Step-by-Step Key ID Change Guide

Follow these steps to successfully change the Key ID using your Keydiy KD-X4.

Step 1: Extract Information from the Original Key

Start by disassembling the original factory key to access its internal data. This process involves generating a service code which is essential for future steps. Using the Keydiy interface, you will notice two Key IDs appearing on the screen. To identify which Key ID belongs to your original key, place it on the induction coil of the KD-X4.

Step 2: Set Up the Keydiy Remote

Modification of the ID is strictly applicable to Keydiy remotes. Navigate through the programmer’s menu to select the service code you previously generated. Make sure to choose the FGB remote option to create a new dealer key.

Step 3: Adjust the Key ID on the New Remote

Moving on to the Chip function, select the option for Automation detection clone. Position your Keydiy FGB remote on the Keydiy KD-X4 induction coil. Press the start button to allow the device to recognize the chip type and the current ID. Once the ID is displayed on screen, select the Chip editing option and modify it to match the original ID obtained in Step 1. Don't forget to finalize this process by writing the edited ID back to the chip — a confirmation message will let you know if it was successful.

Step 4: Confirm the Update

In this step, perform another identification check on the remote. This verification ensures that the Key ID has been properly updated to correspond to the original factory key. If the information aligns, you can confidently proceed to the next step.

Step 5: Finalize with Vehicle Programming

As the last step, once you've synced the Key ID with the original system, it’s time to teach the new key to your vehicle by following the established programming procedure. Ensure that you adhere to the vehicle's manufacturer's guidelines for seamless integration.
