American Lock AME-A12KAMK 2KEY – Frequently Asked Questions
1) What does keyed alike master keyed mean on the American Lock A12KAMK padlock?
Every A12KAMK in the order opens with the same change key, and a separate master key opens the whole group. That is the setup for a maintenance crew that needs one key for a run of gates, cages or lockers, plus a supervisor master above it. The cylinder is a non-rekeyable 5-pin APTC12, so the keying is set at the factory and cannot be changed in the field. If you want each lock on its own key under a master instead, that is the A12MK.
2) Can the A12KAMK padlock be rekeyed later if a key goes missing?
No. The A12KAMK uses a non-rekeyable cylinder, so if a key walks you replace the lock rather than re-pin it. For a property where turnover is constant and you want to re-pin in house, look at a removable core padlock such as the Sargent 60-858-2 instead, which takes a core you can swap.
3) Do I have to supply a key code when ordering the A12KAMK?
There is a key code field on the order. If you are adding locks to an existing A12KAMK system, put the code from your current keys there so the new locks come factory keyed to match and open on the same key and master. Leave it off only if you are starting a fresh keyed alike group.
4) What padlock has the same 5/16 inch shackle diameter as the American Lock A12KAMK but uses a rekeyable brass body?
The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, matching the A12KAMK shackle diameter of 5/16 inch. The difference is the body and cylinder approach: the A12KAMK uses a solid aluminum body with a non-rekeyable cylinder factory keyed to your requirements, while the Schlage is a brass-bodied lock in the 20 Series. If you are standardizing on a Schlage keyway across an interior site, the KS23D/KS23F carries the same shackle diameter; if you want an aluminum body for corrosive or outdoor exposure, stay with the A12KAMK.
5) If the facility already runs a small-format interchangeable core system, what padlock should be used instead of the American Lock A12KAMK?
Use the Sargent 60-858-2, a removable core padlock with a 2 inch stainless steel shackle. It lets the site pull and swap cores so padlocks stay on the same keying system as the doors. The A12KAMK takes the opposite approach: its 5-pin APTC12 cylinder is non-rekeyable and is factory keyed alike under a master key when the order is placed. Choose the Sargent when key control is managed in-house with cores, and the American Lock when you want a sealed cylinder that cannot be rekeyed in the field.
6) Which padlock should be used for lockout tagout instead of the American Lock A12KAMK?
For lockout tagout, look at the ABUS 72/30 anodized aluminum safety padlock, with a 1-1/4 inch body width and 3/16 inch shackle diameter, or the ABUS 74/40 insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle diameter and 1-1/2 inch body. Those are purpose-built safety locks in lighter bodies. The A12KAMK is a commercial padlock with a 1-3/4 inch solid aluminum body and a 5/16 inch boron alloy shackle, keyed alike under a master key, which is the opposite of the one-key-per-worker convention lockout programs use.
7) Is an aluminum body padlock good enough for outdoor and coastal use?
That is the reason this one exists. The body is solid aluminum, which does not rust, and the boron alloy steel shackle is plated for corrosion resistance. It is a common pick for wash-down areas, marine and chemical environments. If you want a fully sealed marine lock instead, the ABUS T84MB/30 Nautic uses a sleeved body, and Medeco's 521 G8R is a weather-tight solid stainless steel body.
8) How many keys come with each American Lock A12KAMK padlock?
You pick that at order time: 0, 1, 2, 3 or 4 keys per lock, with 2 keys per lock as the standard. Order 0 keys when you already hold the key section for that code and only need bodies. Since these are keyed alike under a master, most fleet buyers take two per lock and keep a small set of spares rather than a key per lock.
9) Can I get the A12KAMK padlock with a chain attached?
Yes. The chain option is either NONE or a #40 sash chain, 9 inches (229mm) long, zinc plated. The chain version keeps the lock captive on the gate, cage door or electrical panel so it does not get set down and lost, which is why utility and self-storage crews spec it.
10) How do American Lock A12, A11 and A10 aluminum padlocks differ?
