our patented Shape-Lock Method™
A visual targeting system made of a circle and directional arrow that trains your eye to aim square and stay on path, even when your perception shifts. It gives your brain something simple, repeatable, and accurate to lock onto from any angle.
Just a 2° face angle error causes putts to miss by 2+ inches from a distance of 5 just feet.
The Putter Key's precision system eliminates these costly mistakes, turning near-misses into made putts.
Center
The Key™ is the width of a golf ball, showing you the exact center of the face and training for proper placement.
AIM
Our proprietary design utilizes shapes, not just lines, for visual alignment, training to help you better aim the putter-face, which is essential.
PATH
The Key trains your back stroke using visual cues to ingrain the correct muscle memory. Draw the arrow back to the circle to create a correct path without outside manipulation.
cutting-edge putting science
Shape-Based Alignment System: Unlike traditional putting training aids that rely on confusing lines, the Putter Key uses intuitive shapes that your brain processes more accurately, making better putting alignment effortless and automatic.
Path Training Technology: The integrated arrow and back target circle system trains a straight takeaway, promoting the correct stroke path that's essential for consistent putting performance.
