American Lock AME-A3105CYUN BLK 2KEY – Frequently Asked Questions

1) What does "uncombinated" mean on the American Lock A3105CYUN padlock, and does it come with keys?
Uncombinated means the A3105CYUN ships with a standard SFIC core that has not been pinned to any key combination. A locksmith or facility keying department pins it into your existing system. Because the combination isn't set at the factory, the key count is an option you pick when ordering, from 0 keys per lock through 1, 3, 4, or the standard 2 keys per lock. If you don't run your own keying, order one of the pre-combinated versions instead: A3105CYKD keyed different, A3105CYKA keyed alike, A3105CYMK master keyed, or A3105CYKAMK keyed alike and master keyed.
2) Will an American Lock A3105CYUN padlock take the same SFIC core as the rest of my building's key system?
The A3105CYUN is built around a standard small format interchangeable core, the same 6 or 7 pin figure-eight core format used on SFIC cylindrical locks, mortise housings and cabinet locks. It accepts a standard SFIC keyway, and 16 interchangeable core keyways are available, so it can be matched into an existing SFIC master key system rather than carrying a key of its own. One control key pulls the core the same way it does on your door hardware.
3) Does the A3105CYUN aluminum padlock include the SFIC core, or do I have to buy the core separately?
The CY in A3105CYUN means the padlock comes with the standard SFIC cylinder installed, just uncombinated. If you already have cores on the shelf and want the padlock body alone, order the WO version instead: A3105WOUN is the same aluminum padlock without a cylinder, uncombinated. The WO line also runs in longer shackles as A3106WO and A3107WO.
4) Will a 1/4 inch shackle American Lock A3105 padlock fit through my hasp or locker staple?
Check three numbers against the opening. The shackle is 1/4 inch in diameter, the clearance between the shackle legs is 3/4 inch, and the vertical shackle clearance is 1 inch. The lock body is 1-1/2 inches wide. So the hasp staple has to pass a 1/4 inch shackle and sit within a 3/4 inch span, and you need 1 inch of height to get around it. A thicker chain link or a heavy commercial hasp staple often won't clear a 1/4 inch shackle, and a wide two-hole hasp can exceed the 3/4 inch inside width.
5) What is the closest aluminum-body padlock to the American Lock A3105CYUN if the small format interchangeable core is not needed?
The A3105CYUN is a solid aluminum padlock with a 1-1/2 inch body width and a 1/4 inch shackle diameter, built around a standard SFIC keyway so the core can be swapped into an existing keying system. Where the opening does not need an interchangeable core, the ABUS 76/40 is a plastic-covered aluminum core padlock with the same 1/4 inch shackle diameter and a 1-37/64 inch body width, and the ABUS 72/30 is an anodized aluminum safety padlock with a narrower 1-1/4 inch body and a 3/16 inch shackle. The ABUS bodies are a fixed cylinder rather than a removable core, so keying is done at the lock instead of by pulling a core.
6) Is a brass-body padlock like the Schlage KS23D or Medeco 5260 a substitute for the American Lock A3105CYUN?
Not directly. The A3105CYUN body is solid aluminum, which keeps it light and spark resistant for utility and tool crib work, and its shackle is 1/4 inch in diameter. The Schlage KS23D/KS23F is a brass padlock with a 5/16 inch diameter shackle, and the Medeco 5260 is a 52 Series brass body padlock with a 7/16 inch shackle diameter and M3 key technology in satin chrome. The heavier shackle diameters on the brass locks will not pass through a hasp or chain link drilled for a 1/4 inch shackle, so the hasp opening has to be checked before swapping.
7) Which high security padlock should be specified where the American Lock A3105CYUN's standard SFIC keyway is not restrictive enough?
The A3105CYUN takes a standard SFIC keyway, which is an open format many manufacturers cut for. Where key control has to be tighter, the Sargent 82-856 is a KESO Series non-key retaining padlock with a 2 inch by 2 inch brass case and a stainless steel shackle, and the Medeco 5260 is a 52 Series brass body padlock using M3 key technology with a 7/16 inch shackle diameter in satin chrome. Both are patented-key platforms rather than a swappable small format core, so they run on their own key system instead of the one already in the building's SFIC doors.
8) I need to color code padlocks by crew or department. What colors does the American Lock A3105 aluminum padlock come in?
Nine body colors: black, blue, brown, clear, green, orange, purple, red and yellow. That is anodized color over the solid aluminum body, so it is part of the finish rather than a sticker that comes off in a tool crib. Departments and utility crews use it to sort locks by trade, shift or building without keying differences.
9) Can I get an American Lock A3105 padlock with a chain so it stays attached to the locker or gate?
Yes. The A3105 aluminum SFIC padlock is orderable with a #40 sash chain, 9 inches (229mm) long, zinc plated, or with no chain at all. The chain keeps the lock captive on a locker door, valve handle or gate frame so it doesn't walk off or get set down and lost once it's opened. Specify the chain option on the order; it is not added afterward.
10) Is an aluminum padlock strong enough for outdoor gates and utility work, or should I use steel or brass?
