American Lock AME-A1205MK BLK 2KEY – Frequently Asked Questions

1) What does the MK in American Lock A1205MK mean, and how is it different from A1205KA or A1205KD?
MK means keyed different under a master key. Each A1205MK padlock opens on its own individual key, and all of them also open on a common master key you specify. A1205KA is keyed alike (every lock on the same change key), A1205KD is keyed different with no master, and A1205UN comes uncombinated. If you want one key for a supervisor plus unique keys for each user, MK is the one to order. A1205KAMK gives you keyed alike under a master instead.
2) Do I have to give a key code when ordering the A1205MK master keyed padlock?
Yes. Because the A1205MK is cut to an existing master key system, there is a Key Code field on the order that has to be filled in. Give the master key code and change key information you want these cut to, so the locks arrive keyed into your existing American Lock system rather than to random bittings.
3) How big is the shackle opening on the American Lock A1205 aluminum padlock? Will it fit my hasp?
The shackle is 5/16 inch in diameter with a 1-1/8 inch vertical clearance and 3/4 inch between the legs. The body itself is 1-3/4 inch wide. So your hasp staple has to accept a 5/16 inch shackle, and whatever you are locking through needs to fit inside that 1-1/8 by 3/4 inch opening. For thicker chain or a bigger hasp loop, step up to the A1206 (longer shackle) or A1207.
4) What is the closest alternative to the American Lock A1205MK if I need a padlock with the same 5/16 inch shackle diameter?
The A1205MK carries a 5/16 inch diameter shackle on a 1-3/4 inch wide solid aluminum body. Two comparable locks share that shackle diameter: the Schlage KS23D/KS23F, which uses a brass body, and the Medeco 54515G XT electronic indoor/outdoor padlock, which is non-key-retaining and supplied with a cylinder. The Schlage is the closer mechanical match; the Medeco 54515G adds electronic credential control rather than a purely mechanical key system.
5) For lockout/tagout, what should I look at besides the American Lock A1205MK aluminum padlock?
The A1205MK is a 1-3/4 inch wide anodized aluminum body offered in black, blue, brown, clear, green, orange, purple, red and yellow for color-coded identification, with a 5/16 inch boron shackle. If you want a smaller, lighter body for the same color-coded safety role, the ABUS 72/30 is an anodized aluminum safety padlock with a 1-1/4 inch body and 3/16 inch shackle. Where the lock may contact live parts, the ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, 1-1/2 inch body and 1/4 inch shackle.
6) I need a padlock for a facility on a small-format interchangeable core system - is the A1205MK the right pick?
The A1205MK uses a rekeyable 5-pin APTC12 cylinder and is supplied keyed different under a master key. If your facility standardizes on removable cores instead, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, which lets the core be swapped rather than the cylinder repinned.
7) Can I color code padlocks by department or by crew with the A1205MK?
That is exactly what the anodized aluminum body is for. The A1205MK comes in black, blue, brown, clear, green, orange, purple, red and yellow, so you can assign a color per trade, per shift, or per area and still run them all under one master key. Suffixes follow the color (A1205MKBLU, A1205MKRED, A1205MKYLW and so on).
8) Is the American Lock A1205 rekeyable, or do I have to replace the lock when someone loses a key?
Rekeyable. It uses a 5-pin APTC12 cylinder that a locksmith can repin, with tens of thousands of key changes available. Lose a key or turn over an employee and you repin the cylinder into the same system instead of buying new padlocks.
9) Will an aluminum padlock hold up outdoors or in a wash-down plant?
The A1205 body is solid aluminum, which does not rust, and the black anodized finish is meant for harsh outdoor and manufacturing environments. The shackle is hardened boron alloy steel for cut resistance, and a dual ball bearing locking mechanism resists pulling and prying. Common uses are self-storage units and lockers, tool cribs, and safety lockout. If you need a stainless body instead, the Medeco 521 G8R is a solid stainless steel weather-tight padlock.
