2. Laser-Cut (Sidewinder) Blades
Frequently found on modern-day or high-end automobiles, these blades are thicker and have a groove cut into the center of the blade face rather than the edges. They need specialized CNC (Computer Numerical Control) machines for repair or replacement.
3. Flip or Switchblade Keys
These secrets include a blade that folds into a plastic fob. The typical point of failure here is often the hinge system or the pin holding the blade in location, instead of the metal itself.

Step 3: Precision Cutting
Using a key-cutting device, a new blank blade is sculpted. For laser-cut secrets, this includes high-precision milling.
