I read several posts on how to open trunk but nothing I seen works. My truck actuater works but trunk wont fully release to open. I used my car key but only turns about 80% to the right.

Is there another method beside drilling hole behind license plate?

 

Have you seen this thread?... https://www.jaguarforums.com/forum/x...7-xj6-l-58480/ ....there's a later post where he went through the hole holding the tag on.
