Fob nor inside trunk release will not open trunk.
Does anyone have a solution?

 

Have you tried the key in the trunk release. The slot is on the underside of the trunk rear trim, next to the number plate lights.

 

You didn't mention the release button on the trunk lid; it's beneath the 'chrome' strip, midway between the 'G' and 'U' of Jaguar; you can feel it as a round button about an inch in diameter.

The key release is a little to the right of the release button, almost directly beneath the 'U'. This is purely mechanical and it can be quite stiff, and it probably helps to press down on the trunk lid as you try to turn it.
