American Lock AME-A30MK 2KEY – Frequently Asked Questions
1) Will the American Lock A30MK fit a standard hasp opening, and how much shackle clearance does it give?
The A30MK has a 1-1/2 inch wide aluminum body with a 1/4 inch diameter shackle that stands 1 inch tall and spans 3/4 inch between the legs. That 3/4 inch inside clearance is what has to clear your hasp staple or chain link, and the 1/4 inch shackle diameter has to pass through the hole in the hasp. On a self-storage latch or a locker hasp that is usually fine; on a heavy gate chain with thick links, the 1 inch shackle height will not reach.
2) What does the MK in American Lock A30MK actually mean for my keying?
MK means keyed different under a master key. Every lock in the order gets its own change key, and one master key opens them all. That is the setup a self-storage operator or facility manager wants: the tenant or technician carries a key that opens only their unit, and the office carries the master. If you want every lock to open on the same key with no master above it, the A30KA is the keyed alike version; A30KAMK is keyed alike under a master.
3) Can a locksmith rekey the A30MK padlock later?
No. The A30MK uses a non-rekeyable 5-pin APTC12 cylinder, so the keying is set at the factory and cannot be changed in the field. Order it keyed to the master system you want up front. If a key is lost on a non-rekeyable lock, the lock gets replaced rather than repinned, which is why buyers on these usually order spare keys with the lock.
4) I need a padlock on the same key system as my Sargent or Schlage building cylinders. Is the A30MK the right pick?
No. The A30MK is a sealed factory-keyed lock on American Lock's own 5-pin APTC12 cylinder, so it cannot be brought onto a building master key system. For that you want a padlock that accepts your house cylinder or core: the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless shackle, and the Sargent 758 and 858 are standard padlocks in the same family. The Schlage KS23D/KS23F brass padlock with a 5/16 inch shackle is another route if your building is on Schlage.
5) What is the closest aluminum-body padlock to the American Lock A30MK if I need the same 1-1/2 inch body and 1/4 inch shackle?
The ABUS 74/40 insulated safety padlock is the nearest match on those two dimensions: it also carries a 1-1/2 inch body width and a 1/4 inch shackle diameter. The differences are in construction and cylinder. The A30MK is a solid aluminum body with a non-rekeyable 5-pin APTC12 cylinder, factory keyed different under a master key. The ABUS 74/40 is an insulated safety padlock built on a 6-pin cylinder. If the driver is a corrosion-resistant aluminum body on a lockout or outdoor opening, the 74/40 covers the same footprint; if the driver is master keying into an existing American Lock system, stay with the A30MK.
6) I need a padlock I can rekey in the field instead of ordering factory keyed - what should I use in place of the A30MK?
The A30MK is a non-rekeyable padlock, so its 5-pin APTC12 cylinder is factory keyed and cannot be re-pinned on site. If field rekeying or core swapping is the requirement, the Sargent 60-858-2 is the direct alternative - it is a removable core padlock with a 2 inch stainless steel shackle, so the core can be pulled and changed as your keying changes. Note the body material differs: the A30MK is solid aluminum, and the Sargent shackle is stainless rather than the A30MK chrome-plated 1/4 inch shackle.
7) I do not need master keying - is there a simpler version of the A30MK aluminum padlock?
Yes. Within the same solid aluminum non-rekeyable family, the A30 (A30KD) is keyed different without a master, and the A30KA is keyed alike so one key opens every lock in the order. The A30MK is the keyed different plus master keyed version, and A30KAMK is keyed alike under a master. The body and shackle are the same across them - 1-1/2 inch aluminum body, 1/4 inch shackle - so the choice is purely the keying scheme. The A31 and A32 numbers carry the same keying options on taller shackles.
8) Can I mix the American Lock A30MK with ABUS or Sargent padlocks on the same master key system?
No. The A30MK is factory keyed on a non-rekeyable 5-pin APTC12 cylinder, and that keyway and master system is specific to American Lock - it does not cross to the ABUS 72 Series, 74 Series or 76 Series, or to the Sargent 758 and 858 Series bodies, or to the Schlage 20 Series KS23D/KS23F. To keep one key across a site, standardize on the A30, A30KA, A30MK and A30KAMK family and order them under the same factory keying instruction.
9) Is an aluminum body padlock the right choice for outdoor or washdown areas?
Aluminum is the reason to pick the A30. The solid aluminum body will not rust, and the shackle is chrome plated for corrosion resistance, so it holds up in wet, salty, or chemical washdown areas where a plated steel padlock blooms rust. Trade-off: aluminum is softer than a hardened steel body, so for high-attack exterior gates you want a steel or stainless body instead. A stainless option in the same class is the Medeco 521 G8R, which has a solid stainless steel body.
10) How many keys come with each A30MK lock, and can I order it with fewer?
