American Lock AME-A1366MK BLU 2KEY – Frequently Asked Questions

1) What does the MK suffix mean on the American Lock A1366MK padlock?
MK means the locks ship keyed different but under a master key system, so each padlock has its own change key and one master key opens the whole group. If you want every lock on the same change key instead, that is the A1366KA; keyed alike under a master is A1366KAMK, and A1366KD is keyed different with no master. Uncombinated (A1366UN) and zero-bitted (A1366KZ) ship for a locksmith to pin.
2) Will the A1366 padlock fit through my hasp? What are the shackle dimensions?
The shackle is 3/8 inch diameter with a 2 inch clearance height and 3/4 inch between the legs. So the hasp staple opening has to take a 3/8 inch rod, and the two points you are locking through cannot be more than 3/4 inch apart. Body is 2 inches wide.
3) Can these padlocks be rekeyed later, or do I have to replace them?
They are rekeyable. The A1366MK uses a 6-pin APTC14 cylinder that is pick resistant and rekeyable, with tens of thousands of key changes available, so a locksmith can re-pin them into a new or expanded master system instead of scrapping the locks when tenants or staff turn over.
4) What is the closest alternative to the American Lock A1366MK if I need a 2 inch shackle on a padlock?
The American Lock A1366MK pairs a 2 inch wide solid aluminum body with a 2 inch shackle length at 3/8 inch shackle diameter. The nearest match by shackle length is the Sargent 60-858-2, a removable core padlock with a 2 inch stainless steel shackle. The Sargent is a removable core design, so the cylinder swaps out as a unit, while the A1366MK uses a rekeyable 6-pin APTC14 cylinder that is repinned in place.
5) I need a padlock with a thicker shackle than the American Lock A1366MK. What should I look at?
The A1366MK shackle is 3/8 inch in diameter. For a heavier shackle, the Medeco 5260 brass body padlock uses a 7/16 inch shackle diameter with M3 key technology in a satin chrome finish. Note the body material changes as well: the A1366MK body is aluminum, while the Medeco 5260 is brass.
6) Which padlocks look like a substitute for the A1366MK but are not?
Two to rule out. The Medeco 54515G XT is an electronic indoor/outdoor padlock with a 5/16 inch shackle, so it runs on an electronic credential system rather than the mechanical 6-pin APTC14 cylinder the A1366MK uses. The ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, 1/4 inch shackle and 1-1/2 inch body, built for lockout/tagout rather than as a general-purpose solid body lock. Neither will key into an American Lock master system.
7) Can I mix the American Lock A1366MK with Sargent or Schlage padlocks on the same master key?
No. The A1366MK is master keyed on American Lock's rekeyable 6-pin APTC14 cylinder. The Sargent 60-858-2 is a removable core design in the 758/858 series, the Sargent 82-856 is KESO series, the Medeco 5260 runs M3 key technology, and the Schlage KS23D/KS23F is a 20 Series brass lock. Each of those keys into its own manufacturer system, so a mixed fleet needs one platform chosen up front.
8) What is the difference between the American Lock A1365, A1366 and A1367 aluminum padlocks?
They are the same 2 inch wide solid aluminum body and differ by shackle height. The A1366 carries the 2 inch shackle. A1365 and A1367 are the shorter and taller shackle options in the same family, so pick by how much clearance your hasp or chain needs, not by lock strength.
9) Can I color code padlocks by department or trade with these?
Yes. The A1366MK aluminum body comes in blue, brown, red and yellow anodized finishes, which is how most facilities split locks by crew, building or contractor while still keeping them all on one master key. Any color can be ordered with or without a chain.
10) How many keys come with each American Lock A1366MK padlock?
Standard is 2 keys per lock. You can also order 1, 3 or 4 keys per lock, or 0 keys per lock if the site already has keys cut on the system and you only want the padlock bodies.
11) Does the A1366MK padlock come with a chain to keep it attached to the gate?
A chain is an option, not standard. You can add a #40 sash chain, 9 inches long, zinc plated, so the padlock stays tethered to the gate, locker or valve cover when it is off the hasp. The other choice is NONE, which is the bare padlock.
12) Is an aluminum body padlock strong enough for outdoor gates and yards?
The body is solid aluminum with a black anodized finish for weather exposure, and the cut resistance comes from the boron alloy steel shackle rather than the body. A dual ball bearing locking mechanism resists pulling and prying. It is a commercial-rated lock used on self storage, lockers, outdoor gear and manufacturing equipment. If you need a metal body rather than aluminum, a stainless steel option is the Medeco 521 G8R weather-tight padlock, and brass bodies include the Sargent 758 and the Schlage KS23D.
13) I need a smaller padlock for lockout tagout, is this the right one?
The A1366 is a 2 inch wide body, heavier than a typical LOTO lock and aimed at gates, storage units and equipment security. For compact safety lockout use, ABUS aluminum safety padlocks are the smaller option: the 72/30 is a 1-1/4 inch body with a 3/16 inch shackle, and the 74/40 is a 1-1/2 inch insulated body with a 1/4 inch shackle and a 6-pin cylinder.
14) For a wet or coastal outdoor location, is the A1366MK the right choice or is there a better option?
The A1366MK uses a solid aluminum body with a black anodized finish rated by American Lock for harsh outdoor conditions. If you want a stainless or sealed body instead, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder, and the ABUS T84MB/30 Nautic uses a black sleeve over the body with a 13/64 inch shackle and 1-17/64 inch body width.
15) The A1366MK does not retain the key when unlocked. What padlock does that instead?
If you need the key captive while the lock is open so it cannot be walked off, the Sargent 758 is a key retaining standard padlock in a US4 satin brass finish. Its counterpart, the Sargent 858, is non-key retaining with a stainless steel shackle in the same US4 satin brass. The A1366MK is a rekeyable solid aluminum body lock 2 inches wide.
16) We standardize on brass bodied padlocks. What are the brass equivalents to the A1366MK?
The A1366MK body is solid aluminum. For brass, the Sargent 82-856 is a non-key retaining padlock with a 2 inch by 2 inch brass case and stainless steel shackle, the Medeco 5260 is a 52 Series brass body lock with a 7/16 inch shackle, and the Schlage KS23D/KS23F is a brass padlock with a 5/16 inch shackle diameter. The Sargent 82-856 case footprint matches the A1366MK 2 inch body width.
17) How are American Lock A1366MK padlocks packed for a bulk order?
They come 6 to a shelf pack and 24 to a master carton, which is what to size a standardization buy against if you are rolling locks out across a property or facility.
