Medeco 1202900T-09-DL – Frequently Asked Questions

1) What exactly is the Medeco 1202900T-09-DL, and what lock does it go into?
It's a captive cylinder plug, the keyed core component that drops into a Medeco Maxum deadbolt. It is not a complete cylinder and not a complete deadbolt, so it will not work on its own. Medeco builds it specifically for the Maxum deadbolt housing, and the captive construction keeps the plug retained in the housing during operation. Order it when you are servicing, rekeying, or restoring an existing Maxum deadbolt rather than replacing the whole lock.
2) Will a DL keyway plug work with the keys already cut for my Medeco system?
Only if your existing system is on the M3 DL keyway. The 1202900T-09-DL is a 6-pin M3 plug in the DL keyway, and DL is a restricted keyway, so keys from a different Medeco keyway will not enter it. Check the keyway stamp or your key records against DL before ordering, otherwise you will be cutting new keys for that one opening.
3) I need a plug for a Corbin Russwin cylinder, not a Medeco. What should I be looking at?
This Medeco plug only fits Medeco Maxum hardware, so it is the wrong part for a Corbin Russwin lock. For Corbin Russwin mortise cylinders, the plug-only part is the 121K11 (offered in D2 and L4 keyway versions). For a Corbin Russwin 3000 rim cylinder, the matching plug is the 253K66. If what you actually broke was the retainer rather than the plug, the 219F88-8 cylinder plug retainer is the piece.
4) Can a Corbin Russwin 253K66 rim cylinder plug be used in place of a Medeco 1202900T-09-DL?
No. The Medeco 1202900T-09-DL is a captive cylinder plug engineered specifically for the Medeco Maxum Deadbolt with M3 technology and a 6-pin DL keyway, so it only serves Maxum deadbolt housings. The Corbin Russwin 253K66 is a 3000 Rim Cylinder Plug, meaning it is the plug for a rim cylinder body in the Corbin Russwin 3000 series. They are plugs for different cylinder bodies and different key systems, so neither drops into the other's housing.
5) I need a plug for a mortise cylinder, not a deadbolt - what should I look at instead of the Medeco 1202900T-09-DL?
The Medeco 1202900T-09-DL is built for the Maxum Deadbolt, so it is the wrong part for a mortise cylinder. For a mortise application, Corbin Russwin offers plug-only parts in the 1000 Series mortise cylinder line, such as the 121K11-D2 and the 121K11-L4 - both Grade 1 1000 Series mortise cylinder plugs, differing in keyway designation (D2 versus L4). Match the keyway letter to the key system already in the building.
6) Can I use this plug to replace a 5-pin Medeco cylinder?
No. This is a 6-pin configuration, so the pinning, key bitting, and key blank differ from a 5-pin cylinder. Swapping a 6-pin plug into a system keyed 5-pin means re-keying that opening rather than a like-for-like service. Match the pin count and the keyway before you pull the old plug.
7) Does buying this plug give me a rekeyable Medeco cylinder out of the box?
No. The 1202900T-09-DL is the plug component only, not a pinned and keyed cylinder assembly. A locksmith pins it to your system and cuts keys on the DL restricted keyway through authorized channels. If you want a drop-in keyed unit rather than a service part, a complete Medeco Maxum cylinder is the item to order instead.
8) We standardize our buildings on Medeco M3. Does this plug keep that system intact?
It does. The plug carries Medeco's M3 platform, so an opening serviced with it stays on the same high-security key control and pick and drill resistance as the rest of your M3 Maxum deadbolts, provided the keyway is DL and the pinning is 6-pin to match. That is the point of servicing with a factory plug rather than substituting a generic cylinder, which would break the master key system on that door.
9) Is the Corbin Russwin 219F88-8 an equivalent to the Medeco 1202900T-09-DL?
No - they do different jobs. The Medeco 1202900T-09-DL is the cylinder plug itself, the rotating keyed core for the Maxum Deadbolt in an M3 6-pin DL keyway. The Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer, the piece that holds a plug in place rather than the plug you cut keys to. If the keyed core is worn or being rekeyed, you need a plug; if the core is fine but not being held captive, you are looking at a retainer.
10) Do the Corbin Russwin 121K11 plugs give the same key control as the Medeco Maxum plug?
They are different key platforms. The Medeco 1202900T-09-DL carries Medeco M3 high-security technology with a restricted DL keyway and a 6-pin tumbler arrangement, which is what limits duplication to authorized channels. The Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs identified by their D2 and L4 keyways. A building standardized on Medeco M3 keys should stay with the Medeco plug; a building on Corbin Russwin keyways should stay within the 121K11 keyway options.
11) Is this a residential part or is it meant for commercial buildings?
Medeco classifies it as commercial. It is a replacement part in the Medeco tools, parts and accessories line, intended for offices, schools, healthcare, government buildings, retail and multi-tenant properties where restricted key control is in place. Nothing stops it going on a Maxum deadbolt in a residence, but the key control and duplication restrictions are what it is built around.
12) Which cylinder plug do I order if the finish has to match antique brass deadbolt trim?
The Medeco 1202900T-09-DL is supplied in 609 Antique Brass, a factory finish intended to match existing Maxum Deadbolt trim. The Corbin Russwin plug-only and plug retainer parts - 121K11-D2, 121K11-L4, 253K66 and 219F88-8 - are identified by cylinder series and keyway rather than a matching decorative finish, and they belong to Corbin Russwin cylinder bodies. For visible antique brass on a Maxum deadbolt, the 1202900T-09-DL is the part that keeps the appearance consistent.