Same solid aluminum family, different shackle heights. The A12 carries a 3 inch shackle, with the A10 and A11 being the shorter-shackle versions of the same body. Within each, the suffix sets the keying: KD keyed different, KA keyed alike, MK keyed different under a master, KAMK keyed alike under a master. So A12KAMK is the long shackle, one common key, master keyed above it.
11) How does the A12KAMK compare with a brass body padlock like the Schlage KS23?
Both take a 5/16 inch shackle, so they pass through the same hasps, but the bodies differ. The American A12KAMK is solid aluminum, lighter and non-rusting, with a non-rekeyable factory-set cylinder. The Schlage KS23D/KS23F is a brass body padlock, and Medeco's 5260 is a brass body with a heavier 7/16 inch shackle. Choose the aluminum A12KAMK for corrosive or outdoor runs where you want sealed, fixed keying across a fleet.
12) What is a heavier-duty alternative to the American Lock A12KAMK for exposed outdoor gates?
Two options step up in body material. The Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less pop-out cylinder. The Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter in satin chrome, a thicker shackle than the A12KAMK 5/16 inch. The A12KAMK answers exposure with a solid aluminum body and a chrome plated boron shackle rather than with stainless or brass mass, and it ships factory keyed rather than requiring a cylinder to be supplied.
13) What is the difference between the American Lock A12KAMK and the Sargent 758 and 858 padlocks?
The Sargent 758 is a key retaining standard padlock in US4 satin brass, meaning the key cannot be withdrawn while the lock is open. The Sargent 858 is the non-key-retaining version, also US4 satin brass with a stainless steel shackle. The A12KAMK does not divide on that feature; it is a solid aluminum body lock with a 3 inch shackle length and a non-rekeyable cylinder keyed alike under a master key. Pick the 758 where a key left in an open lock would be lost on a loading dock, and the A12KAMK where an aluminum body and a long shackle matter more.
14) Is the ABUS 76/40 a substitute for the American Lock A12KAMK on self-storage units?
They are not equivalent. The ABUS 76/40 is a plastic-covered aluminum core padlock with a 1/4 inch shackle diameter and a body width of 1 37/64 inch, so both the shackle and the body are smaller than the A12KAMK 5/16 inch shackle and 1-3/4 inch body. The plastic cover also protects painted surfaces rather than adding cut resistance. The A12KAMK is the one that runs keyed alike under a master key across a bank of units, which is usually the deciding factor for storage operators.
15) What padlock gives audit trail and scheduled access instead of a mechanical key like the American Lock A12KAMK?
The Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and cylinder included. It shares the A12KAMK 5/16 inch shackle diameter, so hasp fit is comparable, but access is managed electronically rather than by a cut key. The A12KAMK is purely mechanical, with a non-rekeyable 5-pin APTC12 cylinder factory keyed alike under a master key, and ships with 0 to 4 keys per lock depending on how you order it.
16) How are American Lock A12KAMK padlocks packed for a large order?
Six locks to a shelf pack and 24 to a master carton. Handy if you are standardizing a site: order in multiples of 24 and the cartons arrive intact, all on the same keyed alike code and master.
17) Is the A12KAMK padlock suitable for self-storage units and employee lockers?
Yes, that is one of its main uses. Solid aluminum body at 1-3/4 inches wide, a 3 inch boron shackle that clears locker hasps and roll-up door latches, and factory keying so a facility manager holds one master over a building of units. It is a commercial-duty lock, not a residential one.
18) Is the ABUS T84MB/30 a lighter-duty option than the American Lock A12KAMK?
Yes. The ABUS T84MB/30 Nautic is a black sleeve padlock with a 13/64 inch shackle diameter and a 1 17/64 inch body width, sold in a 3-pack, so it is sized for lockers, cabinets and marine gear. The A12KAMK is substantially larger at 1-3/4 inch body width with a 5/16 inch shackle and a 3 inch shackle length, and it supports keyed alike master keying across a property. Use the ABUS where the hasp is small and the exposure is light, and the American Lock where one key set has to cover many locks.
