To add a ID47 smart key for the Kia K5 (also known as Kia Cadenza or Kia K8) 2017-, you will normally need to look up or purchase the vehicle’s password. However, the Keydiy KD-X4 offers an alternative solution – it allows you to clone a new smart key without password.
Begin by removing the key shell to access and identify the main control chip inside.
- For original keys fitted with the 29A7 chip model, the KD-X4 now supports direct writing to an original key.
- For other 29Ax series chip models, need to write chip data to the KD C29AX71 universal smart remote.
You can either refer to the wiring diagram displayed on the device itself, or check the wiring diagram provided here. Follow the diagram carefully to connect the key board to the device correctly.
Once the key is properly connected, read the key chip data through the device. After the data has been successfully read, write it into a new or used original factory key.
During this step, select the “Write to Original Key”.
Post-Programming Testing:
After the cloning process is complete, test both the engine start and key functions to confirm they are working properly.
Test the remote functions on both keys separately. If you encounter a remote sync loss issue, simply perform an emergency start once – this will resolve the remote synchronization problem.
Finally, verify that the passive entry (keyless entry) and one-touch push-start functions are operating correctly inside the vehicle.
