Master Lock 1KALJ-3753 Keyed Alike Padlock

Product Description

The MASTER LOCK 1KALJ-3753 is a keyed alike padlock designed for use by trades professionals who need consistent key access across multiple lock points. Keyed alike configurations allow a single key to operate several padlocks on the same job site or facility, reducing the number of keys a technician or contractor must carry. This padlock suits applications in HVAC, electrical, plumbing, and general contractor environments where lockout/tagout compliance and secure equipment access are daily requirements. Weighing 0.65 pounds, it is built for durable field use.

The 1KALJ-3753 is suited for residential and light commercial applications where multiple padlocks must operate from one key. Typical installation scenarios include securing electrical panel enclosures, HVAC equipment access panels, gate hasps, and storage units. It is particularly useful for service companies managing multiple technicians who share common key sets across a fleet of padlocks at a single customer site or across recurring service locations.
