Setup and Programming
Before beginning the programming process, ensure you have a functional original car key. The programming tool is designed for ease of use with on-screen prompts.
Pre-Programming Check:
- Check New Key Fob Battery: Before using the OBD tool, verify the functionality of the new remote key by checking its light. If the light is dim or non-existent, replace the CR2032 battery.

Programming Steps:
- Locate OBD2 Port: Identify the OBD2 port in your vehicle, typically located under the steering wheel.
- Connect OBD Tool: Plug the receiver of the OBD tool into the vehicle's OBD2 port.
- Follow On-Screen Prompts: The OBD tool features a screen that will display clear instructions. Follow these prompts carefully to complete the programming process. No mobile app or Bluetooth connection is required.
- Verify Board Number: Ensure the original key's internal board shows the letters "GNE" and numbers "5290" stamped on it for proper compatibility.
- Test New Key Fob: After programming, test all functions of the new key fob (lock, unlock, trunk, panic alarm) to ensure successful pairing.

- Lock Button: Press to lock all vehicle doors.
- Unlock Button: Press to unlock all vehicle doors.
- Trunk Release Button: Press and hold to open the vehicle's trunk or liftgate.
- Panic Alarm Button: Press the red button to activate the vehicle's panic alarm. Press again to deactivate.
Maintenance
The key fob is equipped with a CR2032 battery. If the key fob's signal weakens or the indicator light does not illuminate when a button is pressed, the battery may need replacement.
Battery Replacement:
- Carefully open the key fob casing.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive (+) side facing up.
- Close the key fob casing securely.
- Test the key fob functions to ensure proper operation.
Troubleshooting
If you encounter issues during or after programming, consider the following troubleshooting steps:
- Programming Failure: If the key fob does not program on the first attempt, repeat the programming steps carefully. Ensure all connections are secure and on-screen prompts are followed precisely.
- Key Fob Not Responding: Check the battery in the new key fob. A weak or dead battery can prevent proper operation. Refer to the "Maintenance" section for battery replacement instructions.
- Specific Button Malfunction: If certain buttons (e.g., trunk release) do not work, re-attempt the programming process. Ensure the key fob is fully compatible with your vehicle's specific features.
- Original Key Requirement: Remember that a usable original car key is required for the programming process. Without it, the kit cannot be used.
- Compatibility Check: Double-check that your vehicle's model, year, FCC ID (HYQ14ACX), and original key's internal board number (271451-5290 GNE) match the product's specifications. Incompatibility is a common reason for programming issues.
