Losing or needing to replace your 2004 Jaguar Xj8 Key Fob can be a frustrating experience. Fortunately, programming a new or existing key fob for your Jaguar XJ8 might be simpler than you think. This guide provides a step-by-step process to potentially program your 2004 Jaguar XJ8 key fob yourself, saving you time and money. While dealership programming is always an option, understanding the DIY method can be incredibly helpful.
Programming Your 2004 Jaguar XJ8 Key Fob – Method 1
This method is based on general Jaguar programming procedures and may work for your 2004 XJ8. It involves using the car’s central locking system to enter programming mode.
-
Prepare Your Jaguar: Begin by opening both the boot lid (trunk) and the driver’s side door of your 2004 Jaguar XJ8. Ensure the ignition is switched off before you start.
-
Turn On the Ignition: Switch the ignition to the “ON” position. This is usually done by turning the key to the position just before starting the engine. You should see the dashboard lights illuminate.
-
Enter Learning Mode: Locate the central locking switch in your 2004 Jaguar XJ8. This is typically found on the center console. Press and release this central locking switch five times in quick succession. If successful, the car’s siren should chirp once. This chirp indicates that your Jaguar XJ8 has entered the key fob learning mode, ready to accept programming.
-
Program the First Key Fob: Take the key fob you wish to program for your 2004 Jaguar XJ8. Press the “lock” button on the key fob. If the programming is successful, the system should chirp once again to confirm that it has received and learned the signal from this remote.
-
Program Additional Key Fobs (Optional): If you have more key fobs to program for your 2004 Jaguar XJ8, press the central locking switch once more. The system should now chirp twice, indicating it is ready to program the second key fob. Press the “lock” button on the next key fob. Repeat this process for any additional key fobs you need to program, increasing the chirps by one for each subsequent fob (three chirps for the third fob, and so on).
-
Exit Learning Mode: After you have programmed all desired key fobs, wait for approximately 30 seconds. The system should automatically close the programming mode and chirp twice to confirm the process is complete.
-
Test Your Key Fobs: Thoroughly test each programmed key fob to ensure it correctly locks and unlocks the doors, and activates any other remote functions for your 2004 Jaguar XJ8, such as the boot release or panic alarm.

Important Notes and Troubleshooting
- Timing is Key: The speed at which you press the central locking switch is important. Ensure you are pressing it quickly and consistently for the system to recognize the input and enter programming mode.
- Siren Chirps: Pay close attention to the siren chirps. They are your primary indicator of whether you are successfully entering and navigating the programming sequence. If you do not hear chirps, restart the process from step 1 and ensure the ignition is correctly in the “ON” position.
- Battery Condition: Ensure the batteries in your key fobs are in good condition. Weak batteries can sometimes prevent successful programming.
- Model Variations: While this method is generally applicable, there might be slight variations depending on the specific trim level or optional features of your 2004 Jaguar XJ8. Always refer to your owner’s manual for the most accurate instructions for your specific vehicle.
- Professional Help: If you encounter difficulties or the programming process is unsuccessful, it is recommended to consult a professional locksmith or your local Jaguar dealership. They possess specialized tools and diagnostic equipment to program your key fob or diagnose any underlying issues with your vehicle’s security system.
By following these steps, you can attempt to program your 2004 Jaguar XJ8 key fob yourself. Successful DIY programming can save you the expense of dealership programming and get you back on the road quickly with a functioning key fob.
