Standard Mechanical CuttingThis method mirrors the traditional "cutting a key by eye" approach. The service technician copies the bitting pattern from the initial key onto a compatible blank using a rotary or milling machine. It's ideal for older cars that lack electronic security elements.
2. Laser‑Cut KeysLaser‑cut secrets have a more intricate, double‑sided blade that prevents simple recreation by basic cutters. Committed laser-cut devices encode the exact depth and angle of each cut, ensuring an exact match.
3. Transponder ProgrammingA lot of modern lorries use an RFID transponder that interacts with the car's immobilizer. After cutting the blade, the brand-new key must be configured to the car's ECU utilizing a professional developer. Failure to set the chip results in a non‑starting car.
4. Remote or FOB DuplicationKeyless‑entry fobs contain both a mechanical blade and a radio‑frequency circuit. Some fobs can be cloned with a universal duplicator, while others need a full "discover" treatment by means of the car's onboard diagnostic port.

Connect the key developer to the OBD‑II port. Follow the on‑screen triggers to "discover" the new key to the immobilizer system.Test Remote Functions (if equipped)
Verify lock/unlock, trunk release, and panic buttons. If cloning, use an RF duplicator to duplicate the rolling‑code signal.Final Verification
Insert the duplicated key into the ignition and effort to begin the engine. Verify that all electronic features work as expected.Document and Label
Tape-record the key's identification number, programming date, and any notes in the shop's task management system.
