Conventional Mechanical Cutting

2. Laser‑Cut Keys
Laser‑cut keys have a more intricate, double‑sided blade that prevents simple reproduction by standard cutters. Dedicated laser-cut devices encode the precise depth and angle of each cut, guaranteeing a precise match.
3. Transponder Programming
Many modern-day cars utilize an RFID transponder that interacts with the car's immobilizer. After cutting the blade, the new key needs to be configured to the car's ECU utilizing a professional developer. Failure to program the chip results in a non‑starting vehicle.
4. Remote or FOB Duplication

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 replicate 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 anticipated.
File and Label
- Record the key's serial number, shows date, and any notes in the store's job management system.
