American Lock AME-A31KD 2KEY – Frequently Asked Questions

1) Will the American Lock A31 padlock fit a hasp with a 3/4 inch opening?
The A31 gives you 3/4 inch of shackle clearance width and 1-1/2 inch of shackle height, on a 1/4 inch diameter shackle. So a hasp staple up to 1/4 inch thick with a 3/4 inch clear opening takes it. If your hasp loop is thicker than 1/4 inch or the eye is wider than 3/4 inch, you need a heavier padlock, not this one.
2) Can a locksmith rekey an American Lock A31?
No. The A31 uses a non-rekeyable 5-pin APTC12 cylinder, so the keying is set at the factory and cannot be changed in the field. If you need to rotate keying later, this is the wrong lock. The upside is there is no rekeying kit to stock and the cylinder can be factory keyed to your requirement up front.
3) Is the A31 keyed different, or will all the locks in my order open with one key?
The A31 (A31KD) is keyed different, meaning each lock ships on its own key. For a self-storage row or a fleet of gates where one key should open everything, order the A31KA keyed alike version instead. American Lock also builds the A31MK (keyed different, master keyed) and A31KAMK (keyed alike, master keyed) if you need a management key over the top.
4) Which padlock holds up outdoors near salt air or washdown chemicals?
The A31 is built for it: a solid aluminum body that does not rust like steel, plus a chrome plated shackle for extra corrosion resistance. American Lock lists it for harsh outdoor conditions and manufacturing environments. Aluminum is lighter than a brass or stainless body, so if the opening needs real attack resistance rather than weather resistance, look at a stainless body lock such as the Medeco 521 G8R weather-tight padlock.
5) I need padlocks that take my facility's interchangeable core. Is the A31 an option?
No. The A31 is a fixed, non-rekeyable cylinder, so it will not accept a small format or large format interchangeable core and cannot be brought into an existing SFIC system. For core-based standardization look at a removable core padlock such as the Sargent 60-858-2, which uses a removable core and a 2 inch stainless steel shackle.
6) What is the closest aluminum-body padlock to the American Lock A31 if I need the same 1/4 inch shackle diameter?
The ABUS 74/40 insulated safety padlock matches the A31 on both key dimensions: a 1/4 inch shackle diameter and a 1-1/2 inch body width, the same figures the A31 carries. The difference is construction and cylinder. The A31 is a solid aluminum body with a non-rekeyable 5-pin APTC12 cylinder, so keying is set at the factory, while the 74/40 is an insulated body on a 6-pin cylinder. For a lockout or electrical application where the insulated body matters, the 74/40 is the one to spec; for corrosive outdoor and manufacturing use where a solid aluminum body and chrome shackle are the point, stay with the A31.
7) The American Lock A31 cannot be rekeyed. What padlock should I use instead if I want to key it into my existing system?
The A31 uses a non-rekeyable 5-pin APTC12 cylinder that is keyed at the factory, so it will not accept your keyway in the field. For system integration, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, which lets you drop in the core your facility already uses. The Sargent 82-856 in the KESO series is another route, a non-key-retaining padlock with a 2 inch by 2 inch brass case and stainless shackle. Either of those is the direction for a master-keyed facility; the A31 is for openings you want sealed to a factory key set.
8) My spec calls for a thicker shackle than the American Lock A31. What options step up?
The A31 carries a 1/4 inch shackle diameter with a 1-1/2 inch shackle length. Two peers go heavier: the Schlage KS23D/KS23F brass padlock at a 5/16 inch shackle diameter, and the Medeco 5260 in the 52 series, a brass body padlock with a 7/16 inch shackle diameter in satin chrome. The Medeco 54515G is also at 5/16 inch and is an electronic indoor/outdoor padlock rather than a mechanical one. Confirm your hasp eye clears the larger diameter before you switch, since a 7/16 inch shackle will not pass a hasp drilled for 1/4 inch.
9) We want audit trail and access scheduling on our padlocks. Does the American Lock A31 do that?
No. The A31 is a mechanical padlock with a non-rekeyable 5-pin APTC12 cylinder that is factory keyed, so it opens on a cut key and nothing more. For electronic credential control on an exterior point, the Medeco 54515G XT is the electronic indoor/outdoor padlock in the set, non-key-retaining with a 5/16 inch shackle diameter and supplied with cylinder. Facilities often run both, the electronic unit on the gates that need a record and the A31 on the storage and locker points that do not.
10) What is the difference between the American Lock A30, A31 and A32?
They are the same solid aluminum non-rekeyable family, separated by shackle height. The A31 carries a 1-1/2 inch tall, 1/4 inch diameter shackle on a 1-1/2 inch wide body. The A30 is the shorter shackle in the line and the A32 the longer. Pick by how much clearance your hasp or chain link needs; the body, cylinder and finish are otherwise the same across the three.
