Contactless Magnetic Locking
Magnetic Pin Tumblers eliminate direct mechanical contact between the key and internal locking pins, rendering physical pick tools completely ineffective.
Magnetic Repulsion Kinematics
- Neodymium Key Magnets: Permanent Neodymium (NdFeB) micro-magnets embedded in the key blade with specific north/south polarities.
- Floating Internal Pins: Internal magnetic pins inside the plug are pushed or pulled into alignment via magnetic repulsion rather than physical lifting.
- Pick Immunity: Because there is no mechanical keyway contact, tension wrenches and lock picks cannot feel or manipulate the magnetic pins.
Frequently Asked Engineering & Selection Questions
Q1: Can magnetic lock cylinders be picked with standard tools?
No. Magnetic pins require precise magnetic field polarities embedded in the key and cannot be manipulated by physical pick picks.
