Master Lock 6840KA-10G111 Padlock Keyed Alike Brass Body

Rectangular Brass Padlock Keyed Alike

The Master Lock 6840KA-10G111 is a rectangular brass-bodied padlock supplied keyed alike to key number 10G111. It uses a five-pin cylinder on the Master K6000 keyway and a boron-alloy shackle. The lock is rated for high security and weather resistance, making it suitable for outdoor gates, sheds or storage units where multiple locks must share one key.

Mechanical Push-Button Limits

This model relies on a purely mechanical push-button mechanism rather than an electronic or smart interface. There is no audit trail, remote access or code-change capability. The shackle dimensions are fixed at 5/16 in diameter, 1 3/16 in height and 25/32 in width, so the lock cannot fit hasps or chain links larger than those clearances. The cylinder is not interchangeable and control-key registration is not required.

Straightforward Installation Common Issues

Installation consists of inserting the shackle through the hasp and snapping the body shut; no tools or wiring are involved. Because the locks arrive keyed alike, every unit in the pack opens with the same 10G111 key, eliminating key-management errors. The most frequent problem is debris or corrosion jamming the push-button latch over time, especially in salty or dusty environments, which can prevent the shackle from releasing even with the correct key.
