Traditional Mechanical Cutting
This method mirrors the classic "cutting a key by eye" method. The service technician copies the bitting pattern from the original key onto a compatible blank utilizing a rotary or milling device. It's perfect for older vehicles that do not have electronic security components.
2. Laser‑Cut Keys
Laser‑cut keys have a more intricate, double‑sided blade that prevents simple recreation by basic cutters. Devoted laser-cut machines encode the specific depth and angle of each cut, guaranteeing a precise match.
3. Transponder Programming
A lot of modern cars employ an RFID transponder that interacts with the car's immobilizer. After cutting the blade, the brand-new key should be set to the car's ECU utilizing an expert programmer. Failure to program the chip results in a non‑starting automobile.
4. Remote or FOB Duplication

Program the Transponder (if suitable)
- Connect the key developer to the OBD‑II port. Follow the on‑screen triggers 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 reproduce the rolling‑code signal.
Last Verification
- Place the duplicated key into the ignition and attempt to begin the engine. Verify that all electronic features work as expected.
File and Label
- Record the key's serial number, programming date, and any notes in the shop's job management system.
