Traditional Mechanical Cutting
This technique mirrors the timeless "cutting a key by eye" method. The service technician copies the bitting pattern from the original key onto a suitable blank utilizing a rotary or milling maker. It's ideal for older automobiles that lack electronic security components.
2. Laser‑Cut Keys
Laser‑cut secrets have a more intricate, double‑sided blade that avoids simple reproduction by standard cutters. Dedicated laser-cut makers encode the precise depth and angle of each cut, ensuring an accurate match.
3. Transponder Programming
The majority of contemporary cars utilize an RFID transponder that interacts with the car's immobilizer. After cutting the blade, the brand-new key must be set 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 need a complete "learn" procedure by means of the car's onboard diagnostic port.
Step‑by‑Step Workflow for Duplicating an Auto Key

- Choose a key blank that matches the original's profile, blade type, and chip area.
Cut the Blade
- Manual Cut: Transfer the bitting pattern utilizing a key gauge. Laser Cut: Use a laser cutter with the appropriate code card. Mill Cut: For side‑winder keys, use a rotary mill with correct depth determines.
Program the Transponder (if appropriate)
- Connect the key programmer to the OBD‑II port. Follow the on‑screen prompts to "discover" the 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.
Final Verification
- Place the duplicated key into the ignition and effort to start the engine. Confirm that all electronic features work as expected.
Document and Label
- Tape-record the key's identification number, shows date, and any notes in the store's job management system.