10) How many keys come with each A1205MK padlock, and can I order fewer?
Standard is 2 keys per lock. You can also specify 0, 1, 3 or 4 keys per lock. Facilities running a master key system often order 0 or 1 key per lock and issue keys separately from their own key cabinet.
11) What else could I use instead of an aluminum safety padlock like the A1205?
A few directions depending on the job. For a lighter lockout tag lock, the ABUS 72/30 anodized aluminum safety padlock runs a 1-1/4 inch body and 3/16 inch shackle. The ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, 1-1/2 inch body and 1/4 inch shackle. For high-security keying instead of color-coded lockout, the Medeco 5260 is a brass body padlock with a 7/16 inch shackle and M3 key technology, and the Schlage KS23D/KS23F is a brass padlock on a 5/16 inch shackle like the A1205. If you run small format interchangeable cores across a facility, the Sargent 60-858-2 removable core padlock with a 2 inch stainless shackle is the one to look at.
12) Which padlock holds up better than the A1205MK in wash-down or marine exposure?
The A1205MK uses a solid aluminum body with an anodized finish, which suits harsh outdoor conditions and manufacturing environments. For direct salt or constant wet exposure, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less 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. The Medeco 521 G8R is the heavier-bodied option; the T84MB/30 is a small marine-style lock.
13) Is a plastic-covered padlock like the ABUS 76/40 a substitute for the A1205MK aluminum body?
They are not the same construction. The A1205MK is a solid aluminum body 1-3/4 inches wide with a 5/16 inch boron alloy steel shackle. The ABUS 76/40 is a plastic-covered aluminum core padlock measuring 1-37/64 inches wide with a 1/4 inch shackle diameter. The plastic cover protects finished surfaces from marring; the A1205MK relies on the anodized aluminum body itself and carries the larger shackle.
14) Which padlock should I specify instead of the A1205MK for a high-security key control program?
The A1205MK uses a 5-pin APTC12 rekeyable cylinder with Edge key control and pick resistance. If the specification calls for a patented high-security key system, the Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter using M3 key technology in satin chrome, and 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 system. Both use larger brass bodies rather than the A1205MK aluminum body.
15) I need a longer shackle than the A1205MK offers to pass through a thick hasp - what else works?
The A1205MK shackle is 1-1/8 inches tall with a 3/4 inch clearance width, which suits standard hasps and lockout points. For a taller shackle clearance, the Sargent 60-858-2 removable core padlock and the Sargent 82-856 both use a 2 inch stainless steel shackle. If the reach is the only issue and you want to keep the American Lock body, the A1205MK is also available with a 9 inch long #40 zinc plated sash chain.
16) Can the Medeco 54515G XT replace the American Lock A1205MK on gates I want to audit?
They solve different problems. The A1205MK is a mechanical padlock with a rekeyable 5-pin cylinder, supplied keyed different under a master key so a facility key opens the group. The Medeco 54515G XT is an electronic indoor/outdoor padlock, non-key-retaining, with a 5/16 inch shackle diameter and a cylinder included; it is the choice when you need programmable access rather than a mechanical master key hierarchy. Both share the 5/16 inch shackle diameter.
17) Can I get the A1205 padlock with a chain so it stays attached to the gate?
Yes. The A1205 can be ordered with a #40 sash chain, 9 inches long, zinc plated, or with no chain at all. The chain keeps the lock tethered so it does not walk off a gate or locker.
18) How do American Lock A1205 padlocks ship for a large facility order?
They come 6 to a shelf pack and 24 to a master carton, which is convenient when you are standardizing a building or a plant and issuing locks by department. Mixing colors across a master keyed order is normal for this kind of rollout.
19) Is the A1205MK a commercial grade padlock or a consumer one?
It is a commercial product, sold into self-storage, lockers, tool cribs, manufacturing plants and outdoor gates, and it supports Edge key control, custom keying, and laser engraving or custom marking for asset tagging.
