2. Laser‑Cut Keys
Laser‑cut keys have a more complex, double‑sided blade that avoids easy recreation by standard cutters. Devoted laser-cut makers encode the exact depth and angle of each cut, making sure a precise match.

Program the Transponder (if applicable)
- Connect the key developer to the OBD‑II port. Follow the on‑screen prompts to "discover" the brand-new key to the immobilizer system.
Test Remote Functions (if geared up)
- Verify lock/unlock, trunk release, and panic buttons. If cloning, use an RF duplicator to replicate the rolling‑code signal.
Last Verification
- Insert the duplicated key into the ignition and attempt to begin the engine. Confirm that all electronic features work as anticipated.
