  • Keyed-alike convenience using Master K81 keyway number 10R41

Commercial Steel Padlock

This Master Lock padlock is a commercial-grade security device built with a laminated steel body and hardened steel shackle. It suits business owners, facility managers and homeowners who need reliable keyed-alike access for gates, storage units or equipment cages. The 5-pin cylinder and Master K81 keyway provide pick resistance for moderate-security applications.

Keyed Alike Convenience

The lock arrives configured to open with key number 10R41, so multiple units share a single key and reduce key-ring clutter. Two bumpers on the shackle help protect the locked object from scratches during daily use. No control-key registration is required and the cylinder is not rekeyable, keeping key management straightforward for authorised personnel.

5-Pin Cylinder Security

The five-pin tumbler mechanism is the core specification that determines whether this padlock meets your threat model. It resists casual picking and bumping but is not rated for high-security environments requiring interchangeable cores or weather-sealed internals. Buyers who need more pins, a rekeyable core or a weather-resistant seal should look elsewhere.

Questions about this item

Will the 5-pin cylinder need lubrication or replacement over time?

The 5-pin cylinder is not rekeyable; if the mechanism wears, the entire padlock must be replaced rather than serviced.

What stops the shackle from being forced under sustained attack?

The 5/16-inch diameter steel shackle and laminated steel body provide the physical resistance; no interchangeable core is present to upgrade.

Does the lock heat up or make noise when left locked outdoors all day?

It has no moving electronics or motor, so it produces no noise or heat during continuous outdoor use.
