This method only works on Jaguar vehicles that have the battery in the engine bay or have a jump start terminal in the engine bay. 

The idea is that you will power up the vehicle then use the trunk release to open the trunk. 

  1. Pull the hood release under the dashboard. 
  2. Go to the front of the vehicle and release the hood. Lift up the hood and make sure it stays open. 
  3. Locate the positive (+) on the batter or the jump start terminal. 
  4. Connect the red clamp of a jump starter to the positive (+) terminal. 
  5. Connect the black clamp of a jump starter to an unpainted bolt on the frame. Don't connect it to the negative battery terminal. 
  6. Turn on the jump starter. 
  7. Locate the trunk release and open the trunk. 

If the battery in your Jaguar has died or the keyfob remote will no longer work, you will need to manually unlock the door or trunk.
