Traditional Mechanical Cutting
This method mirrors the traditional "cutting a key by eye" approach. The specialist copies the bitting pattern from the original key onto a suitable blank using a rotary or milling device. It's perfect for older cars that do not have electronic security components.

3. Transponder Programming
Many modern-day automobiles employ an RFID transponder that communicates with the car's immobilizer. After cutting the blade, the brand-new key must be set to the car's ECU utilizing an expert developer. Failure to program the chip leads to a non‑starting vehicle.

4. Remote or FOB Duplication
Keyless‑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 "find out" procedure by means of the car's onboard diagnostic port.

Cut the Blade
- Manual Cut: Transfer the bitting pattern utilizing a key gauge. Laser Cut: Use a laser cutter with the proper code card. Mill Cut: For side‑winder keys, utilize a rotary mill with appropriate depth gauges.
Program the Transponder (if applicable)
- Connect the key programmer to the OBD‑II port. Follow the on‑screen triggers to "find out" the brand-new key to the immobilizer system.
Test Remote Functions (if equipped)
- Verify lock/unlock, trunk release, and panic buttons. If cloning, utilize an RF duplicator to duplicate the rolling‑code signal.
Last Verification
- Place the duplicated key into the ignition and attempt to begin the engine. Confirm that all electronic functions work as expected.
Document and Label
- Tape the key's identification number, shows date, and any notes in the shop's job management system.
