Master Lock 1KA-0548 Laminated Steel Padlock Keyed Alike

Product Description

The MASTER LOCK 1KA-0548 is a laminated steel padlock designed for commercial and industrial security applications. The lock body measures 1-3/4 inches wide and is built from reinforced laminated steel layers for extra strength. The hardened steel shackle stands 15/16 inches tall with a 5/16-inch diameter, providing strong cut resistance. A dual ball bearing locking mechanism delivers maximum pry resistance. The non-rekeyable 4-pin W1 cylinder resists picking and drilling. Licensed locksmiths, facilities maintenance crews, and security professionals specify this padlock for high-demand environments.

This padlock suits industrial facilities, warehouses, job sites, and commercial properties where multiple access points need to be secured with a single key. The keyed alike feature means multiple 1KA-0548 units can be ordered to operate on the same key, streamlining access management across gates, lockers, equipment cabinets, and storage areas. Units can also be ordered to match other locks fitted with the W1 cylinder, allowing integration into an existing keyed alike system.

Designed for keyed alike pairing with other MASTER LOCK No. 1KA series padlocks and locks fitted with the W1 cylinder. Suitable as a direct replacement or addition in any existing W1 keyed alike system.

Installation Notes

Installation requires no tools — the shackle clicks into the lock body and secures with a standard push-and-close motion. Before deploying in a keyed alike configuration, verify all locks in the group share the same key code designation. Inspect shackle clearance on the intended hasp or staple before purchase to confirm fit. A licensed locksmith or security professional should oversee large-scale keyed alike deployments.
