2.3 Key Blade Cutting

The key blade provided with this shell case is uncut. It does not include CNC cutting service. You have two options for cutting the key blade:

3. Operating Instructions

Once the internal electronics and the cut key blade are properly installed in the new shell case, the key fob will function identically to your original key. Use it to unlock/lock your vehicle and start the engine as usual.

4. Maintenance

To ensure the longevity and proper functioning of your key shell, follow these maintenance tips:

• Keep the key fob clean and free from dust and debris.
• Avoid exposing the key fob to extreme temperatures or direct sunlight for prolonged periods.
• Do not drop the key fob or subject it to strong impacts, as this may damage the internal electronics or the shell itself.
• If the key blade becomes stiff, a small amount of graphite lubricant can be applied.

5. Troubleshooting

If you encounter issues after assembling your new key shell, consider the following:

• Key Not Functioning: Double-check that the circuit board and transponder chip are correctly seated and oriented within the new shell. Ensure all connections are secure.
• Key Blade Not Turning: Verify that the key blade was cut accurately to match your original key. If not, it may need to be re-cut or replaced.
• Loose Components: If the shell feels loose, ensure all screws (if applicable) are tightened and the case is fully snapped together.
