- New Key Fob Case (Optional but Recommended): Consider replacing your key fob case at the same time, especially if your current case is worn or damaged. This can refresh the look of your key fob.
- Small Flat Blade Screwdriver: For opening the key fob case.
- Soldering Iron and Solder: To remove and replace the battery (basic soldering skills required).
- 1.5mm Drift or Drill Bit (Optional): For removing the key blade roll pin if you need to swap key blades.
- Multimeter (Optional): To test the old and new batteries.
Step-by-Step 2008 Range Rover Key Fob Battery Replacement Guide
Follow these steps carefully to replace your 2008 Range Rover key fob battery:
Step 1: Prepare Your Workspace and Gather Materials
Ensure you have a clean, well-lit workspace. Lay out all the tools and the new battery and key case (if using).
Step 2: Open the Old Key Fob Case
Using a small flat blade screwdriver, carefully pry open the old key fob case. Insert the screwdriver into the seam of the case and gently twist to separate the two halves. Be patient and avoid forcing it to prevent damage to the case.
Step 3: Open the New Key Fob Case (If Replacing)
If you are replacing the key fob case, open the new case in the same manner as the old one. Having both cases open side-by-side will help during the component transfer process.
Step 4: Access the Circuit Board and Battery
Carefully lift out the circuit board from the old key fob case. Turn the circuit board over to locate the battery. It is usually on the opposite side of the buttons.
Step 5: Remove the Old Battery
This step requires soldering skills. Use a soldering iron to carefully desolder the old battery from the circuit board. Heat the solder joints where the battery terminals are connected to the board. Once the solder is molten, gently remove the old battery.
Tip: To clear the locating holes of solder after removing the old battery, heat the solder in the holes until molten and quickly blow on it to clear the hole. Alternatively, you can use a solder sucker or desoldering braid if you have these tools.
Step 6: Prepare the New Battery
Remove the new VL2330 battery from its packaging. Some batteries come with a holder. If yours does, remove the battery from the holder. The holder itself is not needed for installation in the key fob.
Step 7: Install the New Battery
Carefully position the new battery onto the circuit board, ensuring the battery terminals align with the locating holes on the board. Push the battery terminals through the holes. Solder the new battery terminals to the circuit board, making sure you create solid solder joints.
Step 8: Test the Key Fob
Before reassembling the key fob, test it. Press the buttons on the circuit board to ensure the battery is correctly installed and the circuit board is functioning. You should see the LED light on the fob illuminate when buttons are pressed.
Step 9: Reassemble the Key Fob
Place the circuit board into the bottom half of the new key fob case (or the old case if you are not replacing it).
Step 10: Swap Key Blades (If Replacing Case and Needed)
In some cases, the old key blade may not fit perfectly into the new key fob case due to slight variations in manufacturing. If this happens, you will need to swap the key blades.
To do this, locate the small roll pin that secures the key blade to the hinge. Using a 1.5mm drift or drill bit, gently tap out the roll pin. Note that the pin will only come out in one direction as the hole sizes are different on each side. Once the pin is removed, pull out the key blade. Repeat this process for both the old and new key cases and swap the blades.
Step 11: Assemble the Key Fob Case
Locate the key blade assembly in the case and wind up the spring mechanism by rotating it anti-clockwise approximately three rotations. While holding the key blade in the folded position, insert the keyring holder to secure it, and then snap the top half of the key fob case onto the bottom half.
Tip: Some aftermarket key fob cases may simply snap together. For added security, you can apply a tiny drop of super glue at a few points around the inside edge of the case before snapping it together.
Step 12: Test Your Replaced Key Fob
Test your newly assembled key fob with your 2008 Range Rover. The doors should unlock and lock, and you should be able to start the vehicle.
