4. Setup and Key Making Process
The XKKF03EN remote key requires several steps to become fully functional for a specific vehicle. This process typically involves generating the remote, generating/cloning a transponder chip, cutting a key blade, and final assembly/installation. You will need an Xhorse VVDI programming tool for most of these steps.

- Remote Generation:
Using your Xhorse VVDI programming tool, connect the XKKF03EN circuit board to the device. Select the appropriate vehicle make and model to generate the remote key data onto the circuit board. - Battery Installation:
Insert a CR2032 battery into the designated battery socket on the circuit board. Ensure correct polarity. (Note: Battery is not included and must be purchased separately). - Chip Generation / Transponder Editing & Cloning:
If your vehicle requires a transponder chip for immobilizer functions, you will need to purchase a compatible transponder chip separately. Use your Xhorse VVDI tool to generate or clone the transponder data onto this chip. - Key Blade Cutting:
Purchase an uncut key blade compatible with your vehicle. Take the key blade to a professional locksmith or use a compatible key cutting machine to cut it according to your original vehicle key. (Note: Key blade is not included and must be purchased separately). - Assembly and Installation:
Assemble the circuit board, battery, and cut key blade into the XKKF03EN key shell. Ensure all components fit securely. Once assembled, the key can be programmed to your vehicle using the Xhorse VVDI tool or a professional automotive locksmith.
5. Operating Instructions
Once the XKKF03EN remote key is fully programmed and assembled, it functions as a standard 3-button remote for your vehicle.
- Lock Button: Press once to lock all vehicle doors.
- Unlock Button: Press once to unlock all vehicle doors.
- Trunk Button: Press and hold (or press twice, depending on vehicle model) to open the vehicle's trunk or tailgate.
Refer to your vehicle's owner's manual for specific remote key operating procedures, as functionality may vary slightly between car models.
6. Maintenance
- Battery Replacement: The remote uses a CR2032 coin cell battery. If the remote range decreases or it stops responding, replace the battery. To replace, carefully open the key shell (refer to Figure 3 for internal components), remove the old battery, and insert a new CR2032 battery with the positive (+) side facing up.
- Cleaning: Clean the key with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the plastic or metal components.
- Storage: Store the key in a dry place, away from extreme temperatures and direct sunlight. Avoid dropping the key or exposing it to water.
7. Troubleshooting
If you encounter issues with your XKKF03EN remote key, consider the following:
- Remote Not Responding: Check the battery. Ensure it is correctly installed and has sufficient charge. If the battery is new, re-check the remote generation and programming steps with your VVDI tool.
- Key Not Starting Vehicle: If the key turns in the ignition but the car does not start, the transponder chip may not be correctly programmed or installed. Revisit the chip generation/cloning process.
- Buttons Not Functioning: This could indicate a programming issue or a faulty circuit board. Re-program the remote using your VVDI tool. If the issue persists, the circuit board may need replacement.
- Physical Damage: Inspect the key for any visible damage. If the key shell is cracked or buttons are stuck, it may affect functionality.
For complex issues, it is recommended to consult a professional automotive locksmith or contact Xhorse technical support.
