Design Securely store your keys with the satisfying sound and feel of a real lock. Use one or more to keep your keys organized. Looking for something less practical? Use a spare or 3D printed key to make a fidget toy. The locking mechanism works with almost any key!

How it works A series of spring-loaded disks allow keys to pass through when oriented vertically while hugging keys along their distinct profiles when oriented horizontally. A carefully shaped notch in each spring guides keys smoothly between orientations with minimal force required. The keyhole locks into vertical and horizontal orientations to keep things lined up nicely.