The tradeoff is corrosion and weight versus mass. The A3105 body is solid aluminum, corrosion resistant and spark resistant, which is why it turns up in utility work, tool cribs and self storage. Cut resistance comes from the shackle, not the body: it's hardened boron alloy steel at 1/4 inch diameter. If you want a heavier metal body instead, ZenSupply carries the Sargent 858 with a stainless steel shackle and US4 satin brass finish, the Medeco 5260 brass body padlock with a 7/16 inch shackle, and the Medeco 521 G8R with a solid stainless steel body. A 7/16 inch shackle resists a bolt cutter far better than 1/4 inch, but it will not pass a small locker staple.
11) What other removable core padlocks work with an existing key system if the American Lock A3105 doesn't fit?
Sargent makes a removable core padlock in the 758/858 family, the 60-858-2, with a 2 inch stainless steel shackle. That 2 inch shackle clears a taller hasp or a chain link that the A3105's 1 inch shackle clearance will not reach. Staying within American Lock, the same aluminum body is offered with longer shackles as the A3106 and A3107. Note the Sargent takes Sargent removable cores, not a standard SFIC core, so it keys into a different system than the A3105's standard SFIC keyway.
12) For lockout tagout use, how does the American Lock A3105CYUN compare to an ABUS safety padlock?
The A3105CYUN comes in nine lockbody colors including red, yellow, blue, green, orange, purple, brown, black and clear, and can be ordered with zero keys per lock, which is how a lockout program keeps a lock from being opened by a second key. Its 1-1/2 inch aluminum body carries a standard SFIC core. The ABUS 74/40 is an insulated safety padlock with a 6-pin cylinder, a 1/4 inch shackle diameter and the same 1-1/2 inch body width, and the ABUS 72/30 is an anodized aluminum safety padlock at 1-1/4 inch body width with a 3/16 inch shackle. The ABUS locks use a fixed 6-pin or standard cylinder rather than a core that pulls for rekeying.
13) What is the difference between the American Lock A3105CYUN and a Sargent 758 or 858 padlock?
The A3105CYUN is an aluminum-body lock built for a standard SFIC core and shipped uncombinated, meaning the core is pinned to the facility's own key system before it goes into service. 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. Key retention decides whether the key can be withdrawn while the lock is open, which matters on lockers and tool cribs where a key left in an open lock walks off.
14) What should be used instead of the American Lock A3105CYUN on a marine or salt-air opening?
The A3105CYUN uses a corrosion resistant solid aluminum body with a black anodized finish and a hardened boron shackle, and it is ordered uncombinated so the SFIC core is pinned locally. Where the exposure is heavier, the Medeco 521 G8R is a weather-tight padlock with a solid stainless steel body, supplied less the pop-out cylinder. 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, a smaller lock for lighter marine duty rather than an equivalent to the 1-1/2 inch aluminum body.
15) Which padlock replaces the American Lock A3105CYUN when access needs to be audited electronically?
The A3105CYUN is a mechanical lock keyed through a standard SFIC core, so access control is handled by which keys are cut and issued. Where the facility wants the lock itself to carry the credential, the Medeco 54515G is an XT electronic indoor/outdoor padlock, non-key retaining, with a 5/16 inch shackle diameter and supplied with cylinder. That is a different program to administer, not a drop-in for an SFIC keyway, and its 5/16 inch shackle is larger than the 1/4 inch shackle on the American Lock.
16) The American Lock A3105CYUN shackle is only 1 inch tall. What padlock has more clearance for a thick hasp or a chain?
The A3105CYUN has a 1 inch shackle length with a 3/4 inch shackle width, which is sized for a locker hasp or a standard tool crib latch, and it can be ordered with a #40 sash chain 9 inches long in zinc plated finish for tethering the lock to the fixture. Where the shackle itself has to reach further, the Sargent 60-858-2 is a removable core padlock with a 2 inch stainless steel shackle, which keeps the interchangeable core approach while clearing a thicker hasp.
17) How many American Lock A3105CYUN padlocks come in a case if I'm buying for a whole property?
Six per shelf pack and 24 per master carton. For a self storage facility or a locker bank, that's the unit to think in: a master carton covers 24 openings. Since these ship uncombinated, plan the pinning labor alongside the count.
18) Will an aluminum body padlock hold up in a wash-down, coastal or chemical environment?
Corrosion resistance is the main reason to pick this one. The solid aluminum body resists corrosion where a plated steel padlock would rust, and it's spark resistant, which matters around fuel and gas work. The finish is black anodized rather than a coating that chips. Salt spray and chemical exposure will eventually dull anodizing, so for the harshest marine service ZenSupply also carries the ABUS T84MB/30 Nautic with a black sleeve and the Medeco 521 G8R weather-tight padlock with a solid stainless steel body.
19) What stops someone prying an American Lock A3105 padlock open at the shackle?
A dual ball bearing locking mechanism holds the shackle at both legs, so pulling or prying on the shackle loads two bearings instead of a single spring latch. Combined with the 1/4 inch boron alloy steel shackle, the attack shifts to cutting rather than twisting. The short 1 inch shackle clearance helps too, since it leaves little room to get a tool between the shackle and the hasp.
