American Lock AME-A31KAMK 2KEY – Frequently Asked Questions
1) What does "keyed alike, master keyed" mean on the American Lock A31KAMK, and do I have to give a key code when I order?
Keyed alike means every A31KAMK on the order opens with the same change key, and master keyed means they also operate under a master key that can be set to run other locks in the same system. Because the keying is set at the factory, a key code entry is required with the order so the locks are cut to your existing system rather than a random combination. If you need each lock on its own key instead, the A31KD (keyed different) or A31MK (keyed different, master keyed) versions of the same aluminum body lock cover that.
2) Will a 1/4 inch shackle padlock fit through my hasp or locker staple?
The A31KAMK uses a 1/4 inch diameter shackle, so the hasp eye or staple has to accept at least that. Working room is 1-1/2 inch of shackle clearance height with 3/4 inch between the legs, which is the dimension that decides whether it goes around a thicker hasp loop or a chain link. The body itself is 1-1/2 inch wide, so it sits close on tight hardware.
3) Can the A31KAMK be rekeyed later by my locksmith?
No. The 5-pin APTC12 cylinder in the A31KAMK is non-rekeyable, so the keying is fixed at the factory and a locksmith cannot repin it in the field. Plan on ordering replacements to the same key code rather than rekeying. If you need field-serviceable keying, look at a removable core padlock such as the Sargent 60-858-2.
4) What is the closest aluminum-body alternative to the American Lock A31KAMK padlock?
The ABUS 74/40 insulated safety padlock is the nearest match on the two dimensions that matter for fit: it carries a 1/4 inch shackle diameter and a 1-1/2 inch body width, the same shackle diameter and body width as the A31KAMK. The difference is the cylinder and the body treatment - the 74/40 uses a 6-pin cylinder in an insulated body, while the A31KAMK uses a non-rekeyable 5-pin APTC12 cylinder in a solid aluminum body with a chrome shackle. If you need the same hasp clearance but want a rekeyable 6-pin cylinder, the 74/40 is the swap. The ABUS 76/40 also lists a 1/4 inch shackle diameter, on a plastic-covered aluminum core body 1 37/64 inch wide.
5) I need a padlock I can rekey in-house or put on a master key system with removable cores - what should I use instead of the A31KAMK?
The A31KAMK uses a non-rekeyable 5-pin APTC12 cylinder that is keyed at the factory, so once it ships the keying is fixed. For a lock your locksmith can service on site, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle - the core pulls with a control key and swaps into your existing system. The Sargent 82-856 is a non-key-retaining padlock with a 2 inch by 2 inch brass case and stainless steel shackle on the KESO platform. Both are larger-bodied than the 1-1/2 inch wide A31KAMK, so check your hasp opening before you switch.
6) Is an aluminum body padlock a good choice for outdoor or washdown areas?
That is what the A31 aluminum body is for. The solid aluminum body resists the elements and the shackle is chrome plated for corrosion resistance, which is why American Lock points this model at harsh outdoor conditions, manufacturing plants, and self-storage and locker applications. If you want a fully stainless body instead, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body.
7) How many keys come with each American Lock A31 padlock, and can I order them without keys?
Key count is something you pick. The standard is 2 keys per lock, and you can also order 1, 3, or 4 keys per lock, or 0 keys per lock when you are adding to an existing keyed alike system and already hold the keys. Ordering zero keys is common for property managers expanding a locker or storage bank.
8) Can I get this padlock with a chain so it stays attached to the gate or locker?
Yes. The A31KAMK can be ordered with a #40 sash chain, 9 inches (229mm) long, zinc plated, factory attached, or with no chain at all. The chain keeps the lock tethered to the hasp or door so it does not walk off between uses, which is the usual reason storage and utility accounts specify it.
9) What is the difference between the American Lock A30, A31 and A32 aluminum padlocks?
They are the same solid aluminum non-rekeyable family, split by shackle clearance. The A31 is the mid option with a 1-1/2 inch shackle height and a 1/4 inch shackle diameter on a 1-1/2 inch wide body; the A30 is the shorter shackle and the A32 the longer. Each of the three is offered keyed different, keyed alike, master keyed, and keyed alike master keyed, so pick the shackle first and the keying second.
10) What else could I use instead of an aluminum body padlock for lockout or safety tagging?
