American Lock ABTC1U – Frequently Asked Questions

1) Does the American Lock ABTC1U blade tumbler cylinder come with keys?
No keys are supplied with the ABTC1U. It ships less keys, so a locksmith can key it into an existing American Lock master key system or you can order keys separately. Plan on cutting or ordering keys as part of the job, because out of the box the cylinder cannot be operated.
2) What exactly is the ABTC1U part, a whole lock or just the cylinder?
It is a cylinder plug only, an American Lock service part used to replace a worn or damaged blade tumbler cylinder in compatible American Lock hardware. You are buying the locking core component, not a padlock or a complete lock body.
3) Can a Corbin Russwin 253K66 rim cylinder plug be used in place of an American Lock ABTC1U?
No. The ABTC1U is an American Lock blade tumbler cylinder plug supplied less keys, made as an OEM service part for compatible American Lock hardware, so it is dimensioned to that housing. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, which is a plug for a rim cylinder body on a door and a different platform entirely. Use the ABTC1U where an American Lock cylinder is being serviced and the 253K66 where a Corbin Russwin 3000 rim cylinder is.
4) What is the mortise cylinder equivalent if the opening needs a mortise lock rather than American Lock hardware?
For a mortise application, look at the Corbin Russwin 121K11-D2 or 121K11-L4, both Grade 1 1000 Series mortise cylinder plug only parts. The ABTC1U is a blade tumbler cylinder plug built as an American Lock service part for compatible American Lock hardware, not a mortise cylinder. The two 121K11 parts differ from each other by keyway designation, D2 versus L4.
5) Is a blade tumbler cylinder different from the pin tumbler cylinders I normally stock?
Yes. The ABTC1U uses a blade tumbler mechanism rather than pin stacks, so it keys and services differently from the conventional mortise and rim plugs most shops carry, such as the Corbin Russwin 121K11-D2 mortise cylinder plug or the 253K66 3000 rim cylinder plug. If your opening takes a standard mortise or rim cylinder, one of those is the part you want, not this one.
6) I need to rekey rather than replace the core. Should I buy the ABTC1U?
Buy it when the cylinder itself is worn, damaged or you want a fresh keying start on compatible American Lock hardware. Since it arrives less keys, it is equally a rekey path: install the new plug and key it to the system you already run. If the existing plug is sound and you only want new bitting, rekeying what is in the lock may be the cheaper route.
7) What else might I need when replacing a cylinder plug on a commercial lock?
Plan for keys, since the ABTC1U comes with none, and for whatever retaining hardware the host lock uses. On other brands that retainer is a separate line item, for example the Corbin Russwin 219F88-8 cylinder plug retainer. Confirm what your American Lock body needs before the service call so you are not making a second trip.
8) Is the Corbin Russwin 219F88-8 a substitute for the ABTC1U cylinder plug?
It is not. The 219F88-8 is a Grade 1 cylinder plug retainer, the retaining component that holds a plug in place, not the plug itself. The American Lock ABTC1U is the blade tumbler cylinder plug, supplied less keys, for replacing a worn or damaged cylinder in compatible American Lock hardware. If the plug is what failed, the retainer will not restore the lock.
9) We standardize on Corbin Russwin keyways across the campus - does that rule out the ABTC1U?
For openings fitted with Corbin Russwin hardware, the 121K11-D2 and 121K11-L4 Grade 1 1000 Series mortise cylinder plugs keep you on that platform. The American Lock ABTC1U is supplied less keys specifically so it can be keyed to an existing master key system, so it can be brought into a facility keying scheme where the hardware being serviced is American Lock. The distinction is the hardware the plug seats in, not the keying program.
10) Is this cylinder suitable for heavy commercial and institutional use?
It is rated commercial, and the intended uses run to industrial and warehouse facilities, schools, healthcare, government buildings, multi-tenant properties and retail. For a property manager standardizing service parts across a portfolio of American Lock hardware, it is the maintenance cylinder to stock.
