Precision bump key for Master 3 variant padlock cylinders. Lock bumping converts a single hammer strike into a simultaneous jump of every driver pin in the cylinder - the brief ali gnment at the shear line is your opening. That result depends on a key cut to the exact specifications of the target keyway. Our M1 bump key is code cut for the Master 3 variant padlock keyway, so the geometry is right before you ever pick up the hammer.
