Commercial steel padlock for keyed-alike access
This Master Lock padlock is built for commercial environments where multiple locks must open with the same key. The four-pin cylinder uses the Master K6000 keyway and ships keyed alike to number X2355, simplifying key management for maintenance teams and facility staff. A laminated steel body and hardened steel shackle resist physical attack, while the rectangular body profile fits standard hasps and chains. It is not suited for outdoor exposure because the manufacturer rates it as not weather resistant.
Sustained physical security without electronic
The lock relies entirely on mechanical operation, so performance does not degrade with time, temperature or power loss. The four-pin tumbler provides consistent resistance to picking and bumping across repeated daily cycles. Two bumpers cushion the shackle during frequent locking and unlocking, reducing wear on the body. Because there are no batteries, firmware or connectivity, the padlock remains functional indefinitely as long as the key is retained and the mechanism stays free of debris.
Replaces mixed key sets in managed facilities
This padlock replaces installations where each lock carries a different key, eliminating the need for large key rings and reducing the risk of lost credentials. The keyed-alike configuration is worth the switch when a single authorised person or team must secure multiple points such as equipment cages, utility rooms or gate chains. It does not serve buyers who need unique keys per lock, rekeyable cylinders, weather-rated exteriors or interchangeable core systems.

Questions about this item
Does the 4-pin cylinder generate any noise or heat during continuous outdoor use?
The lock is a purely mechanical 4-pin cylinder with no electronic parts, so it produces no heat and no operational noise.
What key do I already need to open the Master K6000 keyway marked X2355?
The padlock is keyed alike to X2355; only a key cut to that code and the Master K6000 keyway will operate it.
Will the 5/16-inch steel shackle fit the existing hasp on my older storage unit?
The shackle diameter is 5/16 in, clearance height 5 3/4 in and width 3/4 in; measure your hasp aperture and staple spacing against those dimensions.
