Conventional Edge-Cut Keys
These are the most typical kinds of older secrets. They include notches cut into the sides or "edges" of the blade. They are typically cut utilizing a duplicator machine that traces a current key to produce a replica.
Laser-Cut Keys (Sidewinder Keys)
Laser-cut keys are more secure and harder to reproduce. Unlike edge-cut keys, these have a consistent density and the "cut" is a winding groove routed into the center of the blade face.
Precision: These require high-end CNC (Computer Numerical Control) grating machines.Security: The lock cylinders for laser-cut secrets are much harder to pick.Versatility: Most laser-cut secrets are symmetrical, meaning they can be placed into the lock in either direction.The Importance of the VIN
