Job Site Padlocks & Security Locks — Master Lock Keyed-Alike & Heavy Duty

One Key. Every Lock. Total Site Control.

Nothing slows a job site down like a crew member locked out of a tool box, Conex, or gate because someone has the wrong key. Keyed-alike padlocks solve that problem instantly — one key opens every lock on the site. Master Lock's Magnum series is the most trusted name in job site security, with all-weather covers, hardened steel shackles, and the kind of pick resistance that keeps your tools where you left them.
