1. Conventional Mechanical Cutting

This technique mirrors the timeless "cutting a key by eye" method. The professional copies the bitting pattern from the initial key onto a compatible blank using a rotary or milling maker. It's perfect for older vehicles that do not have electronic security parts.

2. Laser‑Cut Keys

Laser‑cut secrets have a more complicated, double‑sided blade that avoids simple reproduction by standard cutters. Dedicated laser-cut machines encode the precise depth and angle of each cut, guaranteeing an exact match.

3. Transponder Programming

Many modern vehicles use an RFID transponder that interacts with the car's immobilizer. After cutting the blade, the new key must be set to the car's ECU using a professional programmer. Failure to set the chip leads to a non‑starting automobile.

4. Remote or FOB Duplication

Keyless‑entry fobs consist of both a mechanical blade and a radio‑frequency circuit. Some fobs https://www.g28carkeys.co.uk/ can be cloned with a universal duplicator, while others require a full "discover" procedure via 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.

  3. Cut the Blade

    • Manual Cut: Transfer the bitting pattern utilizing a key gauge.
    • Laser Cut: Use a laser cutter with the proper code card.
    • Mill Cut: For side‑winder keys, use a rotary mill with correct depth determines.

  4. Program the Transponder (if appropriate)

    • Connect the key developer to the OBD‑II port.
    • Follow the on‑screen prompts to "discover" the new key to the immobilizer system.

  5. Test Remote Functions (if geared up)

    • Verify lock/unlock, trunk release, and panic buttons.
    • If cloning, use an RF duplicator to duplicate the rolling‑code signal.

  6. Last Verification

    • Place the duplicated key into the ignition and attempt to start the engine.
    • Confirm that all electronic features work as anticipated.

  7. File and Label

    • Record the key's identification number, programs date, and any notes in the shop's task management system.

Expense Considerations