11) How many keys come with each A31 padlock, and can I order it with no keys at all?
Keys per lock are an order option on the A31. Standard is 2 keys per lock, and you can also specify 1, 3, 4, or 0 keys per lock. The zero-key option is what facilities buy when they already hold the key blanks or want the keys shipped separately to a security manager rather than in the box with the locks.
12) Can I get the A31 padlock with a chain so it stays attached to the gate?
Yes. The A31 can be ordered with a #40 sash chain, 9 inches (229mm) long, zinc plated, or with no chain at all. The chain option keeps the lock tethered to a gate, locker, or electrical panel so it does not walk off or get set down in the dirt while the opening is open.
13) How does the A31 compare to an ABUS aluminum safety padlock for lockout use?
Body and shackle sizes are the closest thing to compare. The A31 is a 1-1/2 inch wide aluminum body with a 1/4 inch shackle. The ABUS 72/30 anodized aluminum safety padlock is narrower at 1-1/4 inch body with a 3/16 inch shackle, so it slips into tighter lockout hasps. The ABUS 74/40 insulated safety padlock matches the A31 at 1-1/2 inch body and 1/4 inch shackle but runs a 6-pin cylinder and an insulated body for electrical work.
14) I need a smaller, lighter aluminum padlock than the American Lock A31 for tagging valves. What else is there?
The ABUS 72/30 anodized aluminum safety padlock is the smaller option: a 1-1/4 inch body width on a 3/16 inch shackle diameter, against the A31's 1-1/2 inch body and 1/4 inch shackle. Both are aluminum-bodied. Drop to the 72/30 where the hasp eye or tag point is tight and the load is light; keep the A31 where you want the heavier 1/4 inch chrome shackle and the solid aluminum body for corrosive conditions.
15) Is a brass padlock like the Sargent 758 a substitute for the American Lock A31?
They are not interchangeable in the way most buyers assume. The A31 is a solid aluminum body, 1-1/2 inch wide, with a 1/4 inch chrome shackle, built for corrosive outdoor and manufacturing environments. The Sargent 758 is a key-retaining padlock in a US4 satin brass finish, and the key-retaining action means the key cannot be withdrawn while the lock is open, which matters on doors where you do not want a key walking away. The Sargent 858 is the non-key-retaining counterpart with a stainless steel shackle in the same US4 satin brass. If the driver is corrosion and body material, the A31 is the aluminum answer; if the driver is key retention behavior, look at the 758 or 858 pair.
16) For a wet or coastal exterior application, how does the American Lock A31 compare to a stainless steel padlock?
The A31 handles weather through material choice: a solid aluminum body with a chrome-plated 1/4 inch shackle for extra corrosion resistance. The Medeco 521 G8R takes a different approach, a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder. Stainless gives you the harder body and the weather-tight design; the A31 gives you an aluminum body that ships complete and factory keyed with no cylinder to source separately. Pick by whether you already stock the cylinder for the Medeco.
17) How many A31 padlocks come in a case for a bulk facility order?
The A31 ships 6 per shelf pack and 24 per master carton. That matters if you are outfitting a storage facility or a plant and want whole cartons rather than loose counts. Keep in mind each lock is keyed different, so a 24-carton is 24 separate keys.
18) What color is the A31 body, and can it be marked for asset tracking?
Grey is the body color, which is the natural solid aluminum finish. American Lock offers laser engraving and custom marking on this line, so locks can be numbered or stamped with a department, unit, or asset ID before they ship. That is common on self-storage doors and on maintenance lockers where you need to tell identical locks apart on sight.
19) Is the ABUS 76/40 the same kind of lock as the American Lock A31?
They share a 1/4 inch shackle diameter but differ in body construction. The ABUS 76/40 is a plastic-covered aluminum core padlock at 1 37/64 inch width, so the aluminum sits inside a plastic jacket that protects painted or finished surfaces from marring. The A31 is solid aluminum at 1-1/2 inch wide with no covering, which is why it suits manufacturing and harsh outdoor conditions where a plastic jacket would take abuse. Choose the 76/40 when the lock rests against finished equipment, the A31 when it does not.
20) What padlock works better than the American Lock A31 on a boat or dock locker?
The ABUS T84MB/30 Nautic is built for that use, a black sleeve padlock with a 13/64 inch shackle diameter and 1 17/64 inch body width, sold in a three pack. It is a lighter lock than the A31, which runs a 1-1/2 inch solid aluminum body on a 1/4 inch chrome shackle. For marine lockers and small hatches the T84MB/30 sizing and sleeve suit the hardware; for a dock gate or larger hasp the A31's heavier shackle and corrosion-resistant aluminum body is the better fit.
