Conventional Mechanical Cutting
This technique mirrors the classic "cutting a key by eye" method. The technician copies the bitting pattern from the initial key onto a compatible blank utilizing a rotary or milling maker. It's ideal for older cars that lack electronic security components.
2. Laser‑Cut Keys
Laser‑cut keys have a more complex, double‑sided blade that prevents simple reproduction by standard cutters. Dedicated laser-cut machines encode the exact depth and angle of each cut, making sure a precise match.
3. Transponder Programming
Most modern automobiles use an RFID transponder that communicates with the car's immobilizer. After cutting the blade, the new key must be configured to the car's ECU using a professional programmer. Failure to program the chip leads to a non‑starting lorry.
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 require Learn more here a full "find out" procedure through 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 correct code card. Mill Cut: For side‑winder secrets, use a rotary mill with correct depth gauges.
Program the Transponder (if appropriate)
- Connect the key programmer to the OBD‑II port. Follow the on‑screen triggers to "find out" the new key to the immobilizer system.
Test Remote Functions (if geared up)
- Verify lock/unlock, trunk release, and panic buttons. If cloning, utilize an RF duplicator to reproduce the rolling‑code signal.
Final Verification
- Place the duplicated key into the ignition and attempt to start the engine. Verify that all electronic features work as expected.
File and Label
- Record the key's serial number, programs date, and any notes in the store's job management system.
