbin Russwin 253K66 is a 3000 rim cylinder plug - a plug for a rim cylinder in a different manufacturer's key system. The two are not interchangeable in either direction; a Maxum deadbolt rebuilt with anything other than the Medeco plug loses the M3 keyway and key control that the original cylinder was keyed to.
4) Can I rekey a Maxum deadbolt with this plug instead of buying a whole new cylinder?
That is exactly what it is for. Replacing the plug alone restores the 6-pin M3 architecture and DL keyway of the existing Maxum deadbolt without swapping the complete cylinder, which keeps the rest of the lock and the trim in place. It is a Medeco replacement part, so key control records for the DL keyway still apply.
5) I need a plug for a mortise or rim cylinder, not a Medeco deadbolt. What should I be looking at?
The Medeco 1202800T-18-DL is specific to the Maxum deadbolt and will not serve a mortise or rim housing. For mortise work, Corbin Russwin's 1000 Series plug-only parts (121K11-D2 and 121K11-L4) cover that cylinder type, and the 253K66 is the plug for a Corbin Russwin 3000 rim cylinder. If what failed is the retainer rather than the plug itself, the Corbin Russwin 219F88-8 is a cylinder plug retainer.
6) Does buying this plug give me a working cylinder, or do I still need pins and keys?
It is the plug component only, not a pinned and keyed cylinder. To put a Maxum deadbolt back in service you supply the pinning to your own DL keyway bitting and cut keys on the matching Medeco blanks. Standard practice for a high-security system is that the pinning and key cutting stay with an authorized dealer holding your key records.
7) What is the mortise-cylinder equivalent of the Medeco Maxum deadbolt cylinder plug?
If the opening takes a mortise cylinder rather than a Maxum deadbolt, the Medeco 1202800T-18-DL is the wrong part - it is built specifically for the Maxum Deadbolt (except Captive models). Corbin Russwin offers plug-only service parts for mortise cylinders in its 1000 Series, the 121K11-D2 and the 121K11-L4, which differ from each other by keyway designation. Those are Corbin Russwin key system parts, so they suit a door already on Corbin Russwin keying, not a Medeco M3 DL system.
8) I need the retainer that holds the plug in the cylinder, not the plug itself - which part is that?
The Medeco 1202800T-18-DL is the plug: the keyed core body that carries the 6-pin M3 tumbler stack and the DL keyway. A retainer is a separate small component. Corbin Russwin lists the 219F88-8 as a cylinder plug retainer, which is a Corbin Russwin part for Corbin Russwin cylinders. Ordering the Medeco plug will not supply a retainer, and a retainer will not restore a damaged or rekeyed plug - confirm which piece failed before ordering.
9) What finish does the 1202800T-18-DL plug come in, and will it match my existing deadbolt trim?
One finish only: 618 Bright Nickel. It shows at the keyface, so on a Maxum deadbolt finished in bright nickel or a polished chrome family it blends in. Against a bronze, oil-rubbed or brass deadbolt the plug face will read noticeably brighter.
10) Is this a commercial-grade part or a residential one?
Medeco classifies the 1202800T-18-DL as a commercial mechanical lock part. It is the plug locksmiths and in-house maintenance teams use servicing Maxum deadbolts in offices, healthcare, schools and municipal buildings where the master key system has to stay intact.
11) Is there a simpler option than the Medeco plug if I am standardizing a facility away from high-security keying?
The Medeco 1202800T-18-DL exists to preserve the M3 6-pin DL architecture and key control of a Maxum Deadbolt during service or rekeying, so it is the choice when the facility stays on Medeco keying. A facility moving to conventional Corbin Russwin keying would be working from that line instead - for example the 1000 Series mortise plug-only parts 121K11-D2 and 121K11-L4, or the 3000 rim cylinder plug 253K66, depending on whether the openings use mortise or rim cylinders. That is a change of key system and lock body, not a drop-in swap of the Maxum deadbolt plug.
