Master Lock Rekeyed Padlock Boron Alloy KD

This Master Lock padlock uses a boron alloy shackle and a steel body with Advanced Cylinder Technology. It operates with a five-pin cylinder on the Master K6000 keyway and opens with key number 11G302. The shackle dimensions are 5/16 in diameter, 1 3/16 in height, and 29/32 in width. The rectangular body measures 2 5/16 in high, 1 3/4 in wide, and 2 1/2 in thick.

High-security keyed-alike access for managed entry

The unit is rekeyable and requires control key registration, suiting facilities that manage master-key systems. It lacks weather resistance, so outdoor exposure is not recommended. Buyers needing a weatherproof seal or a non-rekeyable disposable lock should consider other options. Buyers who need interchangeable cores or a different keyway profile cannot use this model.

Five-pin Master K6000 cylinder keyed to 11G302

The cylinder uses five pins in the Master K6000 keyway and is factory keyed to 11G302. Control key registration is mandatory for this configuration. This specific keyway and key number combination determines whether the padlock integrates with an existing access system.
