Padlock for shared access

The Master Lock 6830KA-10G121 is a rectangular brass padlock supplied keyed alike so that every unit opens with the same 10G121 key. It suits teams, families or site managers who need multiple locks operated by a single key without carrying a bulky bunch.

Hardened shackle and weather resistance

A boron-alloy shackle resists cutting and sawing while the brass body withstands rain and humidity. The five-pin Master K6000 keyway provides high-security pick resistance, and the mechanism operates reliably in outdoor conditions without electronic components that could fail.

Rekeyable design with standard shackle

The lock can be rekeyed by a locksmith if key control changes, extending its service life beyond a lost key. Its standard shackle dimensions fit common hasps, chains and gate latches, and the rectangular brass body offers a firm grip when locking or unlocking in daily use.

Questions about this item

How do I install the Master Lock 6830KA-10G121 and what step is often missed?

Insert the 1/4 in boron alloy shackle through the hasp, push the body down until the 5-pin cylinder engages, then turn the key to lock; the step often missed is verifying the shackle clicks fully into both locking notches.

What maintenance or replacement will this padlock need later?

Lubricate the Master K6000 keyway and 5-pin cylinder annually with dry graphite; replace the lock if the brass body shows deep corrosion or the boron alloy shackle bends, as the core is not interchangeable.

What limit appears first under sustained outdoor use?

The brass body develops surface oxidation before the boron alloy shackle loses strength; the weather-resistant rating covers rain exposure but not continuous salt spray or acid environments.
