there was a problem with these where the boot latch mechanism breaks internally so although the elctrics work the tailgate wont open result tailgate needs broken into best to speak to your local landrover dealer or specialist

Remove the paneling from inside. Than you can use a flathead screwdriver to pry the latch rod and latch enough to pop open the door.
