How Do I Get My Key Out Of The Trunk Of My Jaguar 2005 X Type 3.0 Vdp

without taking it to dealership - there is no release button inside the car, the trunk only opens with the key remote button - the seats release is in the trunk - AAA opened my car doors but not able to open trunk - the dealership can do it by having my car towed to them so they can make a new key which needs to be programmed to the car at the dealership.  is there anything else that can open the trunk like removing the seat, if so how.  if not, is there any other way... the dealership will cost $400 to do a key and open it, key alone is $250 plus $100 labor plus tax, plus my tow etc. PLEASE HELP