Key count is a choice you make on the order. The standard is 2 keys per lock, and you can also take 1, 3, or 4 keys per lock, or 0 keys per lock. Zero keys is what large master keyed systems order when the keys are cut and issued centrally, or when locks are being added to an existing system that already has keys in circulation.
11) Can I get the A30MK padlock with a chain attached for gates or equipment?
Yes. Each A30MK can be ordered with a #40 sash chain, 9 inches (229mm) long, zinc plated, or with no chain at all. The chain version is what people use so the lock stays tethered to the gate, the panel, or the piece of equipment instead of going in a pocket and disappearing. Note the chain is a retainer at 9 inches, not a securing chain for wrapping a gate post.
12) What is the difference between the American Lock A30, A31 and A32 aluminum padlocks?
They are the same solid aluminum non-rekeyable family in different sizes, and each comes in four keying setups: keyed different (A30/A31/A32), keyed alike (KA), keyed different under a master (MK), and keyed alike under a master (KAMK). The A30 is the 1-1/2 inch body with a 1 inch tall, 1/4 inch shackle. Pick the number for the body and shackle you need, then the suffix for how the facility is keyed.
13) Is the A30MK suitable as a lockout/tagout safety padlock?
It is not built for that role. The A30MK is a grey aluminum keyed padlock intended for self-storage units, lockers and manufacturing environments, and its master keying is the opposite of what lockout requires. For LOTO use an anodized safety padlock like the ABUS 72/30 (1-1/4 inch body, 3/16 inch shackle) or the insulated ABUS 74/40 with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body.
14) The A30MK shackle is only 1 inch tall - what padlock has a longer shackle for a thicker hasp or chain?
The A30MK shackle clearance is 1 inch tall, which suits a standard hasp or a self-storage latch but will not close over stacked links or a deep hasp. For more clearance, the Sargent 60-858-2 carries a 2 inch stainless steel shackle, and the Sargent 82-856 is a non-key-retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle. Both move you off the aluminum body of the A30MK, so if you are locking in a corrosive or washdown area, consider instead pairing the A30MK with the #40 sash chain option, 9 inches long and zinc plated, which is offered on the lock itself.
15) Is a brass-body padlock like the Sargent 858 an equivalent substitute for the American Lock A30MK?
They are not interchangeable choices, mainly on body material and key retention. The A30MK is a solid aluminum body in grey, chosen for corrosion resistance in manufacturing and self-storage environments, and its cylinder is non-rekeyable. The Sargent 858 is a non-key-retaining padlock with a stainless steel shackle in a US4 satin brass finish, and the companion Sargent 758 is the key-retaining version of the same body - key retaining means the key will not come out while the lock is open, which is the usual requirement for lockout and tool-crib control. Decide on whether you need the key trapped in the open lock and whether brass or aluminum suits the environment.
16) What is a smaller or lighter padlock than the A30MK for lockout tags and small lockers?
The ABUS 72/30 is the lighter option - an anodized aluminum safety padlock with a 1-1/4 inch body width and a 3/16 inch shackle diameter, against the A30MK 1-1/2 inch body and 1/4 inch shackle. The smaller shackle passes through tighter hasps and lockout devices. The ABUS T84MB/30 Nautic goes smaller still, with a 13/64 inch shackle diameter and a 1-17/64 inch body, and adds a black sleeve over the body. Keep in mind the A30MK is the one of these that is factory master keyed, so if the locks have to fall under an existing master, the smaller ABUS bodies are a different key system.
17) For a wet or coastal outdoor gate, is the aluminum A30MK the right pick or should I use a stainless body?
The A30MK is built for corrosive settings with a solid aluminum body and a chrome shackle, and it is a commercial-duty lock. For direct weather exposure on a gate, the Medeco 521 G8R is the weather-tight alternative, built on a solid stainless steel body and supplied less the pop-out cylinder so the cylinder is specified separately. The ABUS 76/40 is another outdoor-oriented option, a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter - the same shackle diameter as the A30MK - where the plastic jacket protects the finish it is locked against.
18) If I want higher-security key control than the A30MK master key system, what padlock steps up?
The A30MK uses a non-rekeyable 5-pin APTC12 cylinder factory keyed different under a master, with Edge key control available. For a patented high-security cylinder instead, the Medeco 5260 is a 52 Series brass body padlock with M3 key technology and a 7/16 inch shackle diameter in satin chrome, and the Sargent 82-856 runs the KESO system in a 2 inch by 2 inch brass case. If the requirement is audit trail rather than mechanical key control, the Medeco 54515G XT is an electronic indoor/outdoor padlock with a 5/16 inch shackle diameter, non-key retaining, supplied with cylinder. All three are larger-shackle brass or electronic locks rather than the 1-1/2 inch aluminum body of the A30MK.
19) How does the A30MK ship for a large property or storage facility rollout?
Packed 6 per shelf pack and 24 per master carton, so multi-unit orders come in clean multiples for a facility rollout. The body is grey aluminum and it is rated as a commercial product, which is the level self-storage, lockers and plant environments buy at.
