Master Lock 5KALF-0337 Laminated Padlock Keyed Alike

Product Description

The MASTER LOCK 5KALF-0337 is a laminated steel padlock supplied keyed alike to key number 0337. It is built for securing gates, storage units, tool chests, job-site equipment, and other access points where multiple locks must open with a single key. The body measures 2 inches wide and 2-1/2 inches tall, with a shackle diameter of 3/8 inches. The laminated steel construction layers multiple steel plates together to create a body that resists cutting and prying. This padlock is typically installed by facilities maintenance personnel, tradespeople, and contractors who need a coordinated keying solution across multiple lock points.

This padlock suits residential and light commercial applications where keyed-alike sets are required. Common scenarios include securing multiple storage rooms or equipment enclosures with a single key, tool crib access on job sites, and fleet vehicle lockboxes. Because this unit ships keyed to the 0337 key code, it can be ordered alongside other 5KALF-0337 units to create a matched set without rekeying. It is sold individually.

Compatibility

Designed as an OEM-style replacement and standard fitment for applications requiring a 2 inch laminated steel padlock on common hasps, chains, and gate hardware.

Installation Notes

Installation requires no special tools — thread the shackle through the hasp or chain and press closed until the locking mechanism engages. Before installation on any secured enclosure, verify that the hasp or anchor hardware is rated for the load and tamper resistance required by the application. Keep a duplicate key stored separately from the lock site. Do not force the shackle if the lock cylinder feels stiff — apply a dry lubricant to the keyway and shackle before use in dusty or outdoor environments.
