Button-less Combination Change Process

  • No Buttons to Push | No Doors to Open | No Accidental Combination Changes

    Button-less Combination Change Process

    Master Lock‘s newest technology, the Button-less Combination Change process allows staff to easily change built-in lock combinations for the new year and reduce maintenance time.

    We‘ve removed the button on the back case of the lock, so the whole process can be performed on the outside of the locker door with just your control key. No more opening every single locker door in your facility!

    Without the button, you won‘t have to worry about accidental combination changes due to an overstuffed locker, which will save time throughout the year.
