American Lock APTC12 – Frequently Asked Questions

1) Which American Lock padlocks does the APTC12 cylinder plug fit?
The APTC12 is a factory service part for American Lock A700, A1000 and A6000 Series padlocks. It drops into those bodies without modification, so it is the plug to order when you are rebuilding or re-keying one of those three series. It is not a plug for other American Lock families or other brands.
2) Is the APTC12 a 5-pin or 6-pin plug?
Five pins. The APTC12 uses a 5-pin tumbler configuration, so it has to be pinned to a 5-pin key bitting. If the padlock you are servicing was set up on a 6-pin system, this plug will not carry that bitting and you need the 6-pin service plug for that series instead.
3) Can a Corbin Russwin 253K66 rim cylinder plug be used to rebuild an American Lock A1000 padlock?
No. The American Lock APTC12 is a 5-pin cylinder plug built as a service part for A700, A1000 and A6000 Series padlocks, so it seats in the padlock body those series use. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, meaning it is the plug for a rim cylinder that mounts through a door and drives a rim exit device or auxiliary lock. The two are not interchangeable housings; for a padlock rebuild stay with the APTC12.
4) Does the APTC12 come keyed, or do I have to pin it myself?
It is a cylinder plug only, not a complete keyed cylinder. A locksmith pins it to the keyway and bitting the site already runs, which is how these service parts are used to bring a padlock back onto an existing master key system. Budget for pins, springs and a key blank on your side.
5) Can I use a plug like this to re-key padlocks instead of buying new locks?
That is exactly what it is for. Replacing the plug in an A700, A1000 or A6000 padlock lets a property manager or locksmith change key control on a lock that is otherwise sound, rather than pulling and replacing the whole padlock. Useful where you have a fleet of the same series across a site and only the keying needs to change.
6) I need a cylinder plug for a mortise or rim door cylinder, not a padlock. What should I look at instead?
The APTC12 will not help you there, it is a padlock plug. For door cylinders, Corbin Russwin's 1000 Series mortise cylinder plugs (121K11-D2 and 121K11-L4) cover mortise applications, and the 253K66 covers 3000 Series rim cylinders. If a plug is walking out of the housing rather than failing, the Corbin Russwin 219F88-8 is a cylinder plug retainer.
7) Is the Corbin Russwin 219F88-8 cylinder plug retainer a replacement for the APTC12?
No, they are different pieces of a cylinder. The Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer, the small component that holds a plug in its shell. The American Lock APTC12 is the plug itself, the 5-pin keyed core used in A700, A1000 and A6000 Series padlocks. If the key turns but the plug is loose or backing out you are looking at a retainer; if the pinning or keyway is the issue you need the plug.
8) We standardize padlocks across a facility and also maintain Corbin Russwin door cylinders. Do plugs carry across?
They do not. The American Lock APTC12 is a commercial 5-pin plug dedicated to A700, A1000 and A6000 Series padlocks. Corbin Russwin plugs are housing-specific in the same way: 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs, and 253K66 is a 3000 rim cylinder plug. Plan parts stock by lock family, keeping APTC12 for the padlock fleet and the matching Corbin Russwin plug for each door cylinder type.
9) Is the APTC12 rated for commercial and industrial use, or just light duty?
American Lock lists the APTC12 as commercial-grade. It is used in office buildings, warehouses and industrial plants, schools, government facilities, retail, healthcare and multi-tenant residential, which is the same environment the host padlocks serve.
10) Is the APTC12 a genuine American Lock part or an aftermarket copy?
Genuine. The APTC12 is an American Lock factory service part from the Cylinders and Keys parts line, so the plug is built to the same dimensions as what came in the padlock originally. That matters when the lock has to keep working with an existing key system and strike of service keys.
