Conventional Mechanical Cutting
This technique mirrors the timeless "cutting a key by eye" technique. The technician copies the bitting pattern from the original key onto a suitable blank using a rotary or milling device. It's ideal for older automobiles that lack electronic security elements.
2. Laser‑Cut Keys
Laser‑cut keys have a more intricate, double‑sided blade that prevents simple reproduction by basic cutters. Committed laser-cut devices encode the exact depth and angle of each cut, ensuring an accurate match.
3. Transponder Programming
Most modern-day cars use an RFID transponder that communicates with the car's immobilizer. After cutting the blade, the brand-new key needs to be configured to the car's ECU using an expert developer. Failure to configure the chip leads to a non‑starting car.
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" treatment via the car's onboard diagnostic port.

- Choose a key blank that matches the original's profile, blade type, and chip place.
Cut the Blade
- Manual Cut: Transfer the bitting pattern using a key gauge. Laser Cut: Use a laser cutter with the correct code card. Mill Cut: For side‑winder secrets, utilize a rotary mill with correct depth gauges.
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, utilize an RF duplicator to duplicate the rolling‑code signal.
Final Verification
- Insert the duplicated key into the ignition and attempt to begin the engine. Confirm that all electronic features work as expected.
Document and Label
- Record the key's identification number, programs date, and any notes in the store's task management system.
