LockPickingLawyer tests American Lock A2500 padlock's real-world security

LockPickingLawyer’s latest American Lock episode went after a lock that looks like it belongs on industrial hardware, not a hobby workbench. The June 6 video, titled American Lock’s Best Padlock? (Model A2500), put the A2500 in front of the same consumer-education scrutiny that has made the channel a reference point for picking, bypass and defeat testing.

American Lock pitches the A2500 as a 2-7/8-inch shackleless, solid-steel, flat-back padlock in hockey-puck form, built for high-security gates, trucks, heavy-security hasps, freight-line and automotive security. The product literature says it uses a removable 6-pin solid-brass re-keyable cylinder and is resistant to all weather, which is exactly the kind of spec sheet that gets attention from both locksport people and buyers trying to separate real protection from marketing gloss.

The company’s own catalog leans hard into the security claims. It says American Lock’s round, hidden-shackle padlocks are designed to resist drilling, sawing, prying, crowbars, dent pullers and hammers, and that six-pin tumbler cylinders provide superior pick resistance. The same catalog groups the A2500 with the A2010 and A2001 as flat-back models meant to attach to A801 or A802 high-security hasps, a reminder that the lock is part of a broader industrial system rather than a standalone novelty. A reseller listing put the A2500 at $299.96, called out the lack of an outside shackle to cut or saw, and described it as a solid one-piece steel case with two keys included.

That price puts the A2500 squarely in premium territory, which is why the real-world test matters. A heavy case, a hidden shackle and a respected brand name do not automatically settle the question of pick resistance, drill resistance or whether the design actually closes off the attacks people in the community care about most. For everyday users, the lock only makes sense if the application really needs a puck-style body and the rest of the hardware, including the hasp, is up to the same standard. For hobbyists, it is another American Lock platform to study alongside earlier series 700, 1100 and 5100/5200-family reviews.

That is the useful lens here: the A2500 may look like a serious answer to cutting and prying, but the value of a $299.96 padlock lives or dies on the parts you cannot see.
