High-Security Padlock for Traffic & Parking

The American Lock A5100 is a rectangular padlock built for traffic and parking lot use. Its boron shackle and steel body provide high-security resistance to cutting and forced entry. Weather-resistant construction ensures reliable outdoor performance. Rekeyable design allows cylinder changes without replacing the entire lock.

Keyed-Different System Limits Master-Key Convenience

Each padlock operates on a unique key code with no factory master-key capability. Control key registration is not required, but the keyed-different setup prevents a single key from opening multiple units. This suits sites where individual access control outweighs key-management simplicity. The American AK5 keyway restricts duplication to authorised channels.

5-Pin Cylinder Determines Pick Resistance

The lock uses a 5-pin tumbler mechanism that defines its baseline security against picking and bumping. No interchangeable core is fitted, so the cylinder stays integral to the body. Buyers needing higher pin counts or interchangeable-core flexibility should specify a different model.

Questions about this item

How do I decide between the standard shackle and another shackle option for the A5100?

The A5100 is supplied with a standard shackle only; the shackle diameter is 1/4 in, height 1 in and width 3/4 in, so choose this version when those dimensions fit your hasp or chain.

What does the 5-pin cylinder mean for day-to-day security on the A5100?

Five pins provide a larger combination range than four-pin cylinders, increasing resistance to picking while still allowing rekeying if keys are lost.

How does the American AK5 keyway affect key control and duplication?

The AK5 keyway is specific to American Lock, so blanks are less common at general hardware stores, giving tighter control over who can cut copies.