If the job is lockout/tagout rather than general security, ABUS safety padlocks are the closer fit: the 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle, and the 74/40 is an insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body. The American Lock A31KAMK is built for keyed alike site security, not for personal lockout, since its keying is common across the set by design.
11) For a coastal or washdown site, is the A31KAMK the right padlock or is there something more weather-rated?
The A31KAMK is built for corrosive environments - solid aluminum body with a chrome shackle for extra corrosion resistance - and it is the light-duty choice at 1-1/2 inch wide with a 1/4 inch shackle. If you want a heavier sealed body for the same exposure, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body and a pop-out cylinder design. The ABUS T84MB/30 Nautic is the marine-oriented option, with a black sleeve over a 1 17/64 inch body and a 13/64 inch shackle - a smaller shackle than the A31KAMK, so confirm it passes your hasp.
12) Is the ABUS 72/30 a drop-in replacement for the American Lock A31KAMK?
No - the two are close in family but not interchangeable in a hasp. The ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body width and a 3/16 inch shackle diameter, while the A31KAMK runs a 1-1/2 inch body width and a 1/4 inch shackle diameter. The narrower 3/16 inch shackle will pass through a hasp sized for the A31KAMK but will not fill it, and the 72/30 is a lockout/tagout style safety lock rather than a factory-keyed master-keyed unit like the A31KAMK. Use the 72/30 where you want a lighter anodized body and the smaller shackle is acceptable.
13) What is the brass-body equivalent if I am standardizing a facility on brass padlocks instead of the aluminum A31KAMK?
The A31KAMK body is aluminum. For a brass case on a comparable padlock, the Sargent 758 is a key-retaining standard padlock in a US4 satin brass finish, and the Sargent 858 is the non-key-retaining version with a stainless steel shackle in the same US4 satin brass. On the Medeco side, the 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter in satin chrome, and the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch shackle diameter. All four carry thicker shackles than the A31KAMK's 1/4 inch, so verify hasp clearance on the doors you are converting.
14) We want audit trail and scheduled access on outdoor gates - does the A31KAMK support that?
The A31KAMK is a mechanical padlock with a factory-keyed non-rekeyable 5-pin APTC12 cylinder, so access is controlled by who holds the key and by the master key hierarchy you order. For electronic credentialing on an outdoor opening, the Medeco 54515G is an XT electronic indoor/outdoor padlock, non-key-retaining, with a 5/16 inch shackle diameter and cylinder included. Facilities often run both: the A31KAMK on routine gates and lockers, the electronic unit on the openings that need a record of who opened what.
15) Our hasps need a taller or longer shackle than the A31KAMK - what steps up?
The A31KAMK carries a 1-1/2 inch shackle length with a 3/4 inch shackle width, which suits tight hasps, lockers and self-storage units. Where the hasp or chain loop needs more reach, the Sargent 858 pairs a stainless steel shackle with a brass body, the Sargent 60-858-2 lists a 2 inch stainless steel shackle, and the Sargent 82-856 uses a stainless steel shackle on a 2 inch by 2 inch brass case. If the goal is simply keeping the lock tethered to the gate rather than clearing a taller staple, the A31KAMK is also configurable with a #40 sash chain, 9 inch long, zinc plated.
16) Does key retention differ between the A31KAMK and the Sargent padlocks?
Key retention decides whether the key can be pulled while the lock is open. The Sargent 758 is specified as key retaining, so the key stays captive until the shackle is closed - useful for lockout and for crews who lose keys. The Sargent 858 and the Sargent 82-856 are non-key-retaining, and the Medeco 54515G is likewise non-key-retaining. The A31KAMK is ordered around keying rather than retention: it is a keyed alike master keyed lock, and you can specify the key code plus how many keys ship with each lock, from 0 up to 4 keys per lock.
17) How do these ship if I am buying padlocks for a whole facility?
The A31 aluminum padlocks pack 6 to a shelf pack and 24 to a master carton, which is the count to work from when you are standardizing a locker room or a run of gates on one key. All of them keyed alike means a single change key opens the lot.
18) What color is the A31KAMK padlock body?
Grey. The solid aluminum body carries a grey finish with a chrome plated shackle, so a bank of them reads uniform across a locker room or gate line. American Lock also offers laser engraving and custom marking on this family if you need department or unit numbers on the face.
